Caffeoyl Tripeptide-1

Caffeoyl tripeptide-1 is a peptide derived from caffeic acid, a naturally occurring polyphenol found in plants. In skincare formulations, it functions as an antioxidant and skin-protective agent, working to neutralise free radicals and help shield the skin from environmental damage.This ingredient bridges peptide chemistry with antioxidant capability, making it useful in formulations designed to support skin resilience and address oxidative stress—a key driver of visible ageing and skin irritation.

Caffeoyl tripeptide-1 works primarily by donating electrons to neutralise free radicals before they can damage skin cells. Free radicals are unstable molecules created by UV light, pollution, and natural metabolic processes; left unchecked, they contribute to collagen breakdown, barrier compromise, and visible signs of ageing.By intercepting these reactive molecules, the ingredient helps protect skin's structural integrity and reduce the inflammatory cascade that follows oxidative stress. It may also work synergistically with the skin's own antioxidant systems.

Caffeoyl tripeptide-1 is most effective as part of a layered antioxidant routine. Use it in a serum or treatment product applied to clean skin in the morning or evening, or both. It works well alongside sunscreen (which prevents free-radical formation) and other stable antioxidants. No special application technique is required; allow the product to absorb fully before applying moisturiser or other treatments.

Caffeoyl tripeptide-1 is generally well-tolerated across skin types and has a low risk of irritation. Those with sensitivity to peptides or plant-derived ingredients should patch-test first, though allergic reactions are uncommon.
