Renuvion Skin Tightening: How Effective Is It for Sagging Skin?
Explains how Renuvion tightening works for sagging skin on the face and body, what to consider when combining it with liposuction, and what to expect during recovery.

Hello, this is Tangle Plastic Surgery Clinic.
For those concerned about sagging skin on the face and body,
today we will explain what to consider when combining Renuvion tightening with liposuction.
You may wonder whether reducing fat will also tighten loose skin.
In such cases, it is important to assess not only the amount of fat but also the degree of skin sagging.
Today, we will explain how Renuvion can be used to address both of these concerns.
The points to check differ by area for the face and body.
We will go through the principles of Renuvion, combined treatment with liposuction, and the recovery process in order.

Renuvion delivers energy to the tissue beneath the skin. |
Renuvion is a medical device that uses radiofrequency (RF) energy and helium to generate plasma.
It accesses the tissue beneath the skin through a small insertion site and uses heat-induced tissue coagulation and contraction.
Because the procedure involves inserting an instrument through a small incision, there is a possibility of scarring.
During your consultation, we will explain the procedure along with anesthesia, insertion sites, and the recovery process.
Tightening refers to improving the appearance of sagging skin by using this tissue contraction.
The changes you can expect vary depending on skin condition and the degree of laxity.
2. On the face, we examine sagging under the chin and in the neck.
If your jawline looks blurred or you are concerned about a double chin, we first check how much fat is present
and how far the skin has sagged.
Even when the appearance looks similar, the treatment plan differs depending on the cause.
Skin laxity in the neck and under the chin is an area where clinical studies have evaluated the effects of Renuvion.
The studies reported improvement at six months after treatment,
but individual results may vary depending on skin condition.
During your consultation, we will review the areas of concern and the changes you hope to see,
and determine whether Renuvion is appropriate for that area.

3. Treatment plans differ by area: abdomen, arms, and thighs
At Tangle Plastic Surgery Clinic, we look at the abdomen, arms, thighs, and back.
We examine skin laxity across various body areas and consult on whether Renuvion is appropriate.
If your skin has loosened after pregnancy or weight changes,
or if you are considering liposuction and are also concerned about skin sagging,
we check both the amount of fat and the condition of the skin.
Even within the same area, the appropriate treatment plan varies depending on the degree of sagging and tissue condition.
We will determine whether reducing fat should come first or whether skin laxity should be addressed at the same time,
and then explain a plan suited to each area.
4. Why combine it with liposuction?
Liposuction removes fat to adjust volume,
while Renuvion induces coagulation and contraction of the tissue beneath the skin.
If you are concerned about both fat and skin sagging, combining the two approaches may be considered.
The Renuvion APR handpiece has been cleared by the U.S. FDA for
subcutaneous soft tissue coagulation to improve body contour after liposuction.
The scope of clearance differs depending on the treatment area and purpose,
so domestic use should be confirmed against the approved indications in Korea.
Whether to combine treatments is decided after an examination, including whether to plan liposuction alone
or to also consider Renuvion. We will explain the expected changes and the additional risks of each option.
5. We also provide guidance on recovery and precautions.
It is difficult to judge the final result based solely on how things look immediately after treatment.
Changes should be monitored as recovery progresses,
and results vary from person to person even with the same treatment.
Recovery time depends on the treatment area and extent, and on whether liposuction is performed at the same time.
During your consultation, we will also review your schedule for returning to daily activities and how to care for yourself during recovery.
Pain and swelling may occur after treatment,
and there is a possibility of side effects such as burns, infection, changes in sensation, and scarring.
In rare cases, serious complications such as gas embolism may also occur.
Before treatment, we will explain these risks and precautions,
and advise you to contact the clinic immediately if any abnormal symptoms appear during recovery.
If you are concerned about sagging skin on the face or body,
we recommend starting with a consultation to check the amount of fat and the condition of your skin.
At Tangle Plastic Surgery Clinic, we will explain the changes you can realistically expect based on your current condition.
