Vitamin A for hyperpigmentation.
Vitamin A for hyperpigmentation — what the science actually says, what concentration is therapeutic, and which products in the Uwazia catalog pair the two. Evidence grade: moderate.
What the evidence says
Moderate evidence.
Several studies support the claim, with some inconsistency in conditions or outcomes.
That's our honest grade — not a marketing claim.
The science
What's actually happening.
How vitamin a works
Converts to retinoic acid in skin; binds nuclear receptors to upregulate cell turnover, collagen production, and melanin regulation.
Full ingredient pageWhat hyperpigmentation is
Excess melanin deposition triggered by UV, inflammation, hormones, or trauma. Melanocytes upregulate tyrosinase production, depositing melanin in epidermis or dermis.
