DNA damage induced by UV and DNA repair ability, how does it work?
Prof. Wei LIU, MD, Phd
Dr. Wei Liu, Dermatologist at the Chinese PLA Air Force General Hospital, discusses how UV radiation damages DNA - a topic directly connected to sunscreen development. He explains that while skin has natural DNA repair mechanisms, this capacity declines with age - particularly in elderly individuals and light skin phototypes (I-II) - increasing the risk of mutations and skin cancer. Based on these findings, Dr. Liu emphasizes to the European dermatological community the critical importance of incorporating DNA-repairing active ingredients in sunscreens as a preventive strategy against cumulative sun damage.
