Can I get CoolSmooth/coolsculpting done even if I am taking Yaz birth control?

Thank you for your question. Coolsculpting is a very safe procedure. However, all treatments have potential side effects, although with Coolsculpting they are very unlikely to occur. Your treating physician should discuss all potential side effects and expectations before your procedure. I hope this helps!
