Skinceuticals is one of my favorite brands. It was developed by doctors, and it has good solid scientific articles (with histology and biopsies and everything) to show it works. As with many lines, I cherry pick the products I think work the best. This is a product I personally use.
Phloretin CF® represents a new class of preventive and corrective topical antioxidant treatment. SkinCeuticals developed this patent-pending breakthrough technology combining the newly-discovered, broad-range power of phloretin with their already well known and scientifically proven effects of vitamin C and ferulic acid. This new product corrects damage at every level.
Phloretin CF®, a broad-spectrum treatment
1. It protects against free radicals and other reactive molecules known to cause damage and DNA mutations.
2. It corrects existing damage by stimulating the synthesis of essential proteins and fibers and accelerating cell turnover.
The result is a better structure on the inside of the skin, and more youthful radiant visible skin.
