Doctors' Point

Unlike treatments like hyaluronic acid, which add volume, Rituo is a skin booster designed to improve the skin’s overall texture—including firmness, radiance, and texture. Therefore, if you are looking to improve deep wrinkles, noticeable sagging, or a lack of volume in the facial contours, Rituo alone may not be sufficient.

 

The key is to identify the root cause of your skin concerns and choose the appropriate treatment—including hyaluronic acid, Botox, and radiofrequency therapy—based on your specific needs. Additionally, the timing of results and the number of sessions required vary from person to person. Rather than choosing a treatment simply because it’s trendy, it’s important to consult with your doctor to determine whether it aligns with your skin condition and goals, and then develop a treatment plan that’s realistic for you.

 

In recent years, the mainstream approach in cosmetic medicine has shifted toward improving skin quality itself to achieve natural rejuvenation, and skin booster treatments have come into the spotlight. In this article, based on insights from cosmetic surgery, we’ll clarify “what Rituo is” and systematically explain its ingredients, effects, characteristics, indications, and precautions. We will also provide a comprehensive overview of how it compares to other treatments in cosmetic surgery, strategies for combining it with other procedures, and key considerations before undergoing the treatment.

 

Re2O, a popular product from South Korea, is positioned as a next-generation skin booster that focuses on improving the skin’s “environment,” unlike traditional fillers that simply add volume. We’ll answer the question “What is Re2O?” in an easy-to-understand way, drawing on the perspective of a cosmetic surgeon.

The Background Behind the Rising Popularity of Skin Boosters

• Growing demand for procedures with minimal downtime that do not involve surgery or major changes
• The growing acceptance of a regenerative medicine-based philosophy that focuses on “nurturing the skin” rather than “filling in wrinkles”
• A growing focus on skin texture—including radiance, firmness, elasticity, and skin texture—

 

Amid these trends, understanding “what Lituo is” is the first step toward making a wise choice about treatment.

What Is Re2O? Definition and Basic Concepts

Re2O is a skin booster developed in South Korea, formulated primarily to improve the condition of the dermis. Rather than aiming for explicit volume enhancement like hyaluronic acid fillers, it is based on a design philosophy that promotes comprehensive skin-beautifying effects, such as hydration, support for the skin’s barrier function, control of micro-inflammation, and optimization of the fibroblast environment.

 

Please note that specific formulations and specifications may vary depending on the country of origin, date, and lot; therefore, be sure to check the latest product information before receiving treatment.

Components and Design Philosophy (Based on Publicly Available Information)

Based on publicly available information and general knowledge about skin boosters, many formulations are designed to combine the following elements.

 

Multi-layered moisture retention achieved through moisturizing polymers with varying molecular weights; improvement of the skin’s condition through a blend of amino acids, vitamins, and peptides; protection against oxidative stress via antioxidant and skin-conditioning ingredients; and adjustment of diffusion and retention properties during application through optimization of pH and viscosity.

 

It may be easier to understand Rituo if you think of it as a formulation designed primarily to balance this “microenvironment surrounding the skin.”

Expected Effects (Results may vary)

• Enhanced Luster and Transparency: Optimized moisture retention leads to a lustrous, dewy appearance.

• Supports Firmness and Elasticity: By optimizing the dermal environment, it promotes supple firmness.

• Skin Texture and Minimized Pores: As the skin's surface becomes more even, the overall smoothness of the skin may improve.

• Reduction of Fine Lines Caused by Dryness: By supporting moisture retention and the skin's barrier function, fine lines may be softened.

• Improved makeup application: In some cases, as skin hydration and the condition of the stratum corneum are balanced, makeup adheres better.

 

These are merely general trends based on reported data, and results may vary from person to person depending on factors such as age, skin type, lifestyle, and history of other treatments. During your consultation at the cosmetic surgery clinic, let’s work together to establish realistic expectations tailored to your skin.

