Melanocortin Receptor Pharmacology As a non-selective melanocortin agonist, MT-II engages multiple receptor subtypes

The outermost layer of cells is continually sloughed off as new skin cells rise to the surface

On the other hand, peptides have a variety of effects, and may increase collagen, elastin, and glycoprotein production, thereby increasing skin thickness and elasticity

Contributes to improved energy levels and metabolism

As far as the other polymorphic genes are concerned (NRF2, HO-1, CAT, SOD), the examined studies do not allow to confirm for each a conclusive and causative role in vitiligo onset and progression
