Rigin

A palmitoylated tetrapeptide examined in skincare research for its influence on inflammatory signaling associated with skin aging.

In the literature, Rigin appears most often in work focused on anti-aging, skin health and inflammation. Studies in this area tend to look at mechanisms and observed effects in laboratory and preclinical settings rather than outcomes in people, so the picture is best read as a map of where researchers have been curious — not as evidence of any benefit.

Rigin is catalogued here under powder peptides. Coverage of this compound varies in quality and depth, and much of it remains early-stage. Reading the underlying research directly is the only way to judge how strong any particular finding is.
