Embedding dilator: embedding a silica gel "water bag" in the normal skin around the scar, then slowly injecting water through the injection pot, so that the surrounding normal skin gradually bulges, thus "growing" redundant skin, and then removing the scar and covering the wound surface with the redundant skin. Normal skin around the scar is generally used, so the color, texture and hair distribution of the skin after operation are basically consistent with the surrounding skin. It only takes about 2 months, and the above two methods will leave a thin and shallow trace in the short term after operation, but it will not be obvious after a long time. Which method is suitable for you depends on the expert meeting you in person.
