Ingredient Info

Polylysine is a natural antimicrobial compound derived from fermented sources that works by disrupting bacterial cell membranes. In skincare, it's primarily used for its ability to fight bacteria and help prevent infections, particularly in wound care or active-acne formulations.



Benefits

  • Antimicrobial activity against a broad range of bacteria
  • May help reduce bacterial biofilm formation
  • Potential support for wound healing and skin repair processes

Potential concerns

  • Limited safety data for topical skincare use in general consumers
  • May cause irritation or sensitivity in some individuals
  • Efficacy in finished skincare products depends heavily on formulation and concentration

Science: Recent research (2025) demonstrates polylysine's effectiveness as an antimicrobial agent in advanced wound-healing hydrogels, particularly against multidrug-resistant bacteria. However, most published data focuses on specialized medical applications rather than cosmetic skincare products for everyday consumer use.
