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.
