Disseborrhea is an imbalance related to sebum production, provoked by numerous factors. Sebum is naturally more abundant on certain areas of the body (among which the T-zone and the cheeks). Following the Bioderma philosophy, it puts biology at the service of dermatology: its Fluidactiv® complex lastingly purifies the epidermis by normalizing sebum quality, which limits pore obstruction and helps prevent irregularities. Our shine-control treatment’s special powder acts instantly, softening and mattifying for eight hours until it reaches a 90-percent effect after seven days. Shine decreases of 31% in 28 days. The soothing Mat & Smooth technology works directly on skin biology. Zinc purifies your skin while vitamin B6 regulates shine. Agaric and salicylic acids refine skin texture while tightening pores. Glycerin moisturizes your skin for 12 hours, making it smoother and healthier.
