Pentapeptide-46

Pentapeptide-46 is a synthetic peptide—a short chain of amino acids—formulated to work with the skin's own defence systems. Peptides in skincare are valued because they can communicate with skin cells, potentially encouraging specific beneficial responses at a cellular level.This ingredient functions as a skin protectant, meaning it is intended to help reinforce the skin's ability to defend itself against environmental stressors and maintain its structural integrity.

Pentapeptide-46 works by signalling to skin cells, encouraging them to optimise their natural protective responses. As a peptide, it mimics communication patterns that occur naturally in the skin, potentially prompting cells to reinforce barrier function and defensive mechanisms.The ingredient is positioned to work with rather than replace the skin's intrinsic defence system—helping to maintain and support processes that are already occurring at a cellular level.

Pentapeptide-46 is typically used in serums or moisturisers as part of a daily routine. As with any peptide product, consistency matters—regular use is more likely to produce noticeable results than occasional application. It works well alongside other skincare actives, though introduce one new product at a time if your skin is sensitive.

Pentapeptide-46 is generally well-tolerated by most skin types. As with all skincare ingredients, patch test if you have known sensitivities to peptides or have very reactive skin.
