LED Masks are skincare devices that use light-emitting diodes to improve skin health. They come in various colors, each targeting different skin concerns. For example, red light is often used to reduce wrinkles and promote collagen production, while blue light helps combat acne by killing bacteria. These masks are typically worn for a set period, allowing the light to penetrate the skin. Many users find them convenient for at-home treatments, as they can be used alongside other skincare routines. However, it's essential to follow the manufacturer's instructions for safe and effective use.
