If our kit products do not have you substantially clear after 2-4 months or if you absolutely can not use the organic compound benzoyl peroxide, my next recommendation is this mandelic acid serum from Vivant Skin Care. Use every other night for two weeks and then every night. Do not spot treat, instead rub lightly into the the entire break out area. Best if used in tandem with the Vivant BP 10% Gel Medication. Use a gentle cleanser with this product, such as any of our organic Hylunia cleansers. An alpha hydroxy acid, this product targets acne, aging and dark spots.
