Hyperpigmentation is a common skin concern where certain areas become darker than the surrounding skin due to excess melanin production.
It may appear as:
- Sun spots or age spots
- Uneven skin tone
- Dark marks following acne
- Pigmented patches on the face or body
One particular type of pigmentation, known as melasma, is triggered by hormones and commonly develops during pregnancy or whilst taking hormonal contraception. Melasma often appears as symmetrical brown patches across the cheeks, forehead or upper lip.
Although pigmentation is harmless, it can take months or even years to fade without treatment.
