A guide to why pigmentation happens, why it lingers, and what actually changes it on Black and Brown skin tones.
Dark spots on melanin-rich skin are usually post-inflammatory hyperpigmentation — extra pigment produced in response to irritation, which remains after the original breakout or injury has healed. They are not scars, they are not permanent, and they are not a sign that something is wrong with your skin. They are a sign your skin is doing exactly what melanin-rich skin does.
That's the short version. The rest of this guide is everything underneath it.
Why do I get dark spots when other people just go red?
Because redness and pigment are two different responses to the same thing.
When skin is irritated — by a breakout, a scratch, a harsh product, the sun — it inflames. On lighter skin, that inflammation shows up as redness, which fades as the inflammation settles.
On melanin-rich skin, inflammation triggers melanocytes, the cells that produce pigment. They release melanin into the surrounding tissue as a protective response.
The redness fades in both cases. The pigment doesn't.
So you and someone with lighter skin can use the identical product, have the identical reaction, and end up with completely different outcomes. Hers is gone in three days. Yours is there in March.
What is post-inflammatory hyperpigmentation?
PIH is pigment left behind after inflammation. It's flat — if you run a finger over it, you feel nothing. It appears exactly where the original irritation was, which is why acne marks sit in the shape of old breakouts.
It is the most common form of pigmentation on melanin-rich skin, and the most treatable.
Is it a scar?
Almost certainly not.
A scar is textural. It changes the surface of the skin — indented, raised, or a different texture to what's around it. That's tissue damage, and topical products can't undo it.
PIH is flat. It's a colour difference, not a texture difference.
The finger test tells you which you have. Close your eyes and run a fingertip over the mark. If you can't feel where it starts and stops, it's pigment, and pigment fades.
Then why hasn't mine faded?
Three common reasons.
You're still making new ones. If the thing causing the inflammation is still happening — ongoing breakouts, a product that irritates, daily sun exposure — you're producing pigment at the same rate you're fading it. The marks look permanent because they're being replaced.
You're not protecting it. UV exposure actively re-darkens existing marks. Every unprotected day undoes work.
It hasn't been long enough. Which is its own question.
How long does it actually take?
Longer than anyone selling you something wants to say.
Pigment sits at different depths. Surface pigment — recent marks, in the upper layers — clears faster. Deeper pigment takes considerably longer because the skin has to turn over, and turnover slows as you age.
Realistic timelines with consistent use and daily SPF:
Newer marks, a few weeks old: six to twelve weeks before you see meaningful change.
Established marks, months or years old: three to six months, sometimes longer.
If a product promises visible results in fourteen days, it's either describing surface hydration, or it's using something aggressive enough to cause the next problem.
Why does it look worse before it looks better?
Usually it doesn't — but two things can make it seem that way.
If you've started an active that's irritating your skin, you may be creating new pigment while fading old pigment. That's not purging. That's a reaction, and it's a reason to stop.
The other is that you're looking more closely than you were. Once you start treating something, you notice it daily. Marks you'd stopped seeing become visible again.
Photographs in the same light, a month apart, are more reliable than the mirror.
Is it melasma or is it PIH?
They look similar and they behave completely differently, which is why treating one as the other wastes months.
PIH appears where something happened — a spot, a cut, a reaction. The marks are scattered and irregular because breakouts are scattered and irregular. It responds well to consistent topical treatment.
Melasma is hormonal, usually triggered or worsened by sun and heat. It appears in symmetrical patches — both cheeks, the forehead, above the upper lip. It gets darker in summer, lighter in winter, and it's genuinely stubborn. It often needs more than topicals.
The clearest tell is symmetry. PIH doesn't match from one side of your face to the other. Melasma usually does.
If you've been treating symmetrical patches with a dark spot serum for a year and nothing's moved, that's worth knowing.
What about the marks around my mouth?
Perioral hyperpigmentation has several causes and they often overlap.
Friction. Lip products. Toothpaste — sodium lauryl sulfate and some flavouring agents are common irritants for this exact area. Hormonal pigmentation, which presents as a symmetrical shadow above the lip. And genetics, which plays a role independent of any of the above.
If you've ruled out the obvious and it's still there, the toothpaste is worth switching before anything else. It's cheap to test and it's more often the answer than people expect.
And my underarms, knees, elbows?
Body pigmentation often isn't the same process as facial PIH.
Repeated friction — shaving, clothing, resting on your elbows — causes chronic low-grade inflammation, and chronic inflammation produces persistent pigment. Some underarm and neck darkening is acanthosis nigricans, which is associated with insulin resistance and hormonal factors rather than irritation alone.
It also fades more slowly than facial pigmentation, because the skin is thicker and product doesn't penetrate as readily.
