Will wearing a compression garment still affect lipo results after 2 weeks?

Every doctor has their own recommendations on post-op garments. In my practice, I have my patients wear a compression garments for at least 6 weeks if not longer. This helps the skin to adhere back down to the tissue and also helps with swelling. 

My patients wear the compression garment for a minimum of 6 weeks.  The most important time is definitely the first 2 weeks.  After that, they wear it for comfort.  Switching will not affect the results.  You will find that the garment makes your skin feel better for months after surgery.

Like many plastic surgeons I asked patients to wear a compressive garment for several weeks after liposuction. At the very least it gives them comfort. However there's no evidence that these devices have any influence on the final outcome.

I prefer to have my patients wear a compression garment 24/7 for the first 6 weeks because it definitely helps with the swelling and most patients like the feeling of extra support. 

How long a person wears a compression garment after liposuction is very much dependent upon how they are healing. My customary postop recommendations are for people to wear rather tight compression approximately 20 hours a day for the first three weeks and then lighter compression for approximately 12 hours a day for the next three weeks. At two weeks I feel the tissues have not completely healed and therefore would benefit from additional support to not only help create a smooth contour but also help with resolution of any residual swelling.
