Acetyl Tetrapeptide-5 has the ability to increase superoxide dismutase (SOD) activity, which helps inhibit glycosylation and prevents protein cross-linking, resulting in improved skin elasticity. Acetyl Tetrapeptide-5 improves microcirculation in the skin around the eyes, reducing blood vessel permeability and moisture loss, resulting in the reduction of puffiness and dark circles under the eyes.
Used in cosmetic products, Acetyl Tetrapeptide-5 exhibits anti-aging, anti-inflammatory and firming effects. It is used in products such as gels, creams, eye serums and masks. Its effectiveness was confirmed in in vivo studies on a group of volunteers. Participants used a cream containing 0.01% Eyeseryl for 60 days, which resulted in a significant improvement in the appearance of bags under the eyes and a reduction in swelling.
