Post op care following cosmetic surgery varies between surgeons. For liposuction, the duration of wearing the compression is dependent on the surgeon's experience and techniques. In my practice, I ask my patients to wear the garment for one week for the neck and 4-6 weeks for the body lipo.
Wearing the neck garment is challenging because of the social issues. Lifting the chin up will help to keep the tissues tight and could help to avoid longer compression.
