Olehenriksen-PHAT Glow FacialGet flawless skin in a flash with PHAs, the no downtime exfoliating acid and key ingredient in Oles first one step at home facial. What makes PHAs so special? Theyre fat, literally. Like AHAs, PHAs deliver skin perfecting, age fighting results, but PHAs are just a little plumper. Theyre a bigger molecule, so they dont go as deep as they loosen up the glue that binds the surface layer of skin together, and reveal the newer, fresher skin underneath.