Illustration of the Mechanism of Action

By administering small amounts of the formulation in small, localized doses into the dermis, the goal is to enhance the skin’s overall “functioning capacity” by promoting local moisture retention, controlling mild inflammation, and optimizing the environment for fibroblast activity.

 

A key feature of this treatment is that it gently harnesses the initial response to wound healing, while also being designed to complement other energy-based devices and injection therapies commonly used in cosmetic surgery.

Differences from hyaluronic acid fillers and other skin boosters

• Hyaluronic acid fillers: Treatments that fill in furrows and add volume. They are suitable for contouring and treating deep wrinkles.
• Rituo: Designed to improve skin texture across the entire face. Targets “texture” elements such as radiance, firmness, and skin texture.
• Other skin boosters (e.g., PN/PDRN-based, Profhilo-based, etc.): Their formulations and diffusion properties vary, resulting in slight differences in the final texture and indications.

 

Among these options, Rituo can be seen as the choice that aims to provide “natural, even hydration and firmness.”

Who Is It For? Examples of Suitable and Unsuitable Candidates

Who is Rituo best suited for? From a cosmetic surgery perspective, it is generally considered a good fit for people with the following needs:

Characteristics of People Who Are Suited for This

• I want to comprehensively restore my skin's radiance, texture, and moisture.

• I’m looking for a natural, youthful look rather than one that looks “forced.”

• I'm concerned about fine lines and the crepey texture caused by dryness.

• I want to get my skin in good condition before the event (I recommend leaving plenty of time in your schedule).

• I don't need to add volume with fillers, but I want to improve the overall texture.

Caution Required / May Not Be Suitable

• Women who are pregnant or breastfeeding, those with a history of autoimmune diseases, or those with active, severe dermatitis.

• People who are prone to keloids or have a history of difficult-to-heal wounds.

• People at high risk of bleeding or internal bleeding due to oral anticoagulants or other reasons (consult your doctor).

• Individuals whose primary goal is to add volume to their facial contours (fillers are the preferred treatment option).

The decision on whether a procedure is appropriate depends on each individual's circumstances. Based on a consultation and diagnosis at a cosmetic surgery or cosmetic dermatology clinic, carefully weigh the balance between safety and effectiveness.

Procedure Flow (Standard for Cosmetic Surgery)

The general procedure is as follows: 1) Consultation and examination 2) Facial cleansing and photographic documentation 3) Topical anesthesia 4) Injection (manual or machine-assisted) 5) Cooling 6) Aftercare instructions 7) Follow-up appointment. In cosmetic surgery, we standardize hygiene management, medication management, pain management, and record-keeping (including “Before & After” documentation) to ensure consistent treatment outcomes.

Number of Times, Frequency, and Maintenance

Initially, a course of 3 to 4 sessions, spaced 3 to 4 weeks apart, is often recommended. After that, maintenance treatments every 3 to 6 months are considered, depending on the condition of your skin.

 

Some people notice results within a few days to a few weeks, while improvements in skin texture tend to develop gradually over several sessions. The specific schedule will be customized for each individual at the cosmetic surgery clinic.

Downtime, Side Effects, and Risks

• Immediate redness, hives, and pinpoint rash: These symptoms typically subside within a few days.

• Bruising: It usually resolves within about 1 to 2 weeks (results may vary by individual).

• Pain, tenderness, and a sensation of swelling: These are typically mild to moderate, and patients are often monitored.

• In rare cases, allergic reactions or infections may occur: Early detection and prompt treatment are crucial. If symptoms are severe, seek medical attention immediately.

Be sure to disclose your allergy history, history of treatment at other clinics, and any medications you are currently taking. In cosmetic surgery, we place great importance on medical interviews, hygiene measures, the selection of instruments, and post-operative follow-up to minimize risks.

Aftercare (Basics of Cosmetic Surgery)

• On the day of the procedure: Do not rub the area; avoid saunas and strenuous exercise. Keep the area clean.

