If you’ve spent months religiously and meticulously applying eye cream, getting more sleep, drinking more water and wondering why your dark circles haven’t shifted, there is a decent chance the problem isn’t that nothing works. You might just be treating the wrong thing.

Because dark circles describe what you can see. They don’t tell you why you’re seeing it. The best way I can describe this is:

Dark eyes are a symptom, not a diagnosis. Stop treating the symptom and treat the diagnosis.

One person’s dark circles might genuinely be extra brown pigment in the skin. Another person’s might look purple because the skin is thin enough for the blood vessels underneath to show through. Someone else might not have particularly dark skin under their eyes at all, but a hollow is creating a shadow that makes it look dark.

Then, just to make life easier, plenty of people have two or three of those things happening at the same time.

And yet, for some reason (….profit), the aesthetics and skincare industry routinely sell all of them the same tiny pot of eye cream promising a miracle.

So before spending another £40 on something promising to make you look as though you’ve slept for nine uninterrupted hours every night since birth, let’s work out what we’re actually trying to treat.

What actually causes dark circles under the eyes?

There isn’t one answer.

Dark circles are generally split into a few broad groups depending on what is creating the darker appearance:

• Pigment, where there is genuinely more colour in the skin
• Vascular, where blood vessels or the tissue underneath are showing through thin skin
• Structural, where the shape around the eye creates a shadow
• Mixed, which is exactly what it sounds like. More than one cause at once

This is why two people can walk into clinic with what looks, at first glance, like exactly the same concern and leave with completely different treatment plans.

The useful question isn’t really:

“What treatment gets rid of dark circles?”

It is:

“Why do my under-eyes look dark?”

Once we know that, treatment becomes considerably less random.

First, look at the colour

Colour can give us some clues.

Not a perfect diagnosis, and certainly not an invitation to spend an hour examining yourself under the bathroom spotlight, but it helps us understand what may be contributing.

Brown or grey-brown dark circles

These are more likely to have a pigment component.

Pigment basically means melanin, the natural substance that gives our skin its colour.

Some people naturally have more pigment around their eyes. Sun exposure can make pigmentation darker, and irritation or inflammation can also leave extra pigment behind.

If you have eczema, allergies or regularly rub your eyes, for example, repeated inflammation can contribute to darker skin in the area.

The important point is that this is actually colour within the skin, which makes treatments aimed at pigmentation potentially useful.

Blue, purple or pinkish dark circles

This is where we start thinking more about vascularity.

Vascularity just means blood vessels. The skin around the eye is naturally very thin. In some people it is particularly thin or even translucent, which means the tiny vessels and darker tissues sitting underneath become much easier to see through it.

If you’ve ever looked at the veins on the inside of your wrist, you’re looking at a similar basic principle. The vein isn’t sitting on top of the skin. You’re seeing its colour through the skin covering it and the eye area can do exactly the same thing.

This is also why someone can be 20, 25 or 30 and have very obvious dark circles without having any meaningful “ageing” problem whatsoever. Sometimes you simply have thin skin and visible vascularity.

And this distinction matters enormously.

If the darkness you’re looking at is largely blood vessels showing through thin skin, endlessly attacking melanin with brightening creams isn’t solving your cause of dark eyes.

There may not be much excess pigment there to brighten in the first place.

What if my dark circles are actually shadows?

This is where things get particularly interesting.

Sometimes the skin isn’t actually much darker at all. It just looks dark because of the shape underneath it.

Under the eye, there is a natural groove running from the inner corner out towards the cheek. You may have heard this called the tear trough.

Some people naturally have a deeper hollow there and it can also become more noticeable as facial structure changes over time.

Light hits the raised areas of your face and creates shadow in the dip underneath. That shadow can look exactly like a dark circle.

You can often see this effect yourself because the darkness changes dramatically depending on where the light is coming from. Stand underneath a harsh ceiling light and suddenly you haven’t slept since 2004. Face a soft window light and half the problem disappears.

