This mask contains arbutin which is widely used as a whitening and anti-aging beauty product to enhance skin fairness and help fight dark spots, it also contains vitamin c which is an antioxident which helps the skin in many ways. These two main ingredients along with all the rest make this mask perfect for my acne-prone dry skin. It has no fragance, a big plus for me, since I have sensitive skin and cannot stand products full of fragance. It leaves my skin supple, smooth, and I can definitely can see this light, glowly effect right after I take the mask off. Love it even more for never breaking me out. I would easily repruchased, but gave it four stars only because the price is a little high for me for only four masks.
