Regular use of the skin-refining facial liquid supports the skin's regeneration process and visibly reduces impurities, enlarged pores, and subtle pigment changes in the complexion. Suitable for vegans To use: Apply to a cotton pad every other day after cleansing and spread on face, neck, and decollete until the skin feels well-moistened. Do not rinse. If it is well tolerated, the toner can also be used daily.
