Acetyl Tetrapeptide-11

Overview

Acetyl Tetrapeptide-11 (Ac-Pro-Pro-Tyr-Leu-NH2) is an active peptide that combats the visible signs of skin aging. It targets the epidermis, improving its cohesion, strength, and overall appearance, resulting in smoother, firmer skin.

Mechanism of Action

The skin aging process is significantly influenced by the reduction of Syndecan-1 (a proteoglycan vital for epidermal cohesion) and Collagen XVII (a protein crucial for dermo-epidermal junction adhesion). Acetyl Tetrapeptide-11 works by stimulating the synthesis of both these molecules. This action reinforces epidermal cohesion and improves adhesion between the dermis and epidermis.

Benefits

• Improved skin elasticity and firmness.
• Enhanced epidermal cohesion.
• Strengthened dermo-epidermal junction adhesion.
• Refined skin texture.

Applications

Acetyl Tetrapeptide-11 is ideal for use in anti-aging face creams and skincare products formulated for mature skin. Its efficacy has been demonstrated in studies on individuals over 65.
