I studied in Korea, and the TV shopping programs here in Korea were too hot, so I bought them out of curiosity. Near infrared rays directly irradiate the stomach and feel very comfortable. LUMIDIET is a kind of home care equipment, which helps to reduce fat by using near-infrared LED. Another principle is to reduce the size of fat cells by heating infrared rays. When the near infrared rays reach the fat cells, holes are temporarily formed on the cells, and the decomposed fat is discharged from the cells. The effect of near infrared ray is amazing, such as relieving pain, improving skin, reducing fat, caring hair and treating rhinitis. So don't worry about any side effects, you can use it with confidence.
