elfkin477, I used the concetrated stuff (that come sin those little plastic lemons). I would put some directly on the blemish at night. Sometimes during the day, too. I found it to reduce the size and duration of blemishes significantly more than benzoyl peroxide, salicylic acid, toothpaste, or anything else I tried, and without over-drying the surrounding area. I tried using it as a toner, too, to prevent new breakouts from forming, but no luck there.
