Science
Mechanism of Action
This tripeptide operates by upregulating the production of cyclic adenosine monophosphate (cAMP) within melanocytes. Elevated cAMP levels directly stimulate melanogenesis, the process by which melanin pigments are synthesized, leading to an accelerated and enhanced tanning response under UV exposure.
