After cleansing, apply Eu-Seb concentrate, massage lightly. Open a sachet, take out the mask, accurately apply to the whole face. Use side cuts for ears, then pull the lower part of the mask so that it covers the lower jaw and facial oval. Leave for 20 minutes. Take off the mask. Massage the leftover gel until it is fuly absorbed. Use once or twice a week. Can be used in between a professional course of treatments to boost the effect.
