What is ACTH?
A 39-amino-acid melanocortin peptide derived from POMC with documented melanogenic activity. In skin biology, ACTH is a classic signal for melanocyte stimulation and hyperpigmentation research.
Key Benefits & Mechanisms
Stimulates melanogenesis
Supports eumelanin production
Useful for pigmentation-pathway research
May model UV-response signaling
Research Summary
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.
