I may retry as it could be coincidental that the area i patch tested on for a week got deep painful acne like in the old days, and only on that side. I would give it two starts for being able to use it on my knees or something, but the product is too expensive for that... Maybe my skin was sensitive or just didn't react well, but I didn't like this. I actually liked the near skin simple therapy mist toner as my starter toner when i was scared and new to moisture toners.
