Doctors' Point

Re2O is a skin booster that’s gaining attention in South Korea, but rather than choosing it simply because “it’s popular in South Korea,” it’s important to determine whether it’s the right treatment for your specific skin concerns. Since this treatment is designed to improve skin texture, other approaches may be more suitable for addressing sagging or facial contouring. Be sure to compare factors such as the safety of the formulation, the doctor’s skill, and the aftercare support system to choose the treatment that’s right for you.

 

Re2O is a next-generation skin booster that has garnered attention in South Korea’s skincare culture. While treatments such as Rejuran, Jubelook, Profhilo, exosomes, and skin-nourishing injections have become widespread, Re2O stands out for its focus on building the foundation of the dermis.

 

We’ve been receiving an increasing number of inquiries from both people traveling to South Korea in search of the latest trends and those looking into how widely the treatment has been adopted at cosmetic surgery clinics in Japan. These inquiries include questions such as, “Should I get Rituo in South Korea?” “Is it safe to get it in Japan?” and “How is it different from existing skin boosters?”

 

In this article, from the perspective of a cosmetic surgeon, we provide a practical and impartial explanation of the ingredients and underlying principles, the expected effects, the benefits and precautions to consider when undergoing the procedure in South Korea, and the criteria to consider when evaluating the option in Japan.

What Is Re2O?: The Concept of Optimizing the Dermis’s “Scaffold”

Rituo is introduced as a skin booster that targets the dermis and the extracellular matrix (ECM), which form the foundation of the skin.

 

While typical skin boosters focus primarily on hydration and repair signals, Lituo aims to enhance firmness, elasticity, and smoothness by optimizing the structural components—such as collagen and elastin—as well as the surrounding ECM environment.

The goal is to take a multifaceted approach to restoring the balance of the dermis, which has been disrupted by aging, UV rays, inflammation, dryness, and lifestyle factors.

Why Lituo Is Gaining Attention in South Korea: Skincare Culture and High Aesthetic Standards

In South Korea, there is a large segment of the population that has made “skin care” a regular part of their lifestyle, and it is common practice to combine laser treatments, RF, Botox, and various skin boosters to continuously improve the overall texture of the skin.

 

Among those who have already tried Rejuran, Jubelook, and Profhilo, there is a need for a more structural approach, and Lituo meets that need.

 

Another factor is that South Korea has a fast pace of adoption, a wide range of options, and a diverse range of price points, creating an environment that makes it easy to analyze and compare trends.

Key Features and Design Philosophy: Our Role as an ECM Support Provider

The key term in this explanation is “ECM (extracellular matrix).” The ECM is composed of collagen, elastin, hyaluronic acid, glycoproteins, proteoglycans, and other components, and it supports the structure and elasticity of tissues.

 

Rituo is designed not merely to moisturize, but to regulate these structural elements, aiming to have a positive impact on skin firmness, elasticity, texture, and smoothness.

 

However, since the composition and behavior of the ingredients are also affected by the manufacturing lot, the injection site, and concomitant treatments, individualcosmetic surgeryThe insights and techniques gained there determine the outcome.

Expected Benefits and Limitations: Managing Unrealistic Expectations and Gaining an Accurate Understanding

• What to Expect: Improved firmness, radiance, and elasticity; more even skin texture; reduction of dry fine lines and crepey lines; less noticeable pores; and improved appearance of sagging skin
• Limitations: Does not physically lift significant sagging skin / Is not primarily intended for contouring or adding volume / The onset and duration of results vary significantly from person to person

 

Some people notice a difference after just one session, while others experience results through a gradual, cumulative process. Factors such as skin thickness, tendency toward inflammation, prior treatments, the injection depth and volume, combination therapies, and lifestyle all influence the results.

