A Dual-Action Exfoliating Mask To Reoxygenate And Reveal New Skin. 1. Spread a thick layer of SCRUB & MASK over dry skin, avoiding the eye area. 2. Gently massage the product into the skin using circular movements. Continue for one minute. 3. Leave to rest. Bubbles start to form; this means that the mousse is retaining oxygen. 4. Once the bubbles have disappeared (after about ten minutes), rinse off with water. SCRUB & MASK can be used on all skin types, between one and three times a week. Step 1: new-skin revealing scrub Massage gently into clean skin: perlite spheres gently remove dead cells while an enzyme mimicking the embryo hatching process boosts exfoliation for a complete new-skin effect. Step 2: anti-ageing reoxygenating mask. When the scrub is completed, leave to settle; the texture will transform into an active mousse: NCTF boosts cell regeneration and micro-bubbles of oxygen are released to allow suffocated skin to breathe. When the bubbles have disappeared, it's time to rinse off.
