Facial cleansers; how to use them well. In foam, gel or cream, facial cleansers provide a gentle sensation of freshness and purity. These facial treatments help to eliminate dead cells on the surface of the skin, allowing regeneration of the epidermis. We love them for their unique textures and for the well-being they offer, but be careful not to use them too often. The golden rule to respect is as follows; you use your facial cleanser no more than 3 times a week! Why ? Because beyond this frequency, the skin risks losing hydration and presenting areas of dryness.
