The embedding method is to embed polymer thread or protein thread into the upper eyelid and fix the double eyelids in this way. The effect is generally only three to five years, but also more than ten years. However, the effect of double eyelids in this way is not ideal and can be modified.

Three-point positioning is to purposefully cut three tiny wounds on the double eyelids, remove some fat as needed, and form double eyelids after fixation. This technology has good effect, quick recovery and lasting effect.
