Research Overview
ACTH
ACTH activates melanocortin receptors on melanocytes and can increase pigment synthesis. It is widely used as a reference peptide in studies of tanning, adrenal biology, and hyperpigmentation.
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.
