I bought this after finding out from reading an article in Allure that Vitamin C and salicylic acid actually interact when used together, and can result in more irritation. Well, I'd been doing that exact thing and while it made sense I was horrified that this was the first I was reading about it. The article recommended Serum CF and I had heard other good things so I decided to try it. It's very light and easy to use, and while I can't say I've had noticeable results, I haven't experienced any adverse effects either. I think it's probably something subtle that just prevents further damage over time, anyway, which is exactly what I want.
