Tetrapeptide-5

Tetrapeptide-5 is a short-chain peptide—a fragment made up of four amino acids linked together. Peptides are naturally occurring compounds found throughout the body, and in skincare they function as signalling molecules that communicate with skin cells.In formulations, tetrapeptide-5 is primarily used as a skin conditioning agent. Its role is to help improve the texture, smoothness and overall feel of the skin, often by supporting the skin's natural structural components.

Peptides like tetrapeptide-5 work by signalling to skin cells, particularly fibroblasts, which are responsible for producing collagen and elastin. When peptides interact with these cells, they can encourage the production of proteins that support skin structure and resilience.Additionally, tetrapeptide-5 functions as a humectant and conditioning agent, helping to attract and retain moisture in the skin's outer layers, which contributes to a smoother, more supple appearance.

Tetrapeptide-5 is typically found in serums, creams and moisturisers. It can be used daily as part of your routine. For best results, apply to clean skin before heavier products. It generally layers well with other ingredients, though as always, introduce new products gradually to monitor your skin's response.

Tetrapeptide-5 is generally well-tolerated and considered safe for most skin types. Peptides are unlikely to cause irritation, though those with known sensitivity to amino acids or peptide-based products should patch test first.
