I went to get CoolSculpting done on my love handles today. Is it normal that only one side is slightly pink and not the other?

I wouldn't worry about different skin reactions to either side.  I had slight bruising on one side and not the other myself. 

Thank you for your question. This is not uncommon. Bruising, swelling, and redness can appear differently on each flank. This should subside with time. Speak to your chosen provider if you are concerned. Regards, 

CoolSculpting can cause bruising, swelling and redness. It is not abnormal to have discoloration on one side and not the other. I suggest SculpSure with Vanquish in the future as it has no downtime or risk of these side effects. We combine other treatments to get an improved outcome.  Best, Dr. Emer

It is possible to get some temporary discoloration of the skin after a CoolSculpting treatment.  Sometimes, this can be bruising, but it is also possible to get redness or a pink discoloration.  If discoloration occurs, it is not always on both sides or the same on both sides, so it would not be unusual for you to have one flank slightly pink and not the other.  

Each treatment area is different and can have different reactions.  You really can't compare different CoolSculpting areas.  As long as you did the full treatment, there is no need to worry.
