Used after micellar water cleanser and TCA peel. Has TONS of serum and interior plastic lining to help you unfold; the mask fabric itself is quite sheer but somehow soaked in lots of product & deposits it smoothly over 15-25min. Very narrow eye holes but I like having the product directly beneath my eyes. Great fit, especially around nose lines. Soothed very agitated skin & helped restore lost moisture. Skin soft & glowing the next morning - Will buy again!