The skin hasn’t changed colour in those ten seconds.

The lighting has changed the shadow.

And unfortunately, if a physical hollow is creating most of the darkness, a brightening eye cream is NOT going to change the shape underneath your eye.

Eye bags can create dark circles too

Puffiness under the eyes can create another version of the same problem.

If tissue bulges forwards, it can cast a shadow immediately underneath it.

The result can be a lighter puffy area followed by a dark line beneath it, which the brain simply reads as dark circles.

There are lots of reasons eyes can look puffy. Allergies can do it. Fluid retention can do it. Lack of sleep can make it more obvious. Some people naturally have more prominent fat pads under their eyes, and these can become more noticeable over time.

A fat pad is simply a small pocket of fat that normally sits around the eye and helps cushion and support it.

If that fat becomes more prominent or bulges forwards, you get what most people would call an eye bag.

Again, this matters because we have now moved even further away from a pigmentation problem.

If a shadow caused by a prominent eye bag is creating the darkness, trying stronger and stronger pigment treatments isn’t particularly logical.

What about thin skin under the eyes?

This deserves its own section because it is incredibly common and often misunderstood.

The skin around the eyes is some of the thinnest skin on the body. Underneath it you’ve got muscle, blood vessels and deeper tissue. The less opaque that covering is, the more of what sits underneath you can see.

Think of putting a dark object underneath a thick piece of card compared with a thin piece of tissue paper. The object hasn’t suddenly become darker. You can simply just see it more clearly through the thinner material and that is essentially what can happen around the eyes.

When somebody has naturally thin periocular skin, and periocular simply means around the eye, the aim of treatment may therefore be to improve the quality, hydration, texture and support of the skin itself.

We are not trying to magically remove every blood vessel underneath it.

We are trying to improve what is sitting over them.

Why do dark circles get worse as we age?

Dark circles aren’t exclusively an age problem, but ageing can definitely make some of the things we’ve already discussed more noticeable.

Over time, skin generally becomes even thinner and produces less collagen.

Collagen is one of the main proteins that gives skin its structure and strength. You can think of it as part of the scaffolding holding everything together. And that scaffolding becomes less and less as we age.

So we lose volume around the cheeks and under-eyes, making hollows and shadows more obvious. The support holding the fat around the eye in place can change too, making eye bags more prominent.

So someone who already had slightly visible vessels at 25 may notice them more at 45 because the skin covering them has changed.

Someone who already had a small tear trough may find that hollow becomes more noticeable.

This isn’t because everybody suddenly develops a new disease called dark circles. The anatomy around the eye is just changing.

Why do my dark circles look worse when I’m tired?

Because tiredness can absolutely make them look worse.

It just isn’t necessarily the original cause.

Poor sleep can make the skin look paler, which can make blood vessels underneath stand out more. It can contribute to puffiness around the eyes, which creates more shadowing. Dehydration can make the whole area look more sunken and dull.

So yes, getting decent sleep may improve how your under-eyes look.

But if you have inherited pigmentation, naturally thin skin or a deep tear trough, eight hours of sleep is not going to completely redesign your face overnight.

This is why telling everyone with dark circles to drink more water and sleep more is a bit like telling everyone with back pain to buy a better chair.

It might help some people but as above, it is not a diagnosis.

Can allergies cause dark circles?

Yes, particularly if allergies make your eyes itchy and you repeatedly rub them.

Rubbing causes irritation and inflammation. In some skin types, inflammation can leave extra pigment behind afterwards, which is called post-inflammatory hyperpigmentation.

That phrase sounds much worse than it is.

It simply means the skin became inflamed, then stayed darker afterwards.

Allergies can also cause puffiness around the eyes, which can create more shadow.

If your eyes are regularly itchy, watery, swollen or irritated, dealing with the allergy itself may therefore be far more useful than buying increasingly expensive eye creams.

So how do we actually work out what is causing yours?

When assessing dark circles, we’re looking at more than whether the area looks dark.

We look at the colour.

