Ionax facial scrub

Ionax is this exfoliant facial scrub my dermatologist prescribes. It is highly abrasive and has a citrusy, almost acidic scent. I only use it once a week now, but smelling it brings me back to third year high school, when I had really bad acne on my forehead. Back then I would use Ionax everyday. In particular, it reminds me of my trip to Japan on an exchange program. I didn't realize how cold and dry the weather would be. I continued using the scrub for the first few days, even though my skin was extremely dry. After a few days, my forehead started peeling. It was sort of yucky until I realized my pores were closing and my acne was subsiding. I still don't know if it was the scrub or the weather - or a combination of both - that helped treat my pimples, but it felt great.
