Is this amount of redness to be expected 12 hours post CoolSculpting? (Photos)

I have seen the same degree of redness, in some patients, that you have 12 hours after the CoolSculpting treatment to your back.  This discoloration should resolve completely over time.  It does not appear to be a burn, based on your photos, but if you have any concern you should contact the physician who treated you.  

This amount of redness is not typical.  Bruising on the other hand would be considered a normal reaction.  Your coolsculpting provider should be using a gel pack to protect the skin before applying the applicator.  I would share these results with your coolsculpting provider and seek medical attention.Best of luck,Dr. Philip Solomon, Solomon Facial Plastic

While this amount of redness is probably a bit more than we see on average it certainly can occur.  It is often a result of small broken blood vessels secondary to the suction the applicator puts on the tissue.  It will resolve on its own and you will see daily improvement until it is gone probably in about a week or so.  
Thank you for the question.
All the Best,
