4 boxes of SkinMedica ultra hydrating sheet mask, 3 masks in each box, for a total of 12 masks. All 4 boxes are sealed, never used or opened. I will also be throwing an additional surprise SkinMedica gift with this purchase. These hydrating masks, leave skin feeling soft, smooth & moisturized. Hydrators, such as apple stems cell extract and cucumber extracts, nourish and moisturizer the skin while free tea extracts, ginseng and Maui provide antioxidants protection. Use weekly or as needed.
