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.

Hexapeptide-9 appears in scientific and cosmetic literature related to wound repair, cell migration, and extracellular matrix support. The evidence base is smaller than for more established peptides, but it is a real research-backed cosmetic ingredient.
