Melasma fades fastest when treated in winter and protected all year. Tranexamic acid, niacinamide, gentle in-clinic care and the SPF habit explained.
Short answer: Melasma is managed rather than cured: it fades with treatment and returns with sun, heat and hormones. Winter is the best time to treat it because triggers are lowest. Combine a gentle brightening serum, such as tranexamic acid or niacinamide, with a tinted sunscreen every day, all year, to stop it coming back.

If brown patches appear on your cheeks, forehead or upper lip every summer, fade a little in winter and return with the first warm days, you are probably dealing with melasma. It is one of the most frustrating skin concerns because it keeps coming back. This guide explains why, and how to use the winter months to get ahead of it. For other types of pigmentation, see our guide to dark spots and uneven tone.
What melasma is
Melasma is a pattern of brown or grey-brown patches, usually on both cheeks, the forehead, the bridge of the nose or the upper lip. It is much more common in women and in medium to darker skin tones. The main triggers are sunlight, heat, visible light from the sun, and hormones, which is why it often starts in pregnancy or with some contraceptives. Genes play a part too.
Melasma or dark spots?
| Feature | Melasma | Sun spots / post-acne marks |
|---|---|---|
| Shape | Larger patches, often symmetrical on both sides | Small, separate spots |
| Trigger | Sun, heat, visible light, hormones | Sun damage or a healed pimple |
| Behaviour | Fades and returns with seasons | Fades slowly and stays faded with SPF |
| Approach | Gentle, long-term, strict sun protection | Brightening actives and SPF |
Why winter is your window
Kabul's strong sun and summer heat keep re-triggering melasma, so treatments started in summer are fighting a losing battle. In winter, sun exposure is lowest and skin is covered more. Brightening ingredients then have a chance to work without the patches being darkened again every day, and gentle in-clinic treatments carry less risk.
A winter melasma routine
1. Morning: gentle cleanse and a brightening serum
Wash with a mild cleanser, then apply a serum with tranexamic acid or niacinamide to the whole face, not only the patches. Our tranexamic acid serum combines tranexamic acid with niacinamide to target stubborn pigment pathways gently.
2. Morning: moisturise
Use a simple moisturiser so the skin barrier stays calm; irritated skin can trigger pigment production and darken further.
3. Morning: tinted sunscreen, every day
Apply a broad-spectrum sunscreen, ideally tinted with iron oxides, and reapply if you are outdoors. This is the single most critical step that stops relapse. For daily protection, choose a gentle daily sunscreen and wear a tinted layer over it.
4. Evening: treat
Two or three evenings a week, use a targeted brightening active such as azelaic acid or a kojic brightening serum, or a gentle retinal if your skin tolerates it. Do not stack multiple strong actives on the same night.
5. Review after 8–12 weeks
Melasma fades gradually over cell turnover cycles. Take a photo in the same light every month and review with a specialist before switching products.
What to avoid
- Bleaching or "whitening" creams of unknown origin: Some street creams contain strong unlisted corticosteroids or toxic mercury, which thin the skin and cause permanent rebound pigmentation.
- Harsh scrubs and aggressive chemical peels: Friction and thermal irritation can trigger inflammatory pigment and make melasma darker.
- Skipping sunscreen on cloudy or smoggy days: Harmful UVA rays and high-energy visible light penetrate winter clouds and windows.
- Direct intense heat: Prolonged hot baths, saunas and standing over hot stoves can stimulate pigment-producing cells in heat-reactive skin.
In-clinic help
If home care is not enough after two to three months, a specialist can add gentle in-clinic brightening treatments. For stubborn melasma, a dermatologist may prescribe specialized medical formulations. Avoid aggressive laser treatments that generate heat, which can trigger severe melasma rebound.
Key points
- Melasma is triggered by sun, heat, visible light and hormones, and often returns.
- Winter is the ideal window to begin treatment when UV radiation is lowest.
- Gentle actives such as tranexamic acid, niacinamide and azelaic acid work over months.
- Tinted sunscreen with iron oxides every single day is essential to prevent relapse.
- Always check with a doctor before using active ingredients during pregnancy or while breastfeeding.
Frequently asked questions
What is the best way to treat melasma?
The best results come from combining daily broad-spectrum sun protection (ideally a tinted mineral sunscreen with iron oxides) with gentle brightening ingredients such as tranexamic acid, niacinamide or azelaic acid, used consistently for several months.
Can melasma be cured permanently?
Melasma can be faded substantially, but because melanocytes remain sensitive to sun, heat and hormonal shifts, it often recurs. Most people manage it successfully long-term with daily sunscreen and a gentle maintenance routine.
Why is winter the best time to treat melasma?
In winter, sunlight and heat levels are lower, so treatment is not constantly undone by daily UV exposure. Gentle exfoliating and brightening treatments carry much lower risk of post-inflammatory hyperpigmentation.
Does tranexamic acid work for melasma?
Yes. Topical tranexamic acid inhibits melanin synthesis pathways and helps lighten stubborn melasma patches over weeks to months, particularly when paired with niacinamide and strict sun protection.
Is melasma caused by pregnancy?
Hormonal fluctuations during pregnancy often trigger melasma (frequently called the "mask of pregnancy"). Contraceptive pills can have a similar effect. Always consult a physician before using active skincare products while pregnant or nursing.
