APIVITA Express Beauty Face Mask Green Clay is a mattifying face mask for oily and combination skin types. Formulated with green clay, a very absorbent type of clay which is known for its purifying action, this mask offers a deep-cleansing action to the pores. As a result, it reduces the appearance of blackheads. At the same time, it absorbs excess sebum from the surface of the skin, thus creating a matte, velvety-soft complexion.
