Renuvion, Next-Generation Lifting for Skin Laxity

Key Takeaways

Renuvion 

Renuvion is a new alternative treatment for skin laxity.
It is a next-generation lifting solution designed for patients who are torn between the limited effectiveness of conventional lifting procedures and the burden of scarring from surgical excision.


This guide is especially helpful if:

  • You are concerned about skin laxity after liposuction and are hesitant about surgery
  • You did not achieve satisfactory results with existing treatments such as RF or ultrasound lifting
  • You are burdened by the scars and long recovery associated with excisional surgeries like facelifts or body lifts

The Dilemma of Skin Laxity Treatment– Excisional Surgery vs. Lifting Procedures

Before introducing Renuvion as a new alternative, let’s first examine the limitations of conventional skin laxity treatments.

Currently, skin laxity treatments are largely divided into two categories:

  • Excisional surgery: Removes excess skin through incisions for definitive results
  • Non-surgical lifting procedures: Less invasive and easier to undergo

Despite these options, many patients hesitate. Let’s explore why.

Reasons for Hesitating to Get a Lifting Treatment

Major types of lifting treatments include radiofrequency, ultrasound, laser, and thread lifting. Each method improves sagging skin either by delivering thermal energy to the skin layers or by inserting threads to lift the skin. Because these procedures do not require skin incisions, they leave no scars and allow for quick recovery, making them a popular choice for many people.

Although these options are convenient and relatively free, there are reasons why individuals with moderate skin sagging often do not achieve satisfactory results.

Why Patients Hesitate About Lifting Procedures

Common lifting treatments include RF, ultrasound, laser, and thread lifting. These methods deliver thermal energy to the skin layers or insert threads to improve laxity. Their major advantage is that they do not require skin excision, resulting in no visible scars and faster recovery. However, for patients with moderate skin laxity, these treatments often fail to produce satisfactory results.

Limitations of RF & Ultrasound Lifting

  • The optimal temperature for effective skin contraction is 85°C, where collagen contracts most efficiently and regeneration is stimulated.
  • The problem lies in heating speed. Conventional RF and ultrasound devices heat tissues gradually, affecting not only the target area but also surrounding tissues.
  • To ensure safety, these devices are limited to operating at 40–60°C, far below the optimal 85°C—resulting in limited tightening effects.

Limitations of Thread Lifting

  • While thread lifting does not use heat and avoids burn risks, it has fundamental limitations.
  • Threads primarily act on the superficial skin layers and have limited impact on deeper tissues and muscle layers.
  • As a result, it is often insufficient for moderate to severe laxity.
  • Over time, threads are absorbed or loosened, causing the lifting effect to diminish.
  • Typically, results last 6 months to 1 year,requiring repeat procedures.

Why Patients Hesitate About Excisional Surgery

Excisional surgery removes excess skin directly and pulls the remaining skin upward, making it the most effective option for severe skin laxity. Common examples include facelifts, abdominoplasty, arm lifts, and thigh lifts.

Despite its effectiveness, many patients are reluctant.

Visible Scarring

Because the skin is surgically excised, scars are inevitable. Scar location and size vary by procedure:

  • Facelift: scars along the front of the ear and hairline
  • Abdominoplasty: long horizontal scar above the pubic area
  • Arm lift: vertical scars on the inner arm
  • Thigh lift: scars in the inner thigh or groin

While scars fade over time, they do not disappear completely and may be visible in daily life. Skilled surgeons can design incisions to minimize visibility, for example, placing abdominoplasty scars below the underwear line. However, techniques vary by clinic, so thorough pre-operative consultation is essential.

Psychological Burden of Skin Excision

Excisional surgery permanently removes skin. Once removed, skin cannot be restored, which creates a significant psychological burden for many patients.

Next-Generation Lifting Device: What Is Renuvion?

The dilemma between visible surgical scars and insufficient lifting results led to the development of Renuvion.

