Skin Tightening (J-Plasma / Profound RF)

Skin tightening at Alinea Lipo NYC using J-Plasma (Renuvion) radiofrequency-assisted helium plasma and Profound RF microneedling. J-Plasma delivers subdermal plasma energy for immediate collagen contraction after fat removal. Profound RF uses macro-focused RF energy for deep dermal remodelling and lifting. Treats loose skin on the abdomen, arms, thighs, neck, and face. Board-certified surgeons in Midtown Manhattan.

Alinea Lipo NYC offers two distinct technology platforms for skin tightening, addressing different tissue depths and patient profiles. J-Plasma (Renuvion, Apyx Medical) is a subdermal device that delivers a combination of radiofrequency energy and helium plasma through a small cannula inserted beneath the skin. When the RF energy ionises the helium gas, it creates a plasma state that produces extremely rapid, high-temperature energy delivery followed by equally rapid cooling — a thermal event that causes immediate, controlled contraction of the collagen fibres in the subdermal connective tissue. The rapid heating and cooling cycle (which occurs in milliseconds) prevents thermal spread to adjacent tissues while causing up to 70% collagen fibre contraction within the immediate treatment zone. The result is a visible tightening effect that can be seen during the procedure itself and that continues to improve over three to six months as the thermal stimulus drives neocollagenesis. J-Plasma is particularly effective when applied immediately following liposuction, where the fat removal has created a void in the subdermal space that the contracted skin can then retract into — making it a powerful adjunct to Lipo 360 and other body contouring procedures for patients with mild to moderate skin laxity. Treatment areas include the abdomen, flanks, inner arms, inner thighs, and submental region. Profound RF (InVivo Therapeutics) is a fractional radiofrequency microneedling device that uses insulated needles to deliver macro-focused RF energy precisely at 1.5–3.5 mm depth within the dermis, creating controlled thermal zones that stimulate fibroblast proliferation, collagen synthesis, and elastin regeneration. Unlike surface RF devices, Profound's monopolar deep-delivery architecture reaches the fibromuscular system where structural tightening originates. Clinical studies have shown improvements in skin laxity comparable to surgical procedures with significantly less downtime. Profound RF is suitable for facial skin laxity (jawline, cheeks, neck), body skin laxity, and cellulite improvement, and can be used independently of surgical procedures for patients who prefer non-surgical tightening.
