Biologique Recherche Sérum Dermopore is a rebalancing serum. Containing java tea, Serum Dermopore reduces sebum secretion, tightens pores, refines skin irregularities and purifies the epidermis. Pores play a vital role in the physiology of the skin, allowing it to “breathe”, so it is essential to prevent and treat dilated pores before inflammation sets in and acne appears. Serum Dermopore leaves skin perfectly matte, balanced and even. Best for seborrheic skin types, which are prone to acne and skin imperfections.