We look at the skin itself and basically aim to answer a few questions:

Can we see obvious blood vessels underneath it?

Is there genuinely brown pigmentation?

Is the skin very thin or crepey?

Is there a visible hollow?

Are prominent eye bags creating shadow underneath?

Does the darkness change significantly depending on the lighting?

Is there redness, eczema or evidence of repeated irritation?

And importantly, is there more than one thing happening?

Because mixed dark circles are extremely common.

Someone might have thin skin with visible vessels and a mild hollow.

Someone else might have pigmentation and puffiness.

Another person might have beautifully healthy skin but a deep structural shadow that no amount of resurfacing treatment is going to completely remove.

This is why I’m not a huge fan of choosing an under-eye treatment from a menu before anybody has actually looked at your eyes.

Do eye creams actually work for dark circles?

Some do something useful. None do everything.

That’s probably the most sensible way to approach them.

Caffeine

Caffeine is very popular in eye creams, particularly products aimed at puffiness and vascular-looking dark circles.

It can temporarily constrict small blood vessels, which means they become narrower for a period of time, and may help reduce puffiness in some people.

That can make the area look brighter temporarily. The key word though is temporarily.

Caffeine isn’t permanently removing the blood vessels and it certainly isn’t rebuilding a deep tear trough.

It can still be useful. It just needs a realistic job description.

Retinoids

Retinoids are vitamin A-related ingredients.

Retinol and retinal are the versions you’ll probably recognise from skincare brands.

Over time, retinoids can improve skin texture and support collagen production, which potentially makes them useful where fine, thin or crepey-looking skin is contributing to the problem.

The eye area is also particularly easy to irritate.

So this isn’t an area where I’d immediately introduce the strongest retinoid you can find and hope for the best. If you are new to retinoids, start with Geek and Gorgeous A-game 5*, before moving onto a-game 10* depending on tolerance and finally onto a-game 20* when you can finally cause yourself a retinoid veteran and have proven tolerance with the lower doses.

If the skin becomes red, dry and inflamed, you’ve just made the eye area look worse while trying to make it look better.

Vitamin C and other pigment-targeting ingredients

If pigmentation is genuinely part of the problem, vitamin C can help, but it is definitely not the only option.

Tranexamic acid (TXA) is particularly useful because it helps interrupt some of the signalling involved in excess pigment production. Azelaic acid can also help with pigment while bringing anti-inflammatory benefits, and ingredients such as alpha-arbutin, kojic acid, thiamidol and niacinamide can all target pigmentation in slightly different ways.

Vitamin C, like the Geek and Gorgeous C-Glow*, still has a place, particularly for its antioxidant effects and its ability to help with uneven pigmentation, but I wouldn’t treat it as the automatic first choice just because it appears in almost every brightening eye product.

The important bit is still this: if pigment isn’t actually the reason the area looks dark, pigment-targeting skincare is unlikely to solve the problem.

Moisturiser

Probably the least exciting product in this entire article, but worth mentioning.

Dry, dehydrated skin shows texture and fine lines more clearly.

A good moisturiser can make the eye area look smoother and less crepey simply by improving hydration.

It isn’t treating a tear trough. It isn’t removing pigment. It isn’t performing vascular surgery while you sleep.

But healthier, better-hydrated skin usually looks better than dry, irritated skin, so it absolutely has a role.

SPF

If pigmentation is part of your dark circles, sun protection matters.

UV exposure stimulates melanin production and contributes to longer-term collagen damage, so broad-spectrum sunscreen helps prevent us making both pigment and skin-quality problems worse.

You don’t need a microscopic 15ml luxury eye SPF that costs the same as an all inclusive holiday to the Maldives, but you do need adequate sun protection around the area with a product you can comfortably tolerate and will use consistently!!

What about those £80 eye creams?

There are excellent expensive products. There are excellent cheap products.

There are also shit examples of both.

Price does not tell you whether a product matches the reason your under-eyes look dark, and that is the real problem with buying a dark circle cream.