Does sunscreen actually matter if I have deep skin?
Yes, and more than for anyone else, for the specific issue of pigmentation.
Melanin gives some baseline UV protection — estimates vary but it's roughly equivalent to a low SPF. That is protection against burning. It is not protection against pigment.
UV exposure stimulates melanocytes directly. For skin that already overproduces pigment in response to triggers, sun is a daily trigger.
Treating dark spots without daily SPF is filling a bath with the plug out.
Do I need SPF indoors?
UVA passes through window glass. UVB largely doesn't.
UVA is the one implicated in pigmentation. So if you sit near a window, drive regularly, or work in daylight, yes.
What makes dark spots worse?
Anything that causes inflammation. The list is longer than most people expect.
Picking. Scrubs and physical exfoliants. Over-exfoliating with acids. High-strength actives introduced too fast. Fragrance, in anything. Heat — hot water, steam, cooking over a stove, hot climates. Friction, including from masks and clothing. Hair removal. Sun. And any product your skin is quietly reacting to without visible redness.
That last one is the most common. On melanin-rich skin, irritation doesn't always announce itself. Tightness, warmth, or a mark that appears a week later are often the only signals.
What about picking? Is it really that bad?
Yes, and it's the single most controllable factor.
Picking a spot turns a short inflammatory event into a prolonged one, and adds physical trauma on top. A breakout left alone might leave a faint mark for six weeks. The same breakout picked might leave one for six months.
This is unsatisfying advice because the urge is real and the spot is right there. But if you change one behaviour, change this one.
What ingredients actually work?
The ones that interrupt pigment production without causing the inflammation that creates more of it.
Alpha arbutin reduces the enzyme activity that produces melanin. Gentle, well tolerated, slow.
Niacinamide reduces pigment transfer to the surface and supports the barrier at the same time.
3-O-ethyl ascorbic acid is a stabilised vitamin C derivative. Vitamin C is genuinely effective; the problem is that pure L-ascorbic acid is unstable, oxidises, and irritates. Stabilised forms work without that.
Glutathione works on the pathway that determines which type of melanin is produced.
Azelaic acid is both anti-inflammatory and pigment-inhibiting, which is a useful combination for acne-related marks.
Nothing on this list works in a fortnight. Everything on this list works over months.
What should I be careful with?
Hydroquinone is effective and regulated for a reason. Long-term unsupervised use can cause ochronosis — a permanent blue-grey darkening that is far harder to treat than what you started with. If used, it should be short courses with medical oversight.
High-strength acid peels, particularly on melanin-rich skin, carry a real risk of causing the exact pigmentation you're treating. Depth matters enormously and so does who's performing it.
Retinoids are effective but need slow introduction. Too much too fast causes irritation, and irritation causes pigment.
Anything marketed as lightening, whitening or brightening your complexion. Fading a dark spot and lightening your skin are different goals, and products designed for the second often achieve it by being aggressive enough to damage.
Can I use more than one active at once?
You can, eventually. Not at the start.
The problem with layering several actives immediately is that if your skin reacts, you have no idea which one did it. You end up eliminating things at random.
One at a time, two to three weeks apart, is slower and tells you far more.
Does a 10-step routine help?
No. And it often makes things worse.
Every additional product is another chance to irritate. For skin that converts irritation into pigment, a long routine is a lot of opportunities for something to go wrong, and no way to identify which product is the problem.
Cleanse, treat, protect. Consistently. That's the routine that works.
Why did a product that works for everyone else make my skin worse?
Because most products were developed and tested on skin that doesn't respond to irritation the way yours does.
Clinical testing has historically under-represented darker skin tones. A formulation can be genuinely well tested, genuinely effective, and still have been optimised for a response pattern that isn't yours.
This is the part worth sitting with: when a product fails on your skin, the default explanation offered is that your skin is sensitive, difficult, or reactive.
Your skin isn't sensitive. It's specific. And it was behaving exactly as it's supposed to.
Will my dark spots ever fully go?
Most PIH fades substantially with consistent treatment and sun protection. Some marks fade completely. Older, deeper pigmentation may lighten considerably without disappearing entirely.
Melasma is manageable rather than curable — it tends to improve and return with hormonal and seasonal cycles.
What changes most for people isn't usually total clearance. It's that new marks stop appearing, existing ones lighten, and the thing stops governing how they feel about their face.
Where do I start?
Stop the inflammation. Then treat the pigment. Then protect it daily, without exception.
In that order. Most people do it in reverse and wonder why nothing holds.
VOUEE formulates in Seoul specifically for melanin-rich skin. Our Correct & Boost serum uses alpha arbutin, 3-O-ethyl ascorbic acid, glutathione and niacinamide, at concentrations intended to fade pigment without triggering it.
