Palmitoyl Tripeptide-1
Palmitoyl Tripeptide-1 is a popular anti-ageing peptide used in UK skincare formulas. Often called a collagen-boosting signal peptide, it is frequently paired with other peptides in serums, eye creams and moisturisers to help skin look firmer and smoother. It is gentle enough for daily use and well tolerated by most skin types.
How it works in skincare
In cosmetics Palmitoyl Tripeptide-1 consists of three amino acids (glycine, histidine and lysine) linked to a palmitic acid chain that helps it penetrate the upper layers of the skin. Once there it sends signals to skin cells to support natural collagen production, improving the appearance of fine lines and firmness over time. It is commonly used in anti-ageing moisturisers, eye creams and targeted serums where it works well alongside ingredients such as hyaluronic acid and niacinamide.
