**7. Conclusion**

The Renuvion helium plasma facilitates rapid delivery of high intensity radio frequency energy with rapid cooling to tissue to achieve significant tissue contraction with diminished risk of thermal spread and collateral injury. This versatile tool has many powerful applications in rejuvenation of the head and neck and can be used both subdermally as well as for ablative resurfacing to accomplish significant skin contraction and wrinkle reduction. Deeply etched wrinkles will be erased and the skin contraction of the upper lip and forehead is worth noting. The subdermal application affords a lift of the jowls and neck without having to perform a deep plane lift which can cause skin bunching in temporal area when there is excess redundant skin. This technology requires a thorough understanding of how the energy delivery effects change to the tissue and is highly user and technique dependent. Once more research has been done regarding the settings - optimal energy, flow rates and number of passes based on patients'skin types, then a consensus of treatment methods can be decided.
