Aqua Bounce Flash Mask is a hydrating second-skin effect mask from Biotherm that deeply infuses the skin with intense hydration, powered by the combination of hyaluronic acid and Life Plankton probiotic water, which helps to remove impurities with an exfoliating effect, absorbs the sebum and purifies the skin. A single application is enough to achieve deeply plump, super moist and supple skin. How to use: After cleansing your face, carefully unfold and place the Biotherm Aqua Bounce Mask on your skin. Gently remove the blue film and smooth the mask with your fingers to create optimal contact with your skin. Leave on for 15 minutes, then gently remove, then massage in any remaining product you may have, or remove additional product with a cotton ball. No need to rinse.
