Avène XeraCalm A.D Lipid-Replenishing Balm is an ultra-rich, lipid-replenishing balm directly targets itching, redness and irritation to nourish and restore skin prone to atopic dermatitis and eczema. Formulated with minimal ingredients essential to rehydrating and maintaining a healthy balance in skin’s microbiome. The micro-biome is the top layer of the skin filled with microorganisms like bacteria, yeast, and skin flora – their job is to defend against bad bacteria. The microbiome environment can easily be influenced by temperature, hormones, UV exposure, and even skin care. Patented I-Modulia helps to maintain a well balanced microbiome while supporting the skin's defense system for a normal, healthy skin. Exclusive, patented airless pump keeps the cream completely sterile and safe for its entire use without any preservatives, parabens, dyes or fragrance.
