POLYLYSINE

Description

Polylysine is a versatile and innovative ingredient in skincare formulations, offering multiple benefits for various skin concerns. This naturally occurring homopolymer of L-lysine amino acids is synthesized by bacterial fermentation, primarily from Streptomyces albulus. Its unique structure consists of a long chain of lysine residues connected by peptide bonds between α-amino and ε-amino groups.

In skincare applications, polylysine functions as a potent antimicrobial agent, effectively combating a broad spectrum of bacteria, fungi, and yeasts. This property makes it particularly useful in acne-prone skin formulations and as a natural preservative alternative. Polylysine also demonstrates excellent moisturizing capabilities, helping to improve skin hydration and barrier function.

Furthermore, polylysine exhibits film-forming properties, creating a protective layer on the skin surface. This characteristic enhances the delivery of other active ingredients and provides a smooth, even texture to skincare products. Its low molecular weight allows for easy penetration into the skin, maximizing its efficacy.

Polylysine is generally well-tolerated, making it suitable for various skin types, including sensitive skin. Its biodegradability and non-toxic nature align with the growing demand for eco-friendly skincare ingredients.
