Dermatological skin care Uriage Eau Thermale HA Booster Serum combines the hydrating power of Uriage thermal water with 1.5% pure and natural hyaluronic acid, acting on signs of skin dehydration (fine wrinkles, discomfort, dull skin, etc.). Medium/low molecular hyaluronic acid, due to its "sponge" effect (i.e. by retaining a large amount of water), plumps the skin. Hyaluronic acid with a very low molecular weight gives the skin tone and elasticity. Other active ingredients Aquaxyl + extract from the flowers of the medicinal plant support the hydration of the individual layers of the skin and protect against aggressive environmental influences. The serum improves the texture of the skin (fine wrinkles caused by dehydration are smoothed out) and gives it a truly velvety and brightened appearance.
