Tripeptide-76

Tripeptide-76 is a short-chain peptide—a fragment composed of three amino acids joined together. Peptides are naturally occurring building blocks found throughout the body, and those used in skincare are typically derived synthetically or extracted from natural sources.In cosmetic formulations, tripeptide-76 is included with the intention of supporting skin structure and function, though specific claims about its mechanism remain limited in publicly available research. Like other peptides, it may interact with skin cells to influence cellular communication and skin integrity.

Peptides work by mimicking or supporting natural processes within the skin. Tripeptide-76 is thought to interact with skin cells and may influence how cells communicate with one another—a process essential for maintaining skin structure and barrier function.As the skin ages, the production of key structural proteins like collagen naturally decreases. By introducing peptides into skincare, the aim is to support the skin's natural maintenance systems and potentially slow visible signs of ageing. However, the precise mechanism of action for tripeptide-76 specifically requires further research.

Tripeptide-76 is typically found in serums, creams, and moisturisers. Apply to clean skin as part of your regular routine, layering it with other actives according to your skin's tolerance. Peptides work best as part of a consistent routine; results, if any, tend to emerge over several weeks of regular use rather than immediately. Pair with sun protection to address the extrinsic factors that drive visible skin ageing.

Peptides are generally well-tolerated by most skin types and are unlikely to cause irritation. As with any new ingredient, patch test first if you have sensitive or reactive skin.
