| Polylysine |
Polylysine is a naturally occurring polymer composed of the amino acid lysine, typically produced by the fermentation of bacteria, such as Streptomyces albulus. Polylysine is known for its antioxidant, antimicrobial and film-forming properties. It was used as a food preservative due to its antimicrobial properties, and its safety and effectiveness has made it a great ingredient in skincare. It has the ability to protect the skin, prevent bacterial growth and maintain moisture making it an effective ingredient for combating acne. By reducing bacterial colonisation on the skin, polylysine helps prevent breakouts and supports healthier, clearer skin. To be more specific, P.acnes is a type of bacteria that naturally lives on your skin. While some strains are harmless or even good for your skin, others can cause inflammation and lead to acne. These harmful strains thrive in oily, clogged pores, triggering a response from your immune system that results in redness, swelling, and pimples. Polylysine works by specifically targeting and weakening these acne-causing bacteria, breaking down their cell walls and preventing them from growing. Additionally, due to the fact that polylysine creates a protective layer on the skin's surface and acts as a film-forming ingredient, it assists in locking in moisture and preventing transepidermal water loss (TEWL) leaving the skin hydrated as well as protected.
