BRT-FS145B Purchased in 2024, I've been using other facial devices, so I've only used this one once or twice. All accessories, manuals, etc., are included as they were at the time of purchase. Alcohol-sterilized. Operation confirmed. Salon-quality results anytime at home. ■ 16 dual-row LEDs simultaneously emit red and blue light. Red LEDs promote collagen production, which is the source of firmness. By directly warming the entire skin, it gives a firm impression. Blue LEDs have a tightening effect. They refine the overall skin texture and lead to smoother skin. ■ Dual Mode EMS Brighte's unique EMS By combining low and high frequencies, it achieves a comfortable sensation and stimulation. Directly approaches muscles and facial muscles with EMS stimulation. The tingling, pleasant stimulation emitted from 38 electrodes directly works on the muscles throughout the body, loosening and tightening the skin. ■ Intelligent RF Equipped with automatic adjustment RF. Warms the skin and cares for sagging. Automatically adjusts the appropriate RF temperature for each area. By evenly distributing the warmth, it cares for firmness and sagging without unevenness. Also, it reacts to moisture and warms from deep within, improving circulation with warmth. This function is also installed in many esthetic salons. ■ 10 functions in 1 device, supporting various uses ・ Transparency care ・ Lift care ・ Firmness/Tightening ・ Anti-aging care ・ Facial muscle training ・ Scalp care ・ Warmth care ・ Neck care ・ Body care ・ Fine wrinkle care due to dryness
