What it is
Hexapeptide that acts as a competitive antagonist of α-MSH (alpha-melanocyte-stimulating hormone) at the MC1R receptor on melanocytes, reducing cyclic AMP-mediated induction of tyrosinase and MITF; the mechanism is upstream of tyrosinase inhibitors such as kojic acid or arbutin, targeting the transcriptional pathway before enzyme synthesis; may complement downstream tyrosinase inhibitors in a multi-pathway brightening regimen; peptide approach reduces the risk of irritation seen with some small-molecule brighteners.
When to use it
Mornings suit it best.
Where it sits
Serums sit after toner and before moisturiser. Thinnest to thickest, water before oil.
