DERMAFIRM Age Reviving Micro Crystal Patch Plus is a set of 3 packs x 3 patches that are designed to provide intense hydration and absorption to the skin. The patches are made with micro-sized crystal structures that contain hydrolyzed hyaluronic acid and other ingredients, ensuring minimal loss of functional substances during the manufacturing process. To use, cleanse and tone the skin, remove the protective film from the patch, place it on the desired area, press it firmly onto the skin, leave it on for at least 2 hours, and then remove it and finish with skincare. It is recommended to use the patches 2-3 times a week for optimal results.
