Hexanoyl Dipeptide-3 Norleucine Acetate

Hexanoyl dipeptide-3 norleucine acetate is a synthetic tripeptide that helps skin’s surface (known as the stratum corneum) shed properly plus speed up surface renewal for fresher, more vibrant-looking skin and visibly smoothed wrinkles.

The manufacturer has named this peptide “PerfectionPeptide P3” for its ability to refine skin’s appearance by smoothing the surface so it’s better able to reflect light and also maintain hydration.

This peptide works by competing with proteins on skin’s surface that, when damaged, can impede exfoliation. It steps in to enhance skin’s ability to shed, and nicely complements the multi-level benefits alpha and beta hydroxy acids provide. In fact, this peptide is stable at a pH of 3.5, which means it can be used in the same formula as exfoliating acids.

Hexanoyl dipeptide-3 norleucine acetate has a recommended usage level of 0.5–3%. It’s definitely an intriguing peptide, although there are others that have more substantial research supporting their claims.
