The big advantage of the MDacne treatment solution is that it provides you with everything you need for your acne treatment routine. There is no need to buy additional products such as exfoliating washes, moisturizers etc. Exfoliating washes and masks can actually, over dry your skin and make your acne worse. The only exception is sunscreen. If you need to be in the sun for more than 30 minutes, applying an oil-free sunscreen, is a good idea.
