Mechanism of action
Increased activity of superoxide dismutase (SOD)
Acetyl Tetrapeptide-5 supports SOD activity, which helps protect skin cells from oxidative stress. This peptide helps inhibit the glycation process, which leads to the formation of protein cross-links, which in turn improves skin elasticity and prevents premature aging.
Improvement of microcirculation
By stimulating microcirculation in the skin around the eyes, Acetyl Tetrapeptide-5 reduces vascular permeability and moisture loss. This action helps reduce puffiness and dark circles under the eyes, providing a more rested and youthful appearance.
Antiglycation effect
Glycation is the process by which sugars react with proteins to form advanced glycation end products (AGEs), which damage collagen and elastin, leading to loss of firmness and wrinkle formation. Acetyl Tetrapeptide-5 effectively inhibits this process, supporting skin structure and elasticity.
Cosmetic benefits
Thanks to its anti-puffiness properties , Acetyl Tetrapeptide-5 is particularly effective in reducing under-eye bags, which are often the result of poor lymphatic circulation and fluid buildup. This peptide improves lymphatic circulation, which reduces puffiness and promotes a more rested appearance. It also soothes and moisturizes the skin, improving its smoothness and elasticity. This peptide also has anti-inflammatory properties , helping to reduce irritation and redness. It is an excellent ingredient in products designed for sensitive and allergy-prone skin.
Scientific research
The effectiveness of Acetyl Tetrapeptide-5 has been confirmed in numerous in vivo studies. In one study, 20 volunteers used a cream containing Acetyl Tetrapeptide-5 for 60 days. The results showed that 70% of participants experienced a reduction in the appearance of under-eye bags by day 15 of use, and 95% of participants experienced a reduction by the end of the study.
Security
The product is considered a safe cosmetic ingredient. It does not exhibit irritating or toxic effects at the concentrations used. Its lack of classification as a hazardous substance under chemical regulations confirms its safety for both users and the environment.
