A clinical study found that this component is not even close to as successful as dermatological procedures in reducing signs of ageing, despite the claims made for acetyl hexapeptide-8 (argireline).

Other studies on the topical application of a moisturiser containing a 10% concentration of acetyl hexapeptide-8 have shown that it does not penetrate beyond the uppermost layers of skin, even after several hours. It has no involvement in the underlying layers that cause expression lines to develop.
