Can you use J-Plasma/Renuvion on top of the skin of the body as well as under the skin of the body?

Thank you for your question!  Yes, it can be used externally an internally as well. There are numerous non-surgical options available for your skin, and some can be used in combination to get best outcomes, but you would need a consultation with an expert.
Some options for skin tightening include:
- Thermage radiofrequency to heat the skin, tighten it over time, and prevent the aging process- Ultherapy high-intensity ultrasound to contract the muscle, tighten the face and neck, and prevent the    aging process- PDO NovaThreads or InstaLift threads for immediate lifting without surgery and long-term      collagen production- Sculptra injections for collagen production to areas of the face and neck with crepey skin or early      sagging- BTL Exilis Ultra, Venus Legacy, and Thermi250 for monthly collagen stimulation with facials- ThermiRF, Renuvion (J Plasma), or Inmode BodyTite for internal heating and tightening with or    without surgery- Fillers (or facial implants) to contour the jawline and chin to improve the appearance of the neck- Face lift / neck lift with fat grafting and fillers if you need a significant improvement- Incorporating medical-grade skincare products for use at home which can be found at    Emeragecosmetics.com along with a free consultation with one of my free Skin Care Specialists
I would suggest getting a formal evaluation with a cosmetic dermatologist. Best, Dr. Emer

Hello,
Thank you for your question. You are essentially getting at the difference between skin resurfacing, and skin tightening. In general, the former is beneficial for the face and the latter for the skin of the body. J-plasma over the skin of the body does not yield useful results.
Best wishes,

Thanks for your question.Due to the initial uses of Renuvion, body treatments for skin resurfacing has not been done at this time.  The thickness of the skin may pose some issues with current protocols.  The face will heal well.  There are many other technologies for the body that will provide good results.

Facial resurfacing with Reunion is a new technique with remarkable results. It also works very well for skin tightening (shrink wrapping) when used under the skin in multiple areas - abdomen, arms, knees etc. Using it over the skin in those areas will not tighten. The way the procedure tightens th skin has to do with contraction of the underlying element of the skin not just the skin itself. Great question though. Dr C
