Unevenness after autologous fat filler is actually a very common phenomenon. There are various reasons that can cause the problem of uneven skin after fat filler, but the common reason is related to the surgeon’s technique, if the surgeon is inexperienced and has an unstable technique and does not control the amount of fat filler well, resulting in uneven filling, local excess or deficiency, uneven distribution of fat under the skin, excessive depression and convexity of some fat tissues The unevenness will be formed on the skin. It should be noted that the first few days after the operation, if the candidate finds that the filling site has unevenness, there is no need to worry too much, it is still in the recovery period and is a normal phenomenon. If the bump is obvious and the range is large, it is recommended to repair it by filling autologous fat for the second time to make it flat.
