Palmitoyl Tripeptide-1 is a synthetic cosmetic tripeptide conjugated with a palmitoyl group to enhance skin penetration, studied in collagen and anti-aging research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for cosmetic raw-material research. Palmitoyl Tripeptide-1 is investigated in topical-formulation research for its potential to support collagen synthesis and skin regeneration, and is commonly applied in cell-based and formulation studies. The lyophilized format provides good stability and reproducible reconstitution for consistent experimental dosing. Every batch is quality-controlled and batch-specific COA can be supplied on request. Unopened product should be kept sealed at 2-8 degree C away from light and moisture, with -20 degree C recommended for long-term storage. We accept both trial and bulk orders, and OEM and private-label service is available. This peptide is for laboratory research use only.
