Non-surgical intelligent double eyelids are made of American high-density polypropylene spiral memory material and designed according to the principle of optimal mechanical distribution. After this material enters the eyelid tissue, it naturally forms along the curvature of eyelid and eyeball for 3-5 minutes at normal body temperature, without surgery, swelling, pain and sewing back and forth. Disposable products are safe, prevent the spread of diseases, firm and durable, beautiful and natural, recyclable and adjustable in width. They are the most advanced double eyelid molding technology in the world, with the least pain and the fastest molding speed. They can be molded once and remain unchanged for life, and can modify all kinds of failed double eyelids. Eyeliner and mascara can be applied on the same day, which is the most advanced double eyelid plastic surgery technology in the world. The disadvantage is that it can't handle the slack upper eyelid, which is not suitable for the elderly.
