CoolSculpting,
Thank you for your great question! It is not advised to place a CoolSculpting applicator over the Nexplanon birth control implanted device. You could CoolSculpt other areas of your body, but not over the implant. You would have to remove the implant from you arm prior to CoolSulpting your arms. I do hope this information is helpful.
You can not get Coolsculpting over an implant. It would need to be removed prior to having a procedure
