This clinical trial evaluated the safety and effectiveness of the NIRA Laser M2.1, with or without a topical treatment, for the treatment of full-face wrinkles in adults. Participants were assigned to one of two treatment arms: laser-only treatment or laser treatment followed by topical treatment. Wrinkle improvement was assessed using standardized facial photographs reviewed by blinded evaluators, and participant satisfaction and safety observations were also assessed.

This was a non-randomized, open-label, two-arm clinical study evaluating the NIRA Laser M2.1, with or without topical treatment, for treatment of full-face wrinkles in adults.

Participants were assigned to one of two study arms. Participants in Arm 1 received laser-only treatment. Participants in Arm 2 received laser treatment followed by topical treatment.

The study evaluated within-participant change from baseline in facial wrinkles using standardized before-and-after facial photographs reviewed by three blinded evaluators. Safety observations, including adverse events, participant satisfaction, and other facial observations were also assessed.
