The basic ingredient in ProActiv is benzoyl peroxide (@ 2.5%) - one would be better served by buying mdEssentials 10.0% benzoyl peroxide cream from www.911skin.com
(costs $18). All the other stuff in ProActiv are moisturizers anyway (and I prefer to stick to Kiehls for those). Panzer
the Proactiv Revitalizing Toner and the Skin-Lightening Lotion aren't just moisturizers - they're good AHA-based exfoliants, and the latter also contains 2% hydroquinone and some kojic acid to help skin discolorations. 10% BP may work better for some people, but because of the trade-off of subtle but long-term cumulative damage to your skin, you should use the lowest percentage that works for you. Start with 2.5% and if that works, great - stick with it. If not, try 5%. If 5% doesn't work, try a 10% product. The only Proactiv products to avoid are the Advanced Blemish Treatment and the Daily Oil Control (because both contain drying alcohol and in the case of the latter, a form of aluminum starch found in deodorants) and the Refining Mask (which contains irritating sulfur). The other products in the Proactiv line are good, but not necessarily irreplaceable by comparable less-expensive products from other lines.
