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.

Argireline

Acetyl hexapeptide-3 has both in vitro and small human-cosmetic studies supporting a reduction in wrinkle depth or wrinkle appearance. Its best-supported role is as a topical cosmetic peptide rather than a systemic drug.
