Hyperpigmentation Reduction
Even skin tone through melanin regulation.
TL;DR
Daily broad-spectrum sunscreen is non-negotiable, because UV drives every form of pigmentation. Topical vitamin C and niacinamide help; oral supplements play a supporting role at best.
Why It Matters
Melasma, post-inflammatory hyperpigmentation and solar lentigines have different drivers and prognoses. Post-inflammatory pigmentation fades over months; melasma is hormonally influenced and relapses readily without sun protection.

Biomarkers
Optimization Protocol
Apply broad-spectrum SPF 30 or higher every morning, reapplying when outdoors, and prefer tinted mineral formulations which also block visible light in melasma. Use topical vitamin C in the morning and niacinamide or a retinoid at night. Treat the underlying inflammation in post-inflammatory pigmentation and avoid picking. Expect three to six months for visible change.
Supporting Supplements
Astaxanthin
Oral astaxanthin may slightly reduce UV-driven pigmentation but the evidence base is small and industry-funded.
Vitamin C
Topical vitamin C brightens pigmentation modestly; oral vitamin C does not.
Niacinamide
Topical niacinamide reduces pigmentation with good tolerability, making it a sensible first step in sensitive skin.