Imagine three people standing next to each other.

The first has brown pigmentation.

The second has thin skin with visible vessels.

The third has a deep tear trough creating shadow.

They all buy the same product because the box says FOR DARK CIRCLES.

That product would have to suppress pigment, make thin skin less translucent, remove visible vascularity and alter facial anatomy simultaneously.

It’s asking a great deal from 15ml of cream.

What professional treatments actually help dark circles?

This is where we come back to cause.

There is no sensible answer to “what’s the best dark circle treatment?” without first deciding what we are trying to change.

If your dark circles are mainly pigmentation

Now pigment-targeting treatments make sense.

That might include appropriate home skincare, professional chemical peels or, in some settings, laser or light-based treatments.

Chemical peels use carefully selected acids to create controlled exfoliation and skin renewal.

Different peels contain different ingredients and have different jobs, so again, a chemical peel is not one treatment.

At Renovo, I use Mesoestetic MD Periocular, a professional peel designed specifically for the eye area.

Mesoestetic includes both pigmented and vascular dark circles among the indications for this peel, alongside concerns such as fine lines and reduced skin density.

The aim isn’t to burn pigment away. It is a controlled treatment performed over the upper and lower periocular area according to the skin concern and treatment plan.

What if the problem is thin skin and visible blood vessels?

This is where treatment gets more interesting because simply brightening the area may not be enough.

If the darker appearance is being created because underlying vessels are visible through very thin skin, one approach is to work on the quality of the skin covering them.

That can include treatments aimed at hydration, texture, firmness and general skin quality.

At Renovo, depending on the person, that might include Mesoestetic MD Periocular, polynucleotides or NCTF 135 HA.

These treatments are not interchangeable and they aren’t simply three different brands of the same thing.

They work differently.

Polynucleotides

Polynucleotides are injectable chains made from purified fragments of DNA.

That sounds like we’ve suddenly left skincare and entered Jurassic Park, so translated into normal English:

they’re injected into the skin with the intention of supporting the environment in which skin repair and renewal take place.

They are used as a skin-quality treatment, particularly in delicate areas such as the under-eyes.

The available research around polynucleotides is promising for things such as hydration, elasticity, texture and fine lines, but it is still developing. There are relatively small studies, different products and different treatment protocols, so I don’t think it’s reasonable to describe them as a guaranteed cure for dark circles.

And they do not physically remove the blood vessels underneath your eyes. What we are trying to improve is the skin sitting over them.

NCTF 135 HA

NCTF 135 HA is another injectable skin treatment, but it isn’t a polynucleotide.

It contains non-crosslinked hyaluronic acid alongside a mixture of amino acids, vitamins, minerals and other ingredients.

Hyaluronic acid is a substance that binds water, so hydration is a major part of what we’re trying to improve.

With NCTF around the eyes, the goal is better hydration, smoother texture and improved general skin quality rather than adding facial volume.

We aren’t filling a hollow and we aren’t destroying a vessel. We’re just treating the skin.

Can a peel really help vascular-looking dark circles?

Potentially, but this needs explaining properly because it sounds counterintuitive.

A chemical peel is obviously not removing veins.

With something such as Mesoestetic MD Periocular, the aim is to improve the condition and appearance of the skin in the eye area over a treatment course.

Mesoestetic specifically lists both vascular and pigmented dark circles among the indications for its MD Periocular peel.

That doesn’t mean every purple under-eye will disappear after a peel.

If the vascularity is very prominent or deeper treatment of the vessels themselves is required, vascular laser treatment may make more sense and that is something we would need to discuss or refer appropriately.

The point is that treating visible vascularity isn’t always the same thing as treating the vessel itself.

Sometimes we’re working on the skin covering it. Sometimes the vessel is the thing that needs targeting.

What if my dark circles are caused by hollows?

This is where I would rather tell somebody the truth than sell them six skin treatments that aren’t going to solve the main problem.

