Both CoolMini and Kybella permanently remove submental fat (the double chin), but they work in completely different ways. CoolMini freezes away the fat with no needles and no downtime, using an external handheld device. Kybella uses deoxycholic acid to destroy fat, an acid that naturally occurs in the body. Kybella is injected directly into the target area and requires about 20–50 injections per treatment. Kybella is more invasive and there’s more downtime, but some clients claim it works faster. Keep in mind that both CoolMini and Kybella require up to six months after your last treatment for final results, though you’ll see results from both much sooner than that.
