Multimodal Laser Treatment of Photodamaged Skin
NCT07789002
Summary
The Multimodal Laser Project is a prospective, randomized, split-face clinical study investigating a novel combination of laser and light-based treatments for facial photodamage with the long-term perspective of improving skin cancer prevention. The study includes 35 patients with facial photodamage and AKs. One side of the face receives a multimodal treatment combining three complementary technologies: 1927-nm thulium laser, 1550-nm non-ablative fractional laser, and intense pulsed light (IPL), while the contralateral side serves as an untreated control. Participants are followed for 14 months to assess both clinical efficacy and longer-term preventive effects. The overall aim is not only to determine whether multimodal laser treatment improves photodamaged skin, but also to gain a deeper understanding of how the treatment affects the underlying biology of chronically sun-damaged skin and its potential role in skin cancer prevention.
