Melasma
It often appears as symmetrical patches on the cheeks, forehead or upper lip. It needs strict, ongoing protection from sunlight and visible light and may require a dermatologist-led plan.
Post-inflammatory and acne marks
Controlling active acne and avoiding picking reduces new marks. Dark-spot ingredients are more useful when introduced gradually with moisturiser and sunscreen.
Protection comes first
Choose broad-spectrum SPF 30 or higher, apply enough and reapply during exposure. Tinted sunscreen containing iron oxides may help protect against visible light for people prone to pigmentation.
