Dipeptide-4 (Phe-Trp): DNA shield, anti-glycation, boosts SOD/catalase. The “Rescue & Protect” peptide for anti-aging.
Advantage and Benefit
| Feature | Details |
| DNA Shield | Acts as a molecular umbrella for the cell nucleus, reducing UV and pollution-induced DNA strand breaks to prevent cellular senescence. |
| Anti-Carbonylation | Targets carbonyl stress, a severe form of protein damage, preserving skin’s biomechanical resilience. |
| Anti-Glycation | Inhibits AGEs formation to prevent collagen fiber stiffening and yellowing, maintaining skin elasticity. |
| Antioxidant Amplification | Upregulates SOD and catalase activity, training the skin to fight free radicals and strengthening natural defenses against chronic stress. |
FAQs
Q1. Can Dipeptide-4 (Phe-Trp) prevent UV-induced DNA damage?
Answer: Yes, by neutralizing free radicals and oxidative stress. It reduces lipid peroxidation and enhances SOD activity, shielding cells from UV/environmental DNA damage. (Based on commercial supplier data)
Q2. How does Dipeptide-4 (Phe-Trp) fight skin glycation?
Answer: It directly inhibits the formation of Advanced Glycation End-products (AGEs), preventing collagen cross-linking and preserving skin elasticity. (Supported by supplier research)
Q3. Can Dipeptide-4 (Phe-Trp) boost the skin’s own antioxidant system?
Answer: Yes, it upregulates the activity of Superoxide Dismutase (SOD) and Catalase, strengthening the skin‘s natural defenses. (Data from manufacturer and patent sources)
Q4. English: What is the optimal pH range for Dipeptide-4 (Phe-Trp) stability?
Answer: It is stable at pH 5.5 to 7.0. While some sources claim a wider pH 4-8 range, the peptide maintains optimal stability in neutral to weakly acidic environments. (Best practice guideline)