Renuvion offers superior skin contraction compared to traditional lifting procedures while using only minimal incisions, making it a next-generation skin tightening solution positioned between non-surgical lifting and excisional surgery.

A Globally Proven Treatment: Renuvion

FDA Approval

    Renuvion is an FDA-approved medical device recognized for its ability to improve skin contraction and elasticity.

    It is specifically approved for preventing and improving skin laxity after liposuction.

Worldwide Clinical Validation

  • Renuvion is widely used across many countries as a skin laxity treatment.
  • It has established itself as an effective solution bridging the gap between lifting procedures and excisional surgery.
  • Since 2017, over 325,000 patients worldwide have undergone Renuvion treatment.
  • In a 2024 international physician survey, it was ranked as one of the most preferred body contouring technologies.
  • With continuous advancements, Renuvion has been introduced, offering improved performance.
  • In Korea, Renuvion is now available at Lydian Clinic, where the latest version is used to deliver enhanced results.

Renuvion Mechanism

Reaching the Optimal Skin-Contraction Temperature of 85°C

    Achieving Optimal Temperature While Minimizing Tissue Damage:

  • Conventional RF and ultrasound lifting gradually heat tissues, affecting surrounding areas and making it difficult to safely reach 85°C.
  • Renuvion uses helium plasma technology to rapidly reach 85°C and then cools the tissue within 1 second.
  • This rapid process allows precise contraction of the target tissue while preventing heat diffusion to surrounding areas.

Minimal Incisions, Minimal Scars

  • One of the biggest concerns with excisional surgery is scarring.
  • Renuvion is performed through tiny incisions, making post-treatment scars nearly unnoticeable.

Renuvion Before-and-After Photos & Recommended Candidates

Renuvion Before-and-After Photos

Renuvion effectively improves skin laxity caused by aging or post-liposuction and can be applied to multiple areas, including the face, neck, arms, abdomen, and thighs.

Recommended Candidates for Renuvion

Those Concerned About Skin Sagging After Liposuction

  • The ideal combination: Liposuction combined with Renuvion performed simultaneously.
  • This approach improves body contour while simultaneously enhancing skin firmness and elasticity.

Those with Moderate Skin Sagging

  • Patients who did not achieve satisfactory results from RF, ultrasound, or thread lifting
  • Those concerned about scarring and downtime associated with surgical lifting
  • Those seeking a solution between non-surgical lifting and surgical lift procedures

Minimal Scarring Through Smaller Incisions

  • One of the main reasons patients hesitate to undergo surgical lifting is long incision scars. In contrast, Renuvion requires only minimal incisions.

Those Experiencing Skin Sagging in Various Areas

  • Renuvion can be applied to all areas affected by skin laxity, from the face to the body.
  • Facial areas: Effective for patients with blurred jawlines and facial contours due to aging. Target areas include the jawline, double chin, cheeks, nasolabial folds, and neck wrinkles.
  • Body areas: Improves loose skin caused by weight fluctuations or aging. Target areas include the abdomen, arms, thighs, back, and bra line.

Lydian Clinic’s Total Skin Sagging Solution

  • Each patient experiencing skin sagging presents with different conditions and concerns.
  • For some patients, skin laxity may be mild and not require Renuvion, while for others, the condition may be severe and difficult to address even with Renuvion. In many cases, additional concerns such as stretch marks may also be present.
  • Lydian Clinic offers a comprehensive range of total skin laxity solutions to address these diverse conditions.

Stretch Marks Associated with Skin Sagging? What Is Lydian Clinic’s Treatment Approach

Causes of Stretch Marks

Stretch marks are a type of scar that occurs when the skin rapidly stretches, causing damage to collagen and elastic fibers in the dermal layer.

They occur due to pregnancy, rapid weight gain, or growth spurts.

Especially after pregnancy or rapid dieting, the skin goes through a process of stretching and then contracting.

Because of this process, skin sagging and stretch marks often appear together.

Stretch marks occur when the skin stretches, and skin sagging appears as the skin contracts.

