Science
Mechanism of Action
This peptide operates by modulating inflammatory responses through its interaction with the melanocortin 1 receptor (MC1-R). By inhibiting the binding of α-melanocyte-stimulating hormone (α-MSH) to MC1-R, it effectively reduces the release of key inflammatory cytokines, such as IL-8 induced by UVB radiation and IL-1α. This action not only diminishes redness and swelling but also mitigates neurogenic edema and adverse effects associated with substance P release, providing significant soothing benefits to the skin.
