SyS Laboratory Mousse CO2 Mask with Shea Butter is a mask based on Shea butter that acts as a natural barrier that helps maintain skin hydration. The Shea Butter SyS Mousse CO2 Facial Mask has two components that when combined produce CO2, which is quickly absorbed by the skin. This reaction of the two components lasts between 20-30 min which provides greater texture and cleansing on the skin. It also contains ASD complex for its moisturizing properties that soothe, calm and nourish the most irritated skin. It is recommended to follow the following steps: 1) Clean the face and dry the face well. 2) Place your hands on the upper right corner where it says "Rub here" and rub 4 or 5 times to allow passage between F1 and F2. 3) To separate F1 and F2, tear along the vertical dotted line. Tear only how far the dotted line ends. 4) Make 3 or 4 folds on F1 from the bottom and press with your thumb. Verify that F1 is transferred correctly to F2. 5) Gently knead the mixture so that F1 and F2 mix completely. CO2 will be generated and the container will inflate slowly. 6) Open F2 as shown in the image. 7) Apply to the skin evenly avoiding the mouth and eyes. 8) Leave the mask on for 15-20 minutes. 9) Rinse with lukewarm water until any residue is removed.
