Signal peptides work by stimulating skin fibroblasts to produce more collagen and other extracellular matrix components. This enhances skin firmness and reduces signs of aging.
Signal peptides vs. other peptides in cosmetics
Unlike other peptides, signal peptides directly influence skin cell behavior, making them particularly effective for anti-aging and skin regeneration.
Examples of signal peptides in topical treatments
Peptides such as palmitoyl pentapeptide-3 and palmitoyl tripeptide-5 have shown to improve skin texture and elasticity. These peptides are often key ingredients in high-end anti-aging skincare products.
