Swelling and healing as well as scar maturation can persist for 6 months and sometimes up to 1 year following liposuction. PSs have different post-operative protocols based upon their experience and training; some recommend adjustable garments; others, body boards and foam. I recommend following your PS's advice for the best recovery.
Nice0710 Short answer is no. Each surgeon has their own protocol for patient recovery after liposuction and usually most of us recommend some sort of an elastic garment to be worn at all times for the first 2 to 4 weeks after surgery. This allow quicker recovery from swelling and assists skin contraction. Uncomfortable back and abdominal boards are really unnecessary. Be certain to consult with a board-certified plastic surgeon in our area. Good luck.
