Melasma is the one that appears in your late twenties or during pregnancy: symmetrical brown or greyish patches across the cheeks, forehead, upper lip and jawline. Not spots — patches, usually mirrored on both sides of the face.
It is also the most misunderstood pigmentation problem, and the one where the usual “just use a strong brightening cream” advice does the most damage.
What causes it
Melasma needs two ingredients together: hormones and UV. Either alone is usually not enough.
Hormonal triggers include pregnancy (where it is common enough to be nicknamed the mask of pregnancy), hormonal contraception, and hormone therapy. Some people develop it with no clear hormonal trigger at all, and there is a strong genetic component — if your mother had it, your risk is higher.
UV is the accelerant. This is where Kenya matters: equatorial sun, high altitude in Nairobi and the highlands, year-round intensity with no low-UV season. Melasma that might stay mild elsewhere becomes far more visible here.
The part most people miss: visible light
Melasma is triggered not only by UV but by visible light — ordinary light you can see. This is important and rarely mentioned, because SPF ratings measure only UV protection. A sunscreen can have SPF 50 and offer nothing against visible light.
The practical answer is tinted sunscreen. Iron oxide pigments — the ones used to prevent white cast on deeper skin — also help block visible light. For melasma specifically, a tinted sunscreen genuinely outperforms an untinted one of the same SPF.
Manage, not cure
This is the honest framing, and it is better to have it upfront than to be disappointed at month four.
Melasma is a chronic, relapsing condition. It improves substantially with the right care and it flares back with sun exposure, pregnancy, or a hormonal change. People who get it under control keep it under control by continuing to protect their skin — not by finishing a course of treatment and stopping.
That is not a reason to despair. Well-managed melasma can become barely visible. It just does not stay that way on its own.
What helps
Sun protection is 80% of the answer
If you do nothing else, do this. Melasma without rigorous daily sun protection does not improve, regardless of what you put on top of it.
- Tinted SPF 50, broad spectrum, every single morning.
- Two finger-lengths for face and neck — under-application is the norm.
- Reapply every 2–3 hours outdoors or driving. Car windows pass a lot of UVA, and melasma is often noticeably worse on the driver's side of the face.
- A wide-brimmed hat for genuinely sunny days. Shade is a real tool, not a consolation prize.
Gentle brightening actives
Tranexamic acid is the standout here. It is one of the most-researched newer options for melasma specifically, works on the pigment pathway rather than bleaching, and is gentle enough for the long-term daily use melasma requires.
Niacinamide supports an even tone and strengthens the barrier — useful, because melasma-prone skin is often reactive.
Vitamin C adds antioxidant support and helps with overall tone.
Gentleness is a treatment, not a compromise
Melasma responds badly to aggression. Harsh scrubs, strong peels, and stacking multiple potent actives cause inflammation, and inflammation makes melasma worse. Many people make real progress simply by stopping everything harsh and being consistent with sunscreen and one gentle active.
What to avoid
- Mercury-containing lightening creams — illegal in cosmetics in Kenya, still circulating, and causing kidney and neurological damage.
- Unlabelled steroid creams — thin the skin and cause a severe rebound worse than the original melasma.
- Long-term high-strength hydroquinone — risks exogenous ochronosis, a permanent blue-black darkening. If used at all, it should be short supervised courses.
- Aggressive scrubs and DIY acid treatments — the inflammation drives the melasma.
- Anything promising results in days — melasma does not work that way, so whatever is producing that result is not something you want on your face.
Pregnancy
Melasma frequently appears during pregnancy and often improves in the months after delivery, though not always completely.
Please check with your doctor or midwife before using any active ingredient while pregnant or breastfeeding. Be sceptical of products marketed as “pregnancy-safe” — many popular ingredients carry that label based on marketing rather than clinical safety testing in pregnancy. Sun protection, which is unambiguously safe, is also the most effective thing you can do during this period.
When to see a dermatologist
Melasma is one of the conditions where professional input genuinely helps. See a dermatologist if it is spreading, if six months of consistent care has not helped, if you want to discuss prescription options, or if you are considering peels or laser — some laser treatments make melasma dramatically worse on deeper skin, so it needs someone experienced with your skin type.
The short version
Melasma is hormones plus light, and Kenya supplies a lot of light. Tinted SPF 50 every morning is the foundation. Add a gentle brightening active like tranexamic acid, avoid anything harsh, and expect to manage it long term rather than cure it. Consistency, shade and patience outperform anything aggressive.
