    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.

    How to Measure

    Biomarkers

    Standardised photographs
    MASI score for melasma
    Sunscreen adherence
    Vitamin D (if sun avoidance is strict)

    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

    Compound
    Mixed evidence
    Preliminary

    Oral astaxanthin may slightly reduce UV-driven pigmentation but the evidence base is small and industry-funded.

    Vitamin C

    Vitamin
    Likely effective
    Moderate Evidence

    Topical vitamin C brightens pigmentation modestly; oral vitamin C does not.

    Niacinamide

    Vitamin
    Likely effective
    Moderate Evidence

    Topical niacinamide reduces pigmentation with good tolerability, making it a sensible first step in sensitive skin.

    Frequently Asked Questions

    What actually fades dark patches?
    Daily broad-spectrum sunscreen plus topical agents such as retinoids, azelaic acid, vitamin C or prescription hydroquinone under supervision. Progress takes 3-6 months.
    Do oral supplements help?
    Evidence is limited. Polypodium leucotomos at 240-480 mg/day and oral tranexamic acid under medical supervision have some melasma data; tranexamic acid carries clotting risk and is not self-prescribed.
    Does glutathione lighten skin?
    Oral absorption is poor and evidence is weak. Intravenous use for skin lightening is not recommended and has caused serious adverse events.
    Why does pigmentation keep returning?
    UV and visible light reactivate melanocytes, so sunscreen with iron oxides for visible light protection is essential to maintain any gains.
    Are hormones involved?
    Often in melasma - pregnancy and combined oral contraceptives are common triggers, which is worth reviewing with a clinician.
    When should a doctor look at a dark spot?
    Any lesion changing in size, shape or colour, bleeding, or looking different from surrounding marks should be assessed promptly.
