Co-administration notes from the literature

Verbatim summary text pulled from each compound's profile data. Researchers studying Matrixyl and Palmitoyl Dipeptide-6 have published these mechanism-level observations. Not a co-administration recommendation.

Evidence level: mechanistic only

The gold-standard signal-peptide cosmetic active with the most published clinical substantiation in the palmitoyl-lipopeptide class. Commonly combined with Palmitoyl Dipeptide-6 in firming serums to layer two matrikine-type peptides at different inclusion levels. Pal-KTTKS at 3–8 ppm plus pal-VW at 1–4% is a common formulation pattern.
