Abstract
Background: Infrared light therapy, as a nonablative phototherapy, is known to improve wrinkles and skin laxity. Objectives: To investigate the efficacy and tolerability of broad-band infrared light therapy in patients with wrinkles and skin laxity of the face. Methods: We performed an open study in 29 patients who received broad-band infrared light therapy with onemonth interval up to 5 times. Results: Twenty-one percent of patients had marked improvement, 30% had moderate improvement, and 28% had slight improvement in wrinkles at the corners of the eyes, while 21% unchanged. Wrinkle grades in the tested area significantly reduced more than pre-treatment (p<0.005). Thirty-one percent of patients had marked improvement, 31% had moderate improvement, and 28% had slight improvement in laxity of the cheek skin, while 10% unchanged. No patients discontinued due to adverse effects and no patients showed hyperpigmentation or scarring after the treatments. Patient's satisfaction revealed satisfied to very satisfied rates in 76% of subjects. Conclusion: Phototherapy using this broad-band infrared light source was effective and well tolerated in the patients, suggesting that this phototherapy may be a new modality for the treatment of wrinkles and tightening of the face.
Highlights
The improvement of laxity of the face and neck without surgical procedures has been a great concern. Various treatment modalities such as laser and light-based treatments are known to be effective for wrinkles and skin laxity
In this study we report clinical effectiveness and tolerability of a novel light source emitting infrared broad-band light (800-1400 nm) on wrinkles and skin laxity of the face
Twenty-nine Japanese female patients with wrinkles and skin laxity of the face participated in this study that was conducted from May to June 2013
Summary
The improvement of laxity of the face and neck without surgical procedures has been a great concern Various treatment modalities such as laser and light-based treatments are known to be effective for wrinkles and skin laxity. A broad-band infrared (1100 to 1800 nm) light device was introduced in 2006 and some studies using this device and topical anesthesia showed improvements of skin laxity of the face and neck [6]. This therapy has been a non-ablative method after modification of exposure method [6]. As a nonablative phototherapy, is known to improve wrinkles and skin laxity
