Hyperpigmentation — dark spots, melasma, post-inflammatory marks — is one of the most searched skincare concerns, and one of the most poorly addressed. The most common mistake is reaching for a single brightening product and expecting dramatic results. Effective treatment requires a multi-pathway approach: targeting melanin production, inhibiting its transfer to skin cells, accelerating clearance of pigmented cells, and — critically — blocking the UV stimulus that continuously triggers new melanin formation.
The most effective approach combines tyrosinase inhibitors (vitamin C, niacinamide, azelaic acid) with exfoliants that clear already-pigmented cells (AHAs) and daily SPF that prevents new melanin forming in response to UV. No single ingredient is sufficient — the multi-pathway approach produces results that individual actives cannot match alone.
Without SPF 50 every morning, UV exposure partially reverses each night's depigmenting progress the following day. Skipping SPF while treating hyperpigmentation is the equivalent of bailing a boat with the hole still open. SPF is not a supporting character in a hyperpigmentation routine — it is the lead intervention that makes everything else work.
Inhibits tyrosinase and prevents the oxidative reactions driving melanin production. Applied in the morning before SPF, the antioxidant effect also prevents UV-triggered melanogenesis that would otherwise re-darken spots daily.
Works downstream of melanin production by blocking transfer of melanin packages from melanocytes to skin cells. Studies show 5% niacinamide comparable to 4% hydroquinone for PIH in some trials, with a significantly better safety profile for long-term use.
Targets abnormally active melanocytes specifically, leaving normal ones largely unaffected. Pregnancy-safe, no photosensitivity, suitable for long-term daily use. Effective for both PIH and melasma.
Inhibits plasmin, which drives UV-stimulated melanocyte activation. Particularly well-evidenced for melasma. Minimal irritation. Increasingly available OTC in serums and toners.
Glycolic acid 5–10% used 2–3 nights per week accelerates shedding of already-pigmented cells. Exfoliants do not reduce new melanin production — they speed clearance of existing pigmentation, working alongside tyrosinase inhibitors rather than replacing them.
Cleanser → Vitamin C 15–20% → Niacinamide 5% → Moisturiser → SPF 50
Double cleanse → Glycolic acid 5–10% → Niacinamide → Ceramide moisturiser
Double cleanse → Azelaic acid 10–15% or tranexamic acid → Niacinamide → Ceramide moisturiser
Allow 12–16 weeks minimum before evaluating results. Melasma requires 6–12 months of consistent treatment. The darker and more established the pigmentation, the longer the timeline — but consistent application of this protocol produces meaningful results for almost all types.
