Before applying the mask clean and tone the skin (Hidraderm Water Cleansing Milk and Hidraderm Oatmeal Roses water). Then apply evenly over the entire face using the fingertips or a brush, avoiding the eye contour area, making sure to apply enough of the mask (approximately 1 mm). Let the mask sit for 10-15 minutes. After this time, it is important to remove the product with cold water, if desired using a sponge. After, for best results, apply vitamin C Radiance luminous fluid.
