Can coolsculpting cause stretchmarks? Abdomen coolsculpted yesterday. (photo)

Don't worry! A little redness after CoolSculpting is perfectly normal and will not last. Because CoolSculpting reduces the volume of fat underneath the skin rather than adding to it, your skin is not stretched. 
 
CoolSculpting uses a patented technique called cryolipolysis to lower the temperature of a treated area enough to send fat cells into apoptosis (slow cell death), but not enough to have any permanent effects on skin, muscle, organs, or any other tissues. Some patients do find that they are tender, swollen and pink or red for a few days after CoolSculpting. If the redness lasts more than a couple of weeks, then please consult your board-certified dermatologist.

Thank you for your question. Coolsculpting does not cause stretch marks. What you may be experiencing is redness or bruising in the treatment area which are common side effects of the treatment. This may last up to two weeks. Please consult with your provider if you are concerned. Regards,

CoolSculpting will not affect skin integrity.  It can cause temporary bruising, swelling and redness.  These visible changes will usually go away after a couple of days.  But permanent changes like stretch marks are not a feature of CoolSculpting. 
What you have actually look like scratch marks.  Stretch marks will feel like divots or burrows when you run your fingers across the lines.  I suspect that you will see those lines gradually fade over the next few days.  
Hope this helps,
