A potent yet still gentle acid toner that actually delivers results without the side effects! This is the gentlest of the BR Lotions and a good starting point if you want to try chemical exfoliants, as it does not contain Glycolic Acid, which while effective, is also the most irritating of the AHAs. I only use this 2-3 times a week when I'm not using other actives, and it's made a big difference in my skin tone and texture. Expensive, but I got the small bottle and a little goes a long way!