Therefore, a significant number of people considering treatment for skin sagging are also dealing with stretch mark concerns at the same time.

Lydian Stretch Mark Treatment Recipe

The difficulty of treating stretch marks varies depending on their type.

High-difficulty stretch mark cases are usually long-standing white stretch marks.

Below is a brief introduction to Lydian’s main stretch mark treatment recipe.

First, Stem Cell Treatment

New cells are generated to regenerate the scar tissue known as stretch marks.

Growth factors secreted from stem cells fill the damaged tissue from within, restoring the skin to its original condition.

Second, Mirajet

In the case of long-standing stretch marks, damage has reached deep into the dermal layer.

At this stage, Lydian uses Mirajet to deliver medication deep into the dermis, improving stretch marks.

Third, Radiofrequency Treatment

Radiofrequency treatment delivers waves that reactivate damaged cells and stimulate them to function again.

Skin Laxity That Is Difficult to Treat with Renuvion: Surgical Lift

Surgical Lift – The Extent of Incision Varies Depending on the Degree of Sagging

  • In cases of severe skin laxity that cannot be adequately improved with Renuvion, surgical lifting is required.
  • However, not all surgical lifts are the same.
  • For example, in abdominoplasty , procedures are categorized into full tummy tuck, mini tummy tuck, and semi tummy tuck, depending on the location and severity of skin laxity.
  • As the names suggest, the extent of incision differs , meaning that it is not always necessary to excise the entire area unnecessarily.

Lydian Surgical Lift Designed to Conceal Incision Scars

  • One of the biggest concerns with surgical lifting is long and visible scars .
  • However, with an experienced medical team, scars can be designed to be as inconspicuous as possible.
  • At Lydian Clinic, abdominoplasty incisions are designed below the underwear or bikini line so that scars remain hidden even when wearing swimwear.
  • In addition, instead of suturing on the outer skin surface, we use internal dermal suturing techniques , allowing scars to heal from within the skin and preventing visible stitch marks on the surface.
  • These meticulous techniques help minimize scarring as much as possible.

Renewion FAQ

    Not necessarily. Renuvion can be performed together with liposuction or as a standalone procedure , depending on the patient’s condition.
  • Liposuction + Renuvion (simultaneous procedure) : The most ideal combination, allowing both body contour improvement and enhanced skin tightness at the same time.
  • Renuvion alone: Effective for patients who do not have significant fat but suffer mainly from skin laxity .
The key difference lies in temperature. Conventional lifting treatments: For safety reasons, they operate at 40–60°C, which limits the degree of skin contraction and tightening. Renuvion: Rapidly reaches the optimal skin contraction temperature of 85°C, producing significantly stronger tightening effects. Using helium plasma technology, Renuvion heats and cools tissue very quickly, allowing precise contraction of the target area while minimizing damage to surrounding tissues.
Renuvion is considered a mid-level alternative between non-surgical lifting and surgical lifting. Maintains the strengths of surgical lifting: Provides reliable improvement in skin elasticity. Compensates for the downsides of surgery: Uses minimal incisions, resulting in nearly invisible scars and much shorter recovery time. Ideal candidates: Patients with moderate skin laxity (Mild laxity → conventional lifting, severe laxity → surgical lifting recommended).
Yes. Renuvion has received approval from both the U.S. FDA (Food and Drug Administration) and the Korean MFDS/KFDA (Ministry of Food and Drug Safety). Renuvion is FDA-approved for use after liposuction and is authorized to contract subdermal soft tissue anywhere on the body. In addition to FDA approval, it has also received separate approval from the Korean regulatory authority, confirming both its safety and effectiveness.
The difference lies in the precision of energy delivery. Plasma lifting devices that use argon gas tend to have lower precision, which may increase the risk of thermal damage to surrounding tissues. In contrast, Renuvion uses highly precise energy control combined with rapid cooling, allowing it to achieve the desired lifting results accurately and safely within the target area.