Differences Between Rejuran, Jubeluck, and Profilo (Organized by Function)

• Rejuran: Primarily composed of polynucleotides. Focuses on repair and soothing. It is often suitable for thin skin or skin prone to redness.
• Jubelook: Known for its combination of PDLLA and non-crosslinked HA, it stimulates collagen production to address pores, skin firmness, fine lines, and acne scars.
• Profilor: High-concentration hyaluronic acid. Aims to improve skin texture over a wide area through moisture retention and remodeling.
• Rituo: Strongly supports the "scaffold" of the ECM and dermal structure. A good option when prioritizing firmness, elasticity, and texture as a foundation.

 

The basic rule is to choose a treatment based on whether it addresses your specific skin concerns, rather than which one is considered the best. For complex skin concerns, a phased, multifaceted treatment plan developed at a cosmetic surgery clinic is effective.

The Benefits and Risks of Undergoing Cosmetic Surgery in South Korea

Advantages: A wide range of options, quick treatment, many medical facilities with expertise in skin care, and the ability to easily optimize costs through package deals. On the other hand, if you choose a provider based solely on price, the precision of the injection depth and design may be lacking, which could increase the risk of insufficient results, swelling, bruising, unevenness, and asymmetry.

 

When undergoing the procedure in South Korea, be sure to verify that the facility operates as a cosmetic surgery clinic (including whether the doctor performs the injections, as well as the quality of hygiene, storage, informed consent, and aftercare).

Checklist for Studying in South Korea (Practical Guide)

• Can the product name, manufacturer, packaging, lot number, expiration date, and storage conditions be verified on the spot (it is preferable to be present when the package is opened)?
• Is the practitioner a physician? What are the injection methods (manual injection, napage, cannula, or machine) and how is the injection layer designed?
• Does the plan specify which areas will be treated (the entire face, or with a focus on the eyes, cheeks, and mouth area) and explain the number of sessions required and the intervals between them?
• Symptoms of downtime (redness, hives, bruising, swelling, pain), their duration, and their impact on your travel plans.
• Means of communication after returning home and procedures for handling problems.

Downtime, Side Effects, and Contraindications

Expected symptoms: Redness, swelling, hives, bruising, tenderness or discomfort, and itching. In most cases, these symptoms subside within a few days to a week, though the duration may vary from person to person.

 

In rare cases, complications such as infection, hypersensitivity reactions, lumps or unevenness, inflammation, or effects on nerves or blood vessels may occur. If you are pregnant or breastfeeding, have severe allergies, an autoimmune disease, an active infection or dermatitis, a tendency to develop keloids, or are taking anticoagulant medication, please consult with your plastic surgeon to carefully determine whether the procedure is appropriate for you.

Who It's Suited For / Who It's Not Suited For

• Recommended for: Those concerned about loss of firmness, sagging, dry fine lines, visible pores, or thin skin. Those who have already tried a skin booster and are looking to further strengthen their skin’s foundation.
• People for whom this treatment may not be suitable: Those whose primary goals are to lift significant sagging skin, achieve a more defined facial contour, or see immediate improvement in deep wrinkles (a combination of thread lifts, HA injections, HIFU/RF, and surgical treatments may be necessary).

Key Points to Consider When Choosing a Cosmetic Surgery Clinic in Japan

• Confirm the approval status and source of supply, whether there are equivalent domestically approved products, and whether the product is eligible for the adverse reaction relief program.
• The physician’s experience with injections, design philosophy (injection site, layer, volume, and interval), treatment plan for combination therapy, and follow-up system.
• Planning and budget design based on the premise of phased maintenance, rather than a one-time, one-off effort.

In cosmetic surgery, it’s important to assess your skin during the consultation and set realistic expectations. Don’t just go by advertisements or trends—determine which procedures are truly necessary for your skin.

