What are the benefits of peptide-based cosmetics in sun protection?

By /

  1. UV Protection:
    Sun protection products typically use powders and titanium dioxide to block or absorb UV rays, with effectiveness measured by their protection index. A higher index indicates better protection. However, powders can clog pores, and titanium dioxide may damage the skin after absorbing UV rays.

  2. Inhibition of Melanin Formation:
    UV rays can activate copper ions, which combine with tyrosine to form tyrosine copper, leading to melanin production. Peptides can inhibit free radicals and halt this reaction, helping to prevent melanin accumulation.

  3. Skin Repair:
    Peptides are excellent repair agents and possess anti-inflammatory, analgesic, and anti-swelling properties.
