Using this Foreverlily 7-Color LED Facial Mask is easy. First, make sure your face is clean and dry. Then, put on the mask and choose the color light according to your skin needs. You can use it for about 15 - 20 minutes each time, a few times a week. When using, keep your eyes closed to avoid discomfort from the light. After use, gently wipe the mask with a soft, dry cloth. Store it in a cool, dry place away from direct sunlight. Don't use it if your skin is damaged or has open wounds. If you have any skin sensitivities, it's best to do a patch test first.
