Synthetically derived peptide that is used in a wide range of skincare and makeup products.
Despite claims being made for acetyl hexapeptide-8 (argireline), there is a clinical study revealing that this ingredient is not even remotely as effective as dermatological procedures in reducing signs of aging.
