Uses low-level heat to kill acne bacteria. It promises to improve most pimples in 24-48 hours. Guess what, it does work!! It’s small and handy. It comes in different colors and is easy to use. I would definitely recommend this for acne control. It’s great to have around when you’re PMS-ing, you can take care of breakouts fast. If you have severe acne, this will not be a miracle product, but it will help control blemishes.
