Dark marks are the number one cosmetic complaint we hear, and the number one reason people damage their skin trying to fix it themselves. The lightening creams sold in every corner shop in Nairobi are, for the most part, unregulated mixtures containing potent steroids, hydroquinone at unsafe concentrations, or mercury. They produce a brief improvement followed by thinned skin, stretch marks, steroid acne, permanent broken blood vessels and rebound pigmentation that is worse than what you started with.

Pigmentation is treatable – properly, safely and without bleaching your skin. It just takes a diagnosis and some patience.

What kind of pigmentation do you have?

They look similar and behave completely differently:

Type Typical appearance Key factor
Post-inflammatory hyperpigmentation Flat brown or grey marks exactly where a spot, cut, burn or rash was Treat the underlying inflammation first
Melasma Symmetrical brownish patches on cheeks, forehead, upper lip and jawline Hormones and sun; chronic and relapsing
Solar lentigines Well-defined spots on sun-exposed skin Cumulative UV
Exogenous ochronosis Blue-black, mottled pigment where lightening creams were used Caused by misuse of skin lightening products
Periorbital hyperpigmentation Dark circles under and around the eyes Often genetic, allergic or structural rather than pigment alone
Acanthosis nigricans Velvety dark thickening in the neck, armpits and groin Often linked to insulin resistance – needs medical workup
Pigmented contact dermatitis Pigmentation following use of a cosmetic or fragrance Identify and remove the culprit

Some of these are a sign of something systemic. Acanthosis nigricans, in particular, is often the first visible clue to insulin resistance or diabetes, and is worth investigating rather than just treating cosmetically.

Why pigmentation is harder to treat at the equator

Nairobi sits almost exactly on the equator at around 1,795 metres. Both facts increase UV exposure – the sun is close to overhead year-round, and there is less atmosphere above you to filter it. UV is the single biggest driver of melasma relapse and of post-inflammatory marks re-darkening after they have been treated.

This is why daily broad-spectrum sunscreen is not optional in any pigmentation plan. Without it, you are treating and re-triggering at the same time. A tinted sunscreen with iron oxides is particularly useful for melasma because it also blocks visible light, which drives pigmentation in darker skin types.

How we treat hyperpigmentation

1. Diagnose and stop the cause

There is no point fading marks while acne, eczema or a contact allergy keeps producing new ones. Active acne, dermatitis or infection is treated first. Any lightening creams and unprescribed steroids are stopped under supervision, since abrupt withdrawal can cause a rebound flare.

2. Prescription topical therapy

A supervised regimen may include tyrosinase inhibitors, retinoids, azelaic acid, kojic acid, niacinamide, tranexamic acid preparations and, where genuinely appropriate, short supervised courses of hydroquinone – which is a legitimate medical treatment when used correctly for a limited period, and a disaster when bought over the counter and used indefinitely.

3. Sun protection, non-negotiable

Broad-spectrum SPF 30-50 every morning, reapplied if you are outdoors, plus hats and shade. Tinted formulations for melasma.

4. In-clinic procedures

Once the skin is prepared and calm, superficial chemical peels speed up pigment clearance, and microneedling can help selected cases – always at conservative settings on darker skin, because the wrong parameters cause pigmentation rather than clearing it.

5. Maintenance

Melasma in particular is a chronic, relapsing condition. Long-term maintenance therapy plus sun protection is what keeps it away, and stopping everything the moment it clears is the reason it comes back every year.

How long does it take?

  • Post-inflammatory hyperpigmentation: visible improvement from 8-12 weeks, substantial fading by 4-6 months. Deeper (dermal) pigment takes longer.
  • Melasma: improvement over 3-6 months with a good regimen, and lifelong maintenance to hold it.
  • Solar lentigines: respond well to targeted treatment.
  • Exogenous ochronosis: slow and difficult – prevention by avoiding the products is far better than cure.

If a product promises to lighten your skin in two weeks, it either contains a potent steroid, a banned agent, or both. Ask what is in it before you put it on your face.

Which kind of pigmentation is it?

Pigmentation is not one condition, and the single commonest reason treatment fails in Nairobi is that a patient with one type was given a plan designed for another. Telling them apart is the whole game.

Type How it usually looks What it responds to
Post-inflammatory Flat marks exactly where a spot, bite or rash used to be Treat the cause first; the marks then fade, though slowly
Melasma Symmetrical patches on cheeks, forehead or upper lip; darkens in sun Long-term control rather than cure – prescription therapy plus rigorous sun protection
Sun-related Scattered darker spots on face, hands and forearms Sun protection plus targeted treatment
Steroid or lightening-cream damage Uneven tone with thin skin, visible vessels, sometimes rebound darkening Managed withdrawal first, then repair – never abrupt stopping
Ochronosis Blue-grey discolouration after long-term high-strength hydroquinone Stopping the product; genuinely difficult to reverse, which is why prevention matters

Why the equator makes this harder

Nairobi sits almost on the equator at roughly 1,795 metres, so UV is high all year rather than seasonal. There is no winter in which pigmentation quietly settles. Every treatment you pay for is in a continuous tug-of-war with daily light exposure, and that is why sun protection is not the optional last line of a treatment plan here – it is the foundation of it.

