Broadband light treatment using static operation and constant motion techniques for skin tightening in Asian patients

BACKGROUND: Broadband light (BBL) devices irradiate photons of different wavelength to induce photothermal reactions on various aging-related chromophores. OBJECTIVES: To evaluate three BBL treatment settings for skin tightening in Asian patients. METHODS: A total of 27 patients underwent three sessions of BBL treatment via (1) an 800-nm cutoff filter using a static operation technique and a 695-nm cutoff filter using a constant motion technique (group 1, N = 9), (2) an 800-nm cutoff filter using a constant motion technique (group 2, N = 9), and (3) a 590-nm cutoff filter using a constant motion technique (group 3, N = 9). RESULTS: The patients in group 1 presented marked clinical improvements in zygomatic wrinkles, nasolabial folds, and marionette lines, with a median overall global aesthetic improvement scale (GAIS) score of 3. Meanwhile, patients in group 2 exhibited noticeable improvements in zygomatic wrinkles, nasolabial folds, perioral expression wrinkles at the cheek, and marionette lines, with a median GAIS score of 3. Patients in group 3 experienced improvement in skin tone and texture, zygomatic wrinkles, nasolabial folds, and marionette lines, with a median GAIS score of 2. CONCLUSIONS: Our data demonstrated that BBL treatment for nonablative, noninvasive skin tightening elicits satisfactory clinical outcomes.
