Caffeoyl Hexapeptide-65

Caffeoyl hexapeptide-65 is a synthetic peptide—a short chain of amino acids—combined with caffeic acid, a polyphenol commonly found in plant sources. This combination creates a molecule designed to offer multiple skincare functions, primarily working as an antioxidant and skin protectant.The ingredient functions as a skin conditioner and antimicrobial agent, meaning it helps maintain skin texture whilst offering protective benefits against environmental stressors and unwanted microorganisms.

The caffeic acid component is known for its ability to scavenge free radicals—unstable molecules that damage skin cells and contribute to visible ageing. By binding these free radicals, the ingredient reduces oxidative stress in the skin.The peptide portion enhances skin conditioning, helping to maintain moisture and support the skin's structural integrity, whilst the antimicrobial properties work to maintain a balanced skin microbiome.

This ingredient is typically found in serums, moisturisers, and treatment products. It works well in combination with other antioxidants and can be used daily as part of a routine. For best results, layer it with other complementary ingredients such as vitamin C or niacinamide, though patch testing is sensible if you have reactive skin.

Peptides including caffeoyl hexapeptide-65 are generally well-tolerated in cosmetic formulations. No significant safety concerns are documented, though those with peptide sensitivities should patch test first.
