Progeline

Progeline is a synthetic tripeptide developed to combat skin aging by targeting progerin, a protein associated with accelerated aging. Researchers investigate its potential for anti-wrinkle and skin health benefits.

In the literature, Progeline appears most often in work focused on anti-aging, anti-wrinkle and skin health. 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.

Because it is catalogued here under powder peptides, Progeline also shows up in discussions of beauty. Coverage across those topics varies widely in quality and depth, and much of it is early-stage. Reading the underlying research directly is the only way to judge how strong any particular finding is.
