Will cryo therapy help after vaser lipo?

I would avoid doing this for a multitude of reasons.  You want to wait to see what the liposuction developed. Adding a secondary fat distractive treatment I'm top of this would lead to results that can't be deciphered.  If your liposuction was done correctly then you should not need an additional treatment.  People often retain numbness and a lack of sensation after liposuction.  The skins ability to auto regulate temperature may be altered. It certainly is early after liposuction within the first few days. This could lead to actual frostbite tissue necrosis from excessive cold or hot.  Unfortunately I've seen one case where someone literally cooked himself with a heating pad causing for thickness 30 green burns of their abdomen.  Cold and hot can both cause for thickness tissue necrosis. Check with your plastic surgeon. Best, Mats Hagstrom MD 

Hi and welcome to our forum!
You are most likely experiencing inflammatory swelling after your recent procedure. It will initially totally obscure the operative result. 60-80% will resolve within 6 weeks with the remainder slowly abating over 6 months or so. 
I would not advise adding another procedure so soon after your surgical procedure. The tissues are swollen, their blood supply has been "tampered with", and there may be added risks of infection or tissue loss. It will not accelerate the healing process....actually quite the opposite! Be patient...you may consider non surgical modalities after swelling subsides and the tissues become more hardy (3-6 months from now).
Best wishes...
