Tripeptide-55

Tripeptide-55 is a short-chain peptide—a fragment of amino acids—formulated to provide antioxidant and skin-protective functions. Peptides are valued in skincare for their small molecular size, which allows better penetration into the skin, and their ability to signal specific benefits to skin cells.This ingredient works primarily as an antioxidant, helping to neutralise free radicals that accumulate from sun exposure, pollution, and oxidative stress. By doing so, it aims to reduce the cellular damage associated with premature ageing and support the skin's natural defence mechanisms.

As the skin ages, it experiences a gradual loss of structural proteins like collagen and a decline in its natural defence systems. Environmental factors—particularly sun exposure—accelerate this process through the generation of free radicals, unstable molecules that damage skin cells.Tripeptide-55 operates as an antioxidant, meaning it can donate electrons to free radicals and stabilise them, preventing them from causing further cellular damage. By reducing oxidative stress, the ingredient may help preserve skin integrity and support the skin's immune system in maintaining healthy tissue h…

Tripeptide-55 is typically found in serums, moisturisers, and targeted treatments. Apply it to clean skin, ideally in the morning or evening as part of your routine. It works well alongside other antioxidants and can be layered with other actives, though starting with one new ingredient at a time allows you to assess tolerance. Consistent use is more important than occasional application when addressing environmental damage.

Peptides are generally well-tolerated across skin types with low irritancy potential. No significant safety concerns are documented for Tripeptide-55 at typical cosmetic concentrations.
