Excessive underarm sweat can leave one feeling less than confident in social situations. For Oakville and Cambridge patients who are seeking a lasting solution to this concern, Oakville Plastic Surgery and Advanced Skincare is proud to offer ThermiDry™. This breakthrough radiofrequency device safely and precisely delivers heat energy to disable underarm sweat glands and deliver a solution for excessive underarm sweating.



 A professional consultation will determine your candidacy for ThermiDry™. The micro-invasive treatment involves the insertion of probes to target the axillary sweat glands. Radiofrequency energy generates heat until the optimal target temperature is reached in order to disable the sweat glands.



The ThermiDry™ treatment involves some mild discomfort during and after the procedure. Patients can return to normal activities immediately post-treatment, however, it is recommended to avoid exercise for a few days. Some patients experience temporary numbness, bruising, or swelling in the treated area for one to two days after the procedure.


How it works

The ThermiDry™ system is designed to deliver radiofrequency energy that heats the sweat glands to a specific target temperature that effectively destroys them. The device is designed to automatically adjust the energy output to safely and precisely heat the sweat gland to therapeutic levels without harming the surrounding tissues. The sweat glands in the rest of the body will continue to function as a cooling system for the skin. The final benefit is freedom from the embarrassment of excessive underarm sweat.
