The DNA Repair Serum is used as a regenerative care product or as a multi-talent against photoaging. Light protection filters only protect against UV radiation. These make up less than ten percent of solar radiation. The rest consists of visible light and infrared light. No light protection filters protect against this, but they also cause DNA and cell damage as well as photoaging. In cell tests, the DNA Repair Serum protects up to 99% against free radicals from radiation and is an ideal supplement to classic sun protection. It actively absorbs blue light. Photolyase, a natural enzyme from algae, helps to repair DNA damage to the skin.  This premium product from Dr. Hauck contains the world's first certified astaxanthin for natural cosmetics. It is extracted from algae and is 750 times stronger than co-enzyme Q10 and 6000 times stronger than vitamin C.
