Polylactic Acid

Polylactic Acid is a biodegradable polymer derived from renewable resources like corn starch or sugarcane. In cosmetics, it primarily functions as a film-former, helping to create a thin, flexible layer on the skin or hair. It can also be used as a bulking agent or to provide a smooth texture to formulations.
