6D Traceless Double Eyelid is a new type of double eyelid technology, which is a minimally invasive medical surgery. This technology mainly uses thread embedding method to embed threads in the upper eyelids in a minimally invasive way, so that the eyes can form a perfect double eyelid effect. Compared with traditional double eyelid surgery, 6D traceless double eyelid surgery pays more attention to the precision and naturalness of the operation, and pursues traceless results after surgery. Although this kind of surgery is relatively safe, it is still recommended to choose a regular plastic surgery hospital or beauty institution and have a professional doctor perform the surgery to reduce risks.
