Firmness, lumpiness and somewhat uneven results are common immediately after liposuction. This is typically at its worst between the first and third week. By six weeks, most firmness has dissipated. Final results take around three months.There are a few factors that can have an impact on this. When liposuction is done aggressively, lumpiness tends to last longer. This is also true when high-volume liposuction is performed.In general, the chin and neck area heal faster than other parts of the body. Lastly, if there is more blood left in the tissues after liposuction, then recovery can be delayed. Bleeding is kept to a minimum during liposuction by using tumescent solution correctly. I would expect significant improvement over the next few weeks after liposuction. Know your results will most likely change and hopefully improve over the next few months.Best of luck,Mats Hagstrom, M.D.
