Research Overview
Beta-MSH
Beta-MSH is one of the endogenous melanocortin peptides studied for its ability to influence melanin synthesis. Most evidence is mechanistic, focusing on receptor signaling and melanocyte biology rather than cosmetic use.
Matrixyl Synthe'6
Palmitoyl tripeptide-38 has a mix of published cosmetic research and formulation data suggesting benefits for skin appearance and matrix-support signaling. Its practical use is as a topical anti-aging ingredient in combination with hydrators and barrier-support agents.
