From my experience, LED light therapy masks are safe to use at home when you follow the manufacturer's guidelines. They are designed for at-home use, and most people find them easy to handle. If you have sensitive skin, test it on a small area first. This will help avoid any irritation. LED masks can be effective for acne and blemishes, especially with consistent use. Red light helps with inflammation, while blue light targets acne-causing bacteria. For each session, keep it short-usually around 10-20 minutes is perfect. Overdoing it won't speed up results, and you could risk irritation. Cleaning your mask is simple. Wipe the surface with a soft cloth after each use, and follow any cleaning instructions from the brand. Keep it in a dry place to protect the LEDs from damage.
