I'm surprised that Mandelic Acid is not in many acne products. After using this for several months my skin is better than ever. Typically I'm prone to acne, but this cleared it up better than any other product I have tired. My skin tone looks really great as well.
I cannot believe there have not been more reviews on this product. I have very sensitive skin along with redness. After trying glycolic and retinol products as well as lactic acid products with no success and tons of irritation, I almost gave up. I tried this one last product and it works. I am fair and had sun damage along with hyper pigmentation on my upper lip after a summer in the sun. I used this item for 2 weeks and followed the directions and I am thrilled to say that I look good with little foundation coverage. Many of my issues have diminished. Might I recommend a nice moisturizer with this product. I use one for sensitive skin and aloe based. I layer it with this product 1 hr before bed to let it sink in. Enjoy.
