Pigment, tone & photoprotection
One of 5 mechanistic pathways to ✨ Skin, hair & aesthetics · 13 options
UV is responsible for the large majority of visible facial ageing. Nothing in this pathway replaces sunscreen — they raise the threshold at which damage happens and address pigment that already exists.
Melasma is frequently hormonal, and thyroid disease causes pigment change directly. Worth ruling out before spending months on topicals.

What engages this pathway
Ordered by how directly each one acts on the mechanism above — never by how much trial evidence exists. Each links to its full breakdown with dosing, half-life and vendor.
💉 Melanotan 1
Afamelanotide — an MC1R agonist that increases eumelanin, and it is actually approved for erythropoietic protoporphyria. Photoprotection through your own pigment. The melanoma-surveillance concern is that it darkens existing naevi and can mask change.
💉 Melanotan 2
Non-selective melanocortin agonism — tanning plus libido plus nausea plus mole darkening. Less targeted than MT-1 in every direction.
💉 Glutathione
Inhibits tyrosinase and shifts melanin synthesis from eumelanin toward pheomelanin, which is the basis of the skin-lightening use across Asia. IV use for cosmetic lightening has documented safety incidents and is not an approved indication.
💉 Decapeptide-12
A tyrosinase inhibitor with topical trial data for melasma — targeted at pigment production rather than bleaching existing pigment.
💉 Tretinoin
Accelerates turnover of pigmented keratinocytes; standard in melasma protocols.
🧬 Polypodium Leucotomos
Oral fern extract that raises the minimal erythema dose measurably in controlled human studies — real systemic photoprotection, and useful where sunscreen cannot reach or be reapplied.
🧬 Astaxanthin
Trials show reduced UV-induced skin damage and improved elasticity. Also crosses into skin lipid membranes effectively.
🧬 Niacinamide
Oral nicotinamide reduced new non-melanoma skin cancers by 23% in the ONTRAC randomised trial — one of the most concrete results on this page. Topically it also reduces pigment transfer to keratinocytes.
🧬 Lutein & Zeaxanthin
Accumulates in skin as well as retina, with trials showing improved skin hydration and photoprotection.
🧬 Vitamin C
Regenerates vitamin E and limits UV-induced oxidative damage, on top of the collagen role.
🧬 Vitamin E
Lipid-phase protection in the cell membrane; synergistic with C, which recycles it.
🧬 Grape Seed Extract
Proanthocyanidins with trial data for melasma improvement.
🧬 Pycnogenol
Improved melasma area and skin hydration in trials, plus a photoprotective effect.

Frequently asked questions
UV is responsible for the large majority of visible facial ageing. Nothing in this pathway replaces sunscreen — they raise the threshold at which damage happens and address pigment that already exists.
13 options are mapped to this pathway in the Vault, including Melanotan 1, Melanotan 2, Glutathione, Decapeptide-12. They are grouped by the mechanism they act through rather than ranked by how much trial evidence exists — 11 carry clinical validation and 2 are mechanistic predictions.
Melasma is frequently hormonal, and thyroid disease causes pigment change directly. Worth ruling out before spending months on topicals. The markers worth checking are TSH (Thyroid-Stimulating Hormone), Vitamin D (25-Hydroxy), Ferritin, Comprehensive Metabolic Panel (CMP).
Unproven is not the same as ineffective. Of the 13 options on this pathway, 11 have clinical validation and 2 are graded theoretical — meaning the mechanism is sound but the specific human trial has not been run, which is true of a great deal of what works in this space. Nothing on this page is ordered by evidence tier, because sorting by trial count would bury the compounds you came looking for.
