Acetyl Dipeptide-13 Diphenylglycine

Product Overview

Acetyl Dipeptide-13 Diphenylglycine, with CAS No.: 324755-72-8, is a synthetic tetrapeptide presented as a white powder with a purity of ≥95%. Specifically developed for premium anti-aging skincare applications, this peptide targets the key concerns of mature skin, including sagging, loss of firmness and reduced elasticity. By combining two core mechanisms of action—inhibiting elastase activity to protect elastin from degradation and stimulating collagen I synthesis to enhance skin resilience—it delivers reliable, visible improvements in skin tone and texture. Its high purity and inherent stability make it a consistent, high-performance ingredient for advanced skincare formulations, meeting the stringent demands of high-end cosmetic brands focused on effective anti-aging solutions.

Core Mechanism of Action

The anti-aging efficacy of Acetyl Dipeptide-13 Diphenylglycine stems from its dual-targeted biological activity. First, it acts as an elastase inhibitor: elastase is an enzyme that breaks down elastin, the protein responsible for maintaining skin’s elasticity and suppleness. As skin ages, elastase activity increases, leading to the gradual degradation of elastin fibers, which results in sagging and loss of bounce. By inhibiting this enzyme, the peptide protects existing elastin from premature breakdown, preserving the skin’s natural elastic structure. Second, it stimulates the synthesis of Type I collagen, the most abundant collagen type in the skin, which provides structural support and firmness. With age, collagen production declines significantly, leading to thinner, less resilient skin. The peptide’s ability to boost collagen I synthesis helps replenish this vital protein, enhancing skin thickness, firmness and overall resilience, reducing the appearance of sagging and promoting a more youthful contour.

Application Scenarios

Acetyl Dipeptide-13 Diphenylglycine is widely used in a variety of premium anti-aging skincare products, including concentrated anti-aging serums, rich moisturizing creams, firming body lotions, targeted neck and décolletage treatments, and anti-aging eye creams. Its ability to improve skin firmness and elasticity makes it ideal for products designed to address sagging and loss of tone in mature skin. It can be integrated into both standalone anti-aging formulations and multi-benefit skincare products that combine anti-aging, hydration and brightening properties, offering flexibility for cosmetic brands to create tailored solutions for different consumer needs.

Industry Pain Points Addressed

1. Inconsistent Anti-Aging Efficacy: Many over-the-counter anti-aging ingredients only target one aspect of skin aging, leading to limited visible results. This peptide’s dual-action mechanism addresses both elastin degradation and collagen loss, delivering more comprehensive and noticeable improvements in skin firmness.
2. Formulation Instability: Some peptide ingredients degrade quickly in skincare formulations, reducing their efficacy over time. Acetyl Dipeptide-13 Diphenylglycine’s inherent stability ensures it maintains its performance throughout the product’s shelf life, providing reliable results for consumers.
3. Low Purity Concerns: Impure raw materials can cause skin irritation or inconsistent performance. With a purity of ≥95%, this peptide minimizes these risks, making it suitable for sensitive skin and ensuring consistent formulation results.
4. Lack of Targeted Solutions for Mature Skin: Many anti-aging products are designed for general use, failing to address the specific needs of mature skin, such as severe sagging and loss of elasticity. This peptide is specifically formulated to target these concerns, filling a gap in the high-end skincare market for specialized mature skin solutions.
