I have adult acne, and it's really bad right now.
I've been using my facial cleansers and benzoyl peroxide and salicylic acid topical treatments so that they won't go to waste, but I've also tried the oil cleansing method. I used to use it in conjunction with the cleansers, and every other thing I had in my bathroom (the benzoyl and salicylic acid, cleansers, moisturizers, etc). But I was told I was putting too much on my face and was overwhelming my face, making the acne worse.
I'm thinking of transitioning to the oil cleansing method once I use the cleansers, and using the topical treatment gels, too (since my acne is stubborn).
