Sylfirm X is a minimally invasive, non-surgical skin treatment that combines radio frequency (RF) heat and microneedling to treat skin laxity. It can be used to tighten and tone skin, reduce laxity, and rejuvenate the skin. Sylfirm X can be tailored to individual skin types and concerns, and can be used to treat loose skin on the whole body including abdomen, thighs, or buttocks.
