All skin tightening and cellulite treatments performed by ZendyHealth providers are non-invasive and FDA-approved. Although they all can be quite effective if multiple sessions are performed, the true difference lies in the methods used to tighten the skin and reduce cellulite. Below are some of the most popular treatments, grouped by type of method: Thermage, Accent, Exilis and similar systems use a handheld device to deliver radiofrequency energy to the inner layer of the skin, while the outer layer is protected with a cooling spray. Velashape, Viora and similar devices use a combination of infrared light, vacuum technology, and radiofrequency energy to reduce cellulite with heat. Titan, SkinTyte, and similar devices deliver pulses of infrared light to the deeper skin tissues to tighten and stimulate collagen production, while the epidermal layer is cooled throughout. Venus Freeze and similar systems combine radiofrequency energy with magnetic pulses to target the inner layer of the skin.
