I have never used it before I'm 40 and have had acne probs all my life. I especially have really bad blackheads on my nose and chin and some acne scarring that i want to treat. But, what strength should I start with and, should I use the gel or the cream or lotion? Also, everyone talks about high prices and prescriptions but, I see I can buy online for 28$ and I don't see it says anything about needing a prescription but, I admit I haven't yet tried to buy but, is there any reason I shouldn't buy these?
Thank you for any help you can give.
