Research Overview
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.
Gamma-MSH
Gamma-MSH has been investigated as part of the broader melanocortin network that regulates pigmentation. Evidence suggests it can contribute to melanocyte signaling, though its cosmetic use remains experimental.
