When I had a skin cancer removed from my face I decided I better get SERIOUS about skin care. Because I trust him explicitly, and he is known internationally for his research and work, I asked my plastic surgeon what he would recommend. He told me about the Kinerase products. They feel WONDERFUL on my face and I have peace of mind knowing my Doctor recommended them to me. I use the C8 Peptide serum and the day and night Ultimate moisturizers. My scar from the surgery is barely visible now and the signs of aging are reduced as well.
