Research Overview
Tetracosactide
Tetracosactide is the synthetic ACTH(1-24) fragment and is commonly used to probe melanocortin receptor signaling. Its melanogenic relevance comes from the same N-terminal motif that drives ACTH-related pigmentation effects.
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.
