Constant Motion Delivery of Broadband Light Energy for Skin Tightening in Korean Patients

Broadband light (BBL) induces photothermolysis of key chromophores in the skin to achieve overall clinical improvement in aged skin. In the present case series, we describe three Korean patients who were treated with BBL using a constant motion delivery technique for skin tightening. The patients were treated with one or two sessions of BBL along the mid-face, lower face, and upper part of the neck using an 800ST cut-off filter, an energy intensity of 5 W/cm 2 to 10 W/cm 2 , a pulse duration of 10 seconds, and a cooling crystal temperature of 25°C via a constant motion technique. The estimated total accumulation energy was approximately 15,000 J/session to 20,000 J/session. At one month after the final treatment, patients showed remarkable clinical improvement in overall skin texture and tone. Objective clinical assessment revealed marked improvement in zygomatic wrinkles, nasolabial folds, and perioral expression wrinkles at the cheek in the mid-face, as well as marionette lines and jaw lines in the lower face. Moreover, no major side effects were reported in our patients of Fitzpatrick skin phototype III or IV.
