Can you tell me if you would need to cover your eyes when using a skin laser?

No. When in use, the Wellay @home Skin Laser is placed on your skin so no, you don't have to cover your eyes. For eye safety, the Smart "Face-Away" sensor ensures that the laser beam is automatically switched off whenever the distance between your skin and the laser is more than 10 centimetres. However, don't look right into the laser and do not use a Cosmetic Skin Laser on your eyes or eyelids.
