Tight, firm skin is a sign of youthful beauty. But as we age, skin begins to sag or loosen. Time in the sun, weight loss and pregnancy can cause this to worsen, and many people are looking for a way to regain the firm skin of their youth. Out of the many skin tightening and firming procedures available, both non-surgical and surgical, Renuvion, also known as J Plasma or J Plasty offers a minimally-invasive, outstanding treatment to revitalize the skin on almost any area of the body.

Renuvion Kirkland and Bellevue


At Tseng Plastic Surgery in Bellevue and Kirkland Renuvion is a cutting-edge technology that combines helium gas and radiofrequency energy. Together, they generate a substance called cold helium plasma. This is used within the skin to cause the skin to contract naturally, and dramatically stimulate the production of collagen. Collagen makes up the elastic, firm quality of the skin and is responsible for a tight but supple, youthful appearance.

Renuvion is an alternative to surgery for patients who are looking to firm their skin and who have minimal to moderate skin laxity, Renuvion provides long-lasting rejuvenation and revitalization of the skin, significantly tightening and firming. For those who are not ready for surgery and would like to avoid scarring and longer downtime, Renuvion may be a perfect choice.


  • Minimally invasive, short procedure time
  • Produces significantly tighter, firmer skin
  • Can treat many areas of the body
  • Very small incisions and minimal scarring
  • Only one treatment is needed
  • Compared with surgeries that achieve similar results, a short downtime
  • Provides a dramatic change: a more youthful, rejuvenated appearance


One of the many benefits of Renuvion is that it can be used on almost any part of the body. The treatment acts as a lift, providing similar results as a facelift or tummy tuck can, but not as significant results as surgery.

Renuvion Kirkland and Bellevue



Prior to your procedure with Renuvion Kirkland and Bellevue patients will meet with Dr. Tseng for a thoughtful consultation. He will examine your skin, discuss your concerns, medical history and goals for the procedure. Dr. Tseng will talk through the procedure in detail and ensure all of your questions are answered and that this is the right treatment for you. During your consultation, you will determine your target areas for treatment, which may include the face, abdomen, neck, legs, buttocks and back.


Dr. Tseng will numb the Renuvion treatment area with a local anesthetic. Once the area is numb, he will make a very small incision that is less than half a centimeter. Dr. Tseng will then insert the device under your skin. The device emits ionized gas and radiofrequency. Together these create cold helium plasma. As this is applied under your skin, it instantly begins to firm it up by simultaneously generating enough heat to contract the skin and melt fat as excess helium gas cools the area. This energy combination contracts the tissues just under the skin and causes the skin to tighten and firm itself up. The procedure time varies, depending on how many areas are being treated. Each area treated takes about 15-30 minutes.


After your Renuvion treatment Kirkland and Bellevue patients should expect to take about a week off to rest and recuperate after your treatment. Once the procedure is complete, you will have a compression garment to wear which helps to reduce swelling and limits fluid collection. After 5-7 days, most patients are able to return to light work or activities. Wait until you have the go-ahead from Dr. Tseng before doing anything more rigorous.


You will be able to notice tighter, firmer skin almost immediately. As the swelling subsides over the next month, you will be able to see the results better. However, Renuvion results are most apparent over time. For the next six to nine months, as more collagen is produced, you will see more dramatic, a significant improvement as the clock goes backward instead of forward on your skin. One of the best benefits about Renuvion, or J Plasty is that the results are very long-lasting, for a minimum of five years.