A realistic timeline

  1. Weeks 1-4: preparation and settling the skin. Often no visible change, and this is where people quit.
  2. Months 2-3: the first honest signs – marks softening at the edges, tone evening slightly.
  3. Months 4-6: the change other people start to notice.
  4. Beyond: maintenance. Melasma in particular returns when treatment stops completely.

Checklist before you start

  • Bring every product you have used, especially anything bought from a market stall or sent from abroad
  • Do not stop a lightening cream abruptly the week before your appointment – abrupt withdrawal causes a rebound flare, and it is managed properly alongside treatment
  • Bring photographs from a year ago if you have them, so we can see the direction of travel
  • Be ready to commit to daily sun protection. Without it, the rest is wasted money

Where pigment sits alongside scarring or texture change, microneedling and chemical peels may be added, but always after the pigment itself is under control.

Hyperpigmentation & melasma in Nairobi – questions patients ask

How much does melasma treatment cost in Nairobi?

Costs vary with the regimen and whether peels are included. Fees are quoted at or before the consultation. Note that melasma treatment is ongoing rather than a one-off, so we will plan around a budget you can sustain. Call 0728 566990.

Are skin lightening creams dangerous?

The unregulated ones are, yes. Potent steroids, high-strength hydroquinone and mercury are all found in creams sold openly in Nairobi, and they cause thinning, stretch marks, steroid acne, ochronosis and rebound darkening. Hydroquinone used correctly under supervision for a limited period is a different matter.

Will my dark marks come back?

Post-inflammatory marks will not return if the underlying condition stays controlled and you use sunscreen. Melasma is relapsing by nature and needs maintenance.

Do I need to wear sunscreen indoors?

If you sit near a window or spend a lot of time in front of screens, a tinted sunscreen is worth it – visible light also drives pigmentation in darker skin. For most people the priority is simply applying it every morning before leaving the house.

Can chemical peels lighten my skin?

Medical peels even out tone and clear excess pigment; they do not and should not bleach your natural complexion. On darker skin, peels must be chosen conservatively – see chemical peels.

What about dark underarms, neck and groin?

Common causes include friction, shaving, deodorant irritation, chronic dermatitis and acanthosis nigricans linked to insulin resistance. Treatment depends on which one it is, so it is worth having it examined rather than treated blindly.

Why pigmentation takes patience

Pigmentation is the most common reason people come to this clinic, and the most common reason they leave disappointed elsewhere. The reason is nearly always the same: expectations set to weeks when the biology runs in months.

Pigment sits at different depths. Marks left after a spot or an insect bite are usually superficial and fade reasonably predictably. Melasma sits deeper, is driven by hormones and light as much as by anything you apply, and behaves less like a stain to be removed than like a condition to be controlled. Treating both the same way is why so many courses stall.

What actually shifts it

  • Treating the cause first. Pigment that follows acne, eczema or a fungal rash will keep being replenished until the underlying problem is controlled.
  • Prescription topicals used consistently, for months rather than weeks, and stepped down rather than stopped abruptly.
  • Daily sun protection. This is not the optional extra at the end of the plan – it is the plan. Without it, everything else is undone continuously.
  • Procedures where appropriate, chosen for your skin type and always after preparation.
  • Maintenance. Melasma returns when treatment stops entirely. Long-term low-level maintenance is what keeps it clear.

What we will not do

We do not use the unregulated lightening products sold openly around Nairobi, and we do not lighten your natural complexion. The goal is even tone – clearing the excess pigment that does not belong there while leaving the colour that does.

Those products deserve a plain warning. Many contain potent steroids, unsafe concentrations of hydroquinone, or mercury compounds. They produce thinning skin, visible vessels, stretch marks, steroid acne, and a rebound darkening on stopping that is frequently worse than the pigmentation that prompted them. Long-term high-strength hydroquinone can also cause ochronosis, a stubborn blue-grey discolouration that is considerably harder to treat than the original problem. If you are using something already, bring it in rather than stopping overnight – abrupt withdrawal after months of use causes a flare of its own, and it is managed alongside whatever replaces it.

Can I use lemon, turmeric or toothpaste on dark marks?

Please do not. Lemon juice on skin exposed to sun can cause a genuine chemical burn and leave far worse pigmentation than you started with. Home remedies are the origin of a meaningful share of the pigmentation we treat.

Is melasma related to pregnancy or contraception?

Frequently, yes. Hormonal change is one of the main drivers, which is why melasma often appears in pregnancy or after starting hormonal contraception. It does not always resolve on its own afterwards, and it is still treatable either way.

Will my skin get lighter than my natural colour?

No, and that is not the goal. Treatment clears the excess pigment that does not belong there so your tone becomes even. Your natural complexion stays your natural complexion.

Do I need sunscreen if I am indoors most of the day?

Yes, if you are near windows or spend any part of the day outside. Visible light and UVA both reach through glass and both contribute to melasma, which is one reason melasma can persist in people who feel they are rarely in the sun.
