after 70 years of NOT caring for my skin, squamous cell carcinoma, surfaced, leaving seventeen stitches down the middle of my face. In my search to ward off as many future carcinomas as I can, I discovered Photozyme DNA Repair. Their representative, Greg, has helped me regain my dignity more than any doctor. My mom, HAS cared for her skin for 87 years.......she too, now uses Photozymes DNA repair and the ONE brown spot she HAD, has mostly resolved due to the efficacy of Photozyme DNA repair. Wish 'doctors' would guide you to this product as they are cutting out the cancer,