If the majority of your darkness is a shadow caused by a deep tear trough or significant volume loss, improving skin quality may make the area look better, but it cannot completely change the underlying structure.

Treatments designed to correct structural hollowing include things such as carefully selected dermal filler or fat transfer, depending on the anatomy and the practitioner assessing it.

Renovo does not currently offer dermal filler.

So if I assess somebody and genuinely think the main problem is structural, I’m not going to pretend a peel or course of polynucleotides will somehow perform the same job.

We can improve the skin.

We cannot pretend the hollow isn’t there.

Sometimes the most useful consultation ends with “I don’t think what I offer is the best treatment for this.”

That’s still a useful consultation.

What about prominent eye bags?

The same principle applies.

Mild puffiness caused by things such as poor sleep, allergies or temporary fluid retention is one thing.

A genuinely prominent fat pad is another.

If there is significant bulging of the fat beneath the eye, skin treatments will not physically put that fat back where it came from.

They might improve skin quality around the area, but the structural problem remains.

For significant lower eyelid bags, surgical assessment may ultimately provide a more definitive option than repeatedly throwing aesthetic treatments at them.

Not particularly useful for selling you a package but very useful for not wasting your money.

What about fine lines and crepey skin?

Now we are back firmly in skin-quality territory.

Fine, dry or crepey skin under the eyes reflects light differently and can make the whole area look darker and more tired.

Improving hydration can help.

Treatments that stimulate skin renewal or collagen can also make sense depending on the person.

This is where options such as polynucleotides, NCTF, selected chemical peels and other skin-quality treatments may be useful.

It is also why somebody can improve their dark circles even when we haven’t directly treated pigment or blood vessels.

If the surface becomes smoother and the skin quality improves, the entire area can reflect light differently and simply look healthier.

Why might we combine treatments?

Because most people don’t arrive with one perfectly isolated problem.

You might have:

• naturally thin skin
• visible vessels
• a small amount of pigmentation
• fine lines
• mild hollowing

If we improve the pigment but ignore the thin skin, you’ll still see some darkness.

If we improve skin quality but ignore significant pigmentation, you’ll still see some darkness.

If we improve both but you’ve also got a deep structural hollow, you’ll probably still have some shadow.

This is why I’m increasingly wary of treatment packages built around “three sessions of X” before we’ve properly worked out what X is supposed to fix. Yes, we offer this to be transparent with pricing, but we will always ensure that your plan is bespoke to you.

Sometimes a course of one treatment makes perfect sense. Sometimes a staged plan using different treatments makes even more sense.

The treatment follows the problem, not the other way around.

Can you completely get rid of dark circles?

Sometimes people get a dramatic improvement, and sometimes the realistic outcome is more modest.

And sometimes there is a part of the problem we simply cannot change without moving into a completely different type of treatment.

It depends on the cause.

If somebody has mild pigmentation and responds beautifully to pigment treatment, great.

If somebody has thin skin, prominent vessels, a tear trough and a strong genetic tendency towards dark circles, promising to make them completely disappear would be ridiculous.

The aim is to understand which parts are realistically treatable, then decide whether the likely improvement is worth the treatment.

That might not sound as exciting as erase your dark circles. It is, however, considerably less likely to leave you disappointed afterwards.

How long does dark circle treatment take?

Again, there isn’t one timeline because there isn’t one treatment.

Some temporary improvements in hydration can appear fairly quickly.

Pigmentation usually takes time to change.

Treatments designed to improve skin quality and collagen work gradually because your skin actually has to go through the biological process of repairing and remodelling itself.

With things such as polynucleotides or NCTF, we normally think in terms of a course of treatment, then review the result rather than judging everything from one appointment.

Chemical peels may also be used as a course depending on the indication and the person’s response.

This is another area where photographs matter.

If you stare at your own face every morning, small changes are surprisingly difficult to notice. Side-by-side photographs taken in the same lighting are much less forgetful than your brain.

Is dark circle treatment painful?

Depends what we’re doing.

