*3.6.2 Renuvion for skin tightening and skin rejuvenation*

Renuvion may be used for skin tightening using tumescence anesthesia with or without liposuction. Different areas of applications commonly include jawline, submental region, posterior arms, trunk and upper medial thighs (**Figure 17**).

Pre (B) and post (C) procedure photographs of a 47 year old lady who wanted to drastically reduce her buttocks as they were in congruent with the shape of her legs. She underwent renuvion for the buttocks along with suction assisted liposuction to take out 5 liters of fat just from her buttocks. The post-operative photograph was taken 8 weeks after surgery.*

One of the main key points to achieve good tissue response and proper results with Renuvion® is to assess tissue thickness and depth. The thicker the treatment area is, the higher power and more passes are needed and vice versa. For example, treating submental region and jawline represents an area with thin skin and not significant amount of subcutaneous tissue as compared to the trunk. So, when treating the submental region and jawline, keep the power setting at 60% with Helium flow of 1.5–2 liters/minute and based on the thickness of the tissue perform 1 or 2 passes only. It is very important to avoid crosshatching in this area as this can cause thermal injury and disfiguring scarring of the neck. Staying in the superficial

subdermal plane is essential to avoid injury to the marginal mandibular nerve. It is important to keep in mind that thinner areas need less power and lower flow to avoid overzealous treatment.