Our Clinic’s Approach to Cosmetic Surgery (Safety and Transparency)

• Injections Administered by a Physician: A plastic surgeon oversees the entire procedure. The course of major blood vessels is confirmed in advance using ultrasound (as needed) to minimize risks.
• Transparency of Medication Preparation: The packaging, lot number, expiration date, and whether the package has been opened are verified in the presence of the patient. Records of storage and temperature control are also available upon request.
• Customized Treatment: Based on skin thickness, tendency toward inflammation, and medical history, the injection depth and dosage are optimized for each specific area. When combining treatments such as laser, RF, or Botox, the total amount of stimulation is carefully managed.
• Comfort: We minimize the risk of pain and bruising by using a combination of topical anesthetic cream, cooling, and ultra-fine needles and cannulas.
• Follow-up: At the follow-up visit (typically 1–2 weeks later), we’ll check for changes in texture and any asymmetry, and make minor adjustments to the plan for the next session.
• Before & After Policy: Photos are taken under strictly consistent conditions (lighting, angle, facial expression). No editing or retouching is performed; images are presented only for explanatory purposes.

 

These principles apply not only to Lituo but to our clinic’s cosmetic surgery department as a whole.

Treatments That Are Easy to Combine and Scheduling

• Pore and Skin Tightening: Needle RF / Fractional Treatments (with controlled total stimulation).
• Sagging: Radiofrequency (RF) and HIFU target the subcutaneous to SMAS layers, while Rituo corrects the texture of the dermis.
• Treatment: Gradual, low-power pico laser and toning treatments.
• Expression Lines: Achieve a natural look with the minimum effective dose of Botox.
• Volume: Hyaluronic acid injections are limited to the necessary areas.

 

Since using multiple treatments on the same day increases the strain on the skin, we generally recommend a phased approach. In particular, for those prone to redness or melasma, we extend the intervals between treatments to ensure a wider safety margin.

How to Interpret "Before & After" Images: Key Points for Ensuring Fairness

• Are the shooting conditions (lighting, angle, facial expression, and distance) consistent?
• Is the number of days since the procedure clearly stated (to distinguish between the immediate swelling and the final results)?
• Is it disclosed whether the treatment is used in conjunction with skincare or other procedures?

 

Assessing the validity of "Before & After" comparisons can help prevent unrealistic expectations and mismatches.

Frequently Asked Questions (FAQ)

Q. Is there any pain?

A. You may experience a prickling sensation or tenderness due to the injection. We minimize any discomfort by using anesthetic cream, cooling, and carefully selecting the cannula.

Q. How many times is required?

A. It depends on your skin type and your goals. While some people notice a glow after just one session, a course of multiple sessions is generally recommended for skin improvement. A cosmetic surgeon will determine the appropriate frequency and number of sessions during your consultation.

Q. Which is better, Rejuran or...?

A. It’s easier to choose between them if you think of Rejuran as more focused on repair, while Lituo emphasizes the dermal structure and the foundation of the ECM.

Q. Is it okay to get it done cheaply in South Korea?

A. Don’t base your decision solely on price; instead, prioritize the clinic’s overall standards as a cosmetic surgery facility (including the doctors’ skills, hygiene, aftercare, and transparency regarding treatments).

Summary

Re2O is a skin booster that focuses on the extracellular matrix (ECM) and has been gaining attention in the South Korean aesthetic medicine field. It is expected to be an effective treatment for improving overall skin quality—including firmness, elasticity, skin texture, pores, and fine lines—by prioritizing the enhancement of the skin’s foundation.

 

However, since this treatment is not intended for face lifting or contouring, the way the effects manifest and the suitability of the treatment vary from person to person.

 

Furthermore, whether you undergo the procedure in South Korea or in Japan, it is important to thoroughly verify the quality and safety of the products used, the experience of the physician performing the procedure, and the aftercare system in place. By selecting the appropriate treatment based on your skin concerns and goals, and combining it with other cosmetic medical procedures as needed, you can expect more satisfying results.

 

Don't base your decision solely on trends; instead, consult thoroughly with a trusted doctor to develop a treatment plan that's right for you.
