Hi, I may be able to help.
I've written 2 major research papers on teenage acne in the past year and have treated so many patients with acne, be it teenage (hormonal), diet, allergy or excessive sebum.

Everyone has valid points in treating acne, but each person is different. I would strongly recommend that you visit someone who can assess the skin. Closed comedones (whiteheads) and open comedones (blackheads) are treated differently. Cystic acne is treated differently to 10-15 pimples on the face.

I could go on forever - but see someone who has experience with treating acne - ask how successful they've been in treating acne. You don't need a hundred products to clear it, nor do you need to spend much either. Feel free to ask me q's if you need.
