It takes about 1 month to completely reduce swelling after laser fat dissolution. Most liposuction on the back is performed under general anesthesia or sleep anesthesia, and each operation has a recovery period. Only by doing a good job of nursing in the recovery period can we better reflect the surgical effect. Generally speaking, there may be some pain after liposuction 1-2 days, but the pain will gradually disappear after 3 days, which will not affect normal life and work. After 2-3 weeks, you can do slight muscle exercise and promote local recovery.
