Atrophic scars are a common and permanent complication of acne vulgaris, with a significant impact on quality of life. Their treatment is challenging due to the variety of scar types and the limitations of available therapies. There are several treatment options, including chemical peels, dermabrasion, and lasers. In this video, Dr. Bingrong Zhou, Department of Dermatology, Nanjing Medical University, will discuss multimode ultrapulsed fractional CO2 laser procedures, a new treatment modality for facial atrophic acne scars.

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.
