Unlike ordinary LED masks and patches, this product is very flexible and can be flexibly applied like a band-aid even to body parts with bends such as the face and joints, and is differentiated from existing products by its high light transmission efficiency to the subcutaneous layer even with low power. In addition, we optimized the performance through thorough light effect tests and bacterial tests according to LED Light Therapy standards, and applied certified special bands (beauty/wound/pain/skin diseases, etc.) in combination so that actual customers can experience skin improvement effects. (Waterproof level 3, wireless/wired free use, special band exchange use, LED patch is semi-permanent use)
