Research Overview

Eyeseryl

Acetyl tetrapeptide-5 has topical cosmetic literature and formulation studies focused on edema reduction and eye-contour improvement. It is mainly used for appearance benefits rather than as a systemic therapeutic peptide.

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.
