Pigmentation is often treated as a single problem, but it's actually several different conditions that happen to look similar — dark or uneven patches on the skin. The cause matters enormously for choosing the right treatment, because what works for one type can actually worsen another.
Melasma, often triggered by hormonal changes (pregnancy, birth control, or hormonal fluctuations), tends to appear as larger, symmetrical patches, often on the cheeks and forehead. It's notoriously sensitive to aggressive treatment — overly intense peels or lasers can actually trigger more pigmentation rather than less, which is why a more cautious, gradual approach usually works best.
Sun-induced pigmentation (sometimes called sun spots or solar lentigines) responds well to a broader range of treatments including chemical peels and targeted laser therapy, since it sits more superficially in the skin compared to melasma.
Post-inflammatory hyperpigmentation — the dark marks left behind after acne heals — typically fades on its own over months but can be accelerated with the right combination of gentle exfoliation and brightening agents.
This is exactly why a proper assessment before treatment matters so much: applying the wrong intensity or type of treatment to melasma specifically can make pigmentation worse, not better. And regardless of the type being treated, daily sunscreen is non-negotiable — UV exposure is what triggers and worsens virtually every type of pigmentation.
