J-Plasma Renuvion Skin Tightening

J-Plasma Renuvion uses cold atmospheric helium plasma energy delivered subdermally to contract and tighten loose skin on the chest, neck, back, arms, abdomen, and legs — often performed alongside liposuction for simultaneous fat reduction and skin tightening. Can also be performed as a standalone procedure under local anesthesia. Addresses skin laxity from aging, weight loss, or pregnancy.

J-Plasma Renuvion is a minimally invasive skin tightening technology available at CG Cosmetic Surgery that uses cold helium plasma energy generated by a handheld probe inserted through small incisions beneath the skin surface. The device emits radiofrequency energy that excites helium gas flowing around the probe tip, converting it into a cold plasma state — a partially ionized gas that generates rapid, intense heating at the exact point of plasma formation. When the probe is passed in fanning motions beneath the dermis, this helium plasma causes immediate, visible contraction of the subdermal collagen matrix (the connective tissue fibers that anchor the skin to the underlying tissue), physically tightening the skin surface over the treated area within the same operative session. The mechanism differs from surface-applied energy devices such as external RF or HIFU, which work top-down and are limited in the degree of contraction achievable without damaging the overlying skin; because J-Plasma Renuvion delivers energy subdermal via the probe, it achieves greater and more immediate tissue contraction than surface devices can produce. The technology is most commonly used as an adjunct to liposuction at CG — following fat removal, the now-empty skin envelope may have insufficient elasticity to contract uniformly over the reduced tissue volume, particularly in patients over 40 or those with pre-existing skin laxity. J-Plasma Renuvion applied immediately after liposuction contracts the subdermal layer to conform more tightly to the newly contoured body. Treatment areas include the chest, neck, back, upper arms, abdomen, and lower extremities. For patients with purely lax skin and minimal excess fat, the procedure can also be performed as a standalone treatment under local anesthesia, making it an option for patients who are not candidates for excisional procedures. Price varies by area and combination.
