These are products that have been scientifically proven to help acne and can give you the confidence to make informed decisions. You don't have to be an expert to use these products. There are hundreds of free and paid websites that you can visit and find more than 100 free acne products to try. I am only going to review the ones that are in my opinion best, but the ones that have scientific proof for their effectiveness are still listed.
Some of these acne products are free and will be available through the following companies: Treat Your Acne by Tarte : This is a good acne product. It contains salicylic acid, retinoids, and is one of the only acne products that I would recommend buying. It is a great cleanser and also makes a great facial scrub. It is $8 on Amazon for a tub or $12 for a can. I am not sure about the exact numbers as they don't include shipping or shipping to other countries. The ingredients are also a little confusing. It has salicylic acid, a glycolic acid, and retinoids and may contain zinc oxide. The label does not list anything about the presence of zinc oxide. It seems as though some people have complained that zinc oxide causes redness. I have not experienced that.
