Feasibility and Safety of Using Combined Light-Emitting Diodes Versus Intense Pulsed Light Technology for the Improvement of Facial Hypervascularization in Adult Patients.

Superficial facial vascular lesions can be an aesthetic problem and a symptom of different skin diseases. It was to compare the efficacy and safety profiles of Dermalux Tri-Wave MD, based on three combined light-emitting diodes (LEDs) technology and intense pulsed light (IPL) for reducing the excess of facial vascularization due to superficial cutaneous vascular lesions. The study had a single-center, proof-of-concept, open-label, and prospective design. Two groups of adult patients were treated for facial hypervascularization, LED-Group with an LED device combining 633 and 830 nm and IPL-Group with an IPL (555-950 and 530-750 nm). Variables assessed were hemoglobin hyperconcentration (HH), hemoglobin-affected area (HAA) through Antera 3D, and pain using the Numeric Pain Rating Scale. Twenty subjects were included, 10 by group (50% female). LED-Group: Mean age 32.1 years (range, 2146). IPL-Group: Mean age 34.5 years (range, 2549). HH: LED-Group 100% had a moderate improvement; in the IPL-Group, 10% was moderate, and 90% was marked. HAA: LED-Group 10% had a slight improvement, 70% moderate, and 20% marked; in the IPL-Group, 100%, the improvement was marked. Seventy percent of LED-Group patients reported no pain, 30% mild; in the IPL-Group, 100% of patients reported severe pain. Treatment with combined red and near-infrared LEDs effectively reduced the excess of facial vascularization with moderate outcomes compared with IPL, but without secondary effects and no pain. This treatment could represent an effective, safe, and well-tolerated approach for facial vascular lesions.
