Query: didn't work

I was happy to see an oil control product that was more clean, not loaded with chemicals, or parabens, but it didn't work for me.It wasn't shine free from the start, & after an hour or two, I was blotting oil like usual.I was happy to see the positive reviews, and willing to give it a try.It would've been nice to have to have in my teen years, the salicylic acid probably would've helped with breakouts.Maybe I didn't give it enough time to work. I only used it for a few days.I'm going to give it another try before giving up on it.If you do decide to try it, use a light applicaton. Too much just flakes.
