ABIB Mild Acidic pH Sheet Mask Glutathiosome Fit 10 Sheets is a Korean brightening sheet mask set that targets dark spots, pigmentation, and dull skin. Each sheet is made from Abib's ALBAM cloth (bamboo fiber and albumin) coated with Glutathiosome, Abib's proprietary liposome-encapsulated Glutathione complex. The mildly acidic pH matches the skin's natural acid mantle. Niacinamide and triple Vitamin C work alongside Glutathiosome for visible brightening in 3 days. Fragrance-free, dermatologically tested.
