What it is

Mechanism of action
The peptide sequence is hypothesized to reduce inflammatory cytokine production and support skin barrier function. Topical application is intended to address chronic low-grade inflammation associated with photoaging.
Use as cosmetic ingredient
Formulated into topical anti-aging skincare products, typically combined with other peptides.
Why this is out of scope at The Tide
