I *love* this product now that I know how to use it! I got this product a long time ago (years) and was using it on unopened pimples -- turns out that its a drying treatment to be used once the pimple is open! Once I started using it in the correct way, it has DRAMATICALLY helped the healing process and shortened my pimple timeline. So thankful that I got the complete acne kit and actually read the instructions lol.
PS - I also have sensitive skin and it has never bothered my skin.
