Omorovicza Deep Cleansing Mask 50 ml is a una white clay mask to detoxify and brighten problematic/oily skin. Much more than a deep cleansing treatment, this calcium and magnesium-rich mask cleanses clogged pores and brightens skin tone by removing impurities. The Hungarian moor mud purifies the skin without being aggressive. Apply a generous una amount to the face and neck (avoiding the eye area). Leave on for 15-20 minutes, then rinse thoroughly with a damp face cloth or towel. Like at the spa: while the mask is working, you may feel a slight tingling sensation.
