KEY INGREDIENTS
Hyaluronic Acid (HA): A polysaccharide (carbohydrate polymer) found naturally within the skin. When used in a formula, HA is an effective humectant that can hold a large amount of water to help maintain the skin's moisture. Madecassoside: Derived from the Centella Asiatica plant, madecassoside is known for its nourishing properties. Glycerin: Derived from vegetable sources, it's an excellent humectant. It helps hydrate skin by absorbing water from the surrounding environment. Vitamin B5: Panthenol (provitamin B5) is a key ingredient used in some La Roche-Posay formulas to help the skin feel soothed and moisturized. Dimethicone: A silicone-based polymer used as a skin protectant to help reduce water loss. La Roche-Posay Prebiotic Thermal Water: A soothing water sourced in the town of La Roche-Posay in France and a core ingredient in most of our products. It contains a unique combination of minerals, trace elements, and a high concentration of selenium, a natural antioxidant.
