I have used a few vitamin C serums in the past but none of them worked. I was left disappointed and regretting that I spent my hard-earned money on ineffective products. When I tried the Vitamin CC serum from American Cosmetic and More, I was skeptical at first but within a few days, I noted a dramatic change in my skin. After a few weeks of using the product, my face is smooth, looking rejuvenated and vibrant. I like the way it makes my face feel. I don’t think my face has ever felt or looked better. I love this product and would recommend it to anybody!
