Palmitoyl Tripeptide-5
Palmitoyl Tripeptide-5 is a lab-made peptide used in anti-ageing skincare to help skin look firmer and smoother. Often called a collagen-boosting signal peptide, it is popular in serums, creams and eye treatments aimed at mature skin. It is gentle enough for daily use and pairs well with moisturisers and other peptides.
How it works in skincare
In cosmetics Palmitoyl Tripeptide-5 works by mimicking the body’s natural communication signals that encourage fibroblasts to produce more collagen and elastin. The added palmitoyl chain helps the peptide penetrate the upper layers of the skin more effectively, where it supports the skin’s extracellular matrix. This helps improve the appearance of firmness and reduces the look of fine lines without irritation, making it a staple in modern anti-ageing formulations.

Where it comes from
Palmitoyl Tripeptide-5 is a synthetic peptide created by combining three amino acids (lysine, valine and threonine) with a palmitic acid chain. While the individual amino acids can be plant-derived, the final ingredient is produced in a laboratory under controlled cosmetic-grade conditions.
