Biossance Squalane + Vitamin C Rose Mask This Biossance Squalane + Vitamin C Rose Mask ($48) goes on clear as a gel, and then transforms into a white mask as the moisture on the skin activates it. It's packed with calming rose otto oil, soothing squalane, and 10 percent L-ascorbic acid (aka vitamin C).
