Thalgo Plasmalg Gel is a 100% Micronized Patented Marine Algae in gel suspension. It acts as a catalyst to break down the skin barrier for better absorption of nutrients. The epidermis is remineralized. The passage of the marine ions (in suspension in the bath or body wrap) through the skin is improved. During heat treatments, perspiration is activated and the elimination of waste increased. Sebum flow is regulated.