Topical skincare obviously shouldn’t involve much drama unless you’ve chosen something your skin hates.

Chemical peels around the eyes can sting or feel hot while they are active and particularly when being neutralised (albeit, only for about 10-15 seconds). The intensity depends on the peel and the person’s skin, and treatment is monitored throughout.

Injectable treatments involve multiple tiny injections, so pretending you won’t feel anything would be optimistic. The under-eye area can be sensitive.

Most people tolerate treatment perfectly well, but “completely painless” is not a phrase you’ll hear me casually throwing around. However, we do ensure to use advanced delivery needles which we’ve now shown numerous people to be comfortable enough to not require any numbing creams.

What treatment is best for purple under-eyes?

Purple or blue under-eyes often make us think about vascularity and thin skin, particularly if visible vessels are obvious.

The treatment plan might therefore focus on improving the quality of the overlying skin, or in some cases directly targeting vessels with a vascular device.

What makes considerably less sense is automatically assuming purple equals pigmentation and aggressively trying to bleach the area.

Colour is a clue.

It isn’t the whole assessment.

What treatment is best for brown dark circles?

Brown dark circles make pigmentation more likely to be involved.

That might lead us towards pigment-targeting skincare, careful sun protection, appropriate chemical peels or other pigment treatments depending on the person.

We would also want to know why the pigment is there. If somebody is constantly rubbing itchy eyes because of allergies or dermatitis, we need to address that too or the skin is simply going to keep getting irritated.

Why do I have dark circles even though I sleep enough?

Because sleep is only one possible factor.

You can sleep beautifully and still have:

• naturally thin under-eye skin
• visible blood vessels
• inherited pigmentation
• a tear trough
• prominent eye bags
• post-inflammatory pigmentation
• a combination of several of these

If your dark circles have been there since your teens and half your family has them too, another forty minutes in bed probably isn’t the breakthrough treatment we’ve been waiting for.

Are dark circles normal?

Absolutely.

They are incredibly common and, in most cases, completely harmless.

You do not medically need to treat them simply because they’re there.

But equally, if they bother you, there is nothing wrong with wanting to improve them.

The useful bit is having realistic expectations and choosing a treatment that actually corresponds with what is creating the appearance.

When should dark circles be medically assessed?

Dark circles themselves are usually a cosmetic concern, but not every change around the eye should automatically be dismissed as dark circles.

If you develop a new or sudden change, particularly if it is one-sided, painful, associated with significant swelling, redness, visual symptoms or another unexplained change around the eye, that deserves appropriate medical assessment. Persistent eczema, itching or significant irritation around the eyes should also be managed properly rather than repeatedly covered with cosmetic treatments. As much as I want to treat, it’s more genuine to tell you to seek medical expertise beforehand.

Dark circle treatment in Caerphilly

At Renovo, we offer mobile treatments in Caerphilly and across South Wales that may be useful for under-eye concerns, including polynucleotides, NCTF 135 HA and professional periocular chemical peels. We also provide home appointments near Cardiff; our mobile skin treatments near Cardiff page explains the areas we cover and the treatment options.

But this is one area where I’d strongly recommend not deciding what you need before either an informal chat or a proper consultation.

If your darkness is mainly caused by thin skin and visible vascularity, we may approach it one way.

If it is mainly pigmentation, we may approach it differently.

If the darkness is actually a structural shadow, I may tell you that the treatments I provide aren’t going to completely solve it.

And if, as is often the case, you’ve got a bit of everything going on, we can decide which part is worth tackling first.

Because the goal isn’t to sell you the treatment with the nicest before-and-after photographs.

It’s to work out why your eyes look dark and whether we have something that can realistically improve it.

Still not sure what is causing yours?

Good. You’re probably not supposed to diagnose your own face from a blog post.

That’s what the consultation is for where we can look at the colour, skin quality, visible vascularity, pigmentation, hollows and shadows properly, then talk through what we can improve, what we probably can’t and whether treatment is actually worth doing.