• For a few days: Be sure to moisturize and use sunscreen. Temporarily discontinue the use of retinol and strong acidic peels.

• Makeup: It’s best to avoid the bruised areas and start applying makeup again the next day or later, beginning with a light application.

• In case of complications: If you experience swelling, pain, fever, or pus, contact the plastic surgery clinic as soon as possible.

How to Choose a Cosmetic Surgery Clinic and Key Considerations

Even with Rituo, results may vary from clinic to clinic. Patient satisfaction depends on the doctor’s injection plan, choice of equipment, hygiene and record-keeping practices, and aftercare policies. Given that this is a private medical service, it’s wise to choose a cosmetic surgery clinic that provides clear and transparent information.

How to Interpret "Before & After" Images

・Check for consistency in lighting, angle, facial expressions, and skin preparation (moisturizing and makeup). ・Note the timing of the photos (immediately after, one week later, one month later, etc.). ・Pay attention to changes in skin texture (luster, skin texture, pores, and fine lines). ・Read the accompanying text (number of sessions, combined treatments, downtime) as well. In official cosmetic surgery publications, clearly stated photography conditions and consistency in the progress reports serve as indicators of reliability.

Items to Confirm During Counseling

• Adaptation and Goal Setting: What can be improved, to what extent, and what are the alternatives?

• Frequency, Intervals, and Combination Therapy: A Realistic Plan and the Division of Responsibilities for Home Care.

• Risk Management: Protocols for Infection Prevention, Bruising Prevention, and Allergy Management.

• Cost: Total amount (initial course + maintenance), cancellation policy, and whether there are any additional fees.

Average Prices and Cost Estimates

Since this is a private medical service, costs can vary, but as a general guideline, each session typically ranges from the upper tens of thousands to around 100,000 yen. The total cost may vary depending on whether you opt for a multi-session package or combination therapy.

 

Since cost-effectiveness varies depending on skin concerns, treatment priorities, and desired results, obtaining a preliminary estimate from a cosmetic surgery clinic and setting clear goals are key.

Comparison with Other Treatments and Combination Strategies (From a Cosmetic Surgeon’s Perspective)

• PN/PDRN-based: Designed with a focus on regeneration, they share a similar goal of improving the skin’s overall condition. They differ in terms of spreadability and texture.
• Profhilo-type: Characterized by its tendency to spread. There are also cases where patients can easily feel the firming and tightening effects.
• Skin Botox: Effective for reducing pore size and shine, but its muscle-relaxing effects must be carefully assessed

 

Rituo is an option for “texture tuning” that can be used in combination with or as an alternative to these other treatments. In cosmetic surgery, we design a treatment plan that assigns specific roles to each: hyaluronic acid for filling in facial contours, Rituo for texture enhancement, and HIFU/RF for treating sagging.

Typical Examples of Combined Use

• Improved overall skin texture (Retuo) + support for deep wrinkles (hyaluronic acid).

• Sagging (HIFU/RF) + Hydration and Radiance (Rituo).

• Sebum and Pores (Small Amount of Botox) + Skin Texture Improvement (Rituo).

• Uneven Skin Tone (Light Therapy / Topical) + Moisture Retention & Barrier Support (Rituo).

Q&A: What Is Rituo? Frequently Asked Questions

Q. Is this available in Japan?

While some cosmetic surgery and dermatology clinics are beginning to offer this treatment, availability varies by clinic. Be sure to receive an explanation regarding its classification under the Pharmaceutical and Medical Devices Act, import channels, and quality control measures (such as storage temperature and expiration dates), and complete the consent procedures required for this treatment, which is considered an out-of-pocket service.

Q. When do the effects start, and how long do they last?

Some people may notice changes in their skin’s radiance and texture within a few days to a few weeks, and in many cases, these effects become more pronounced after the initial treatment course. How long the results last varies significantly depending on skin type, lifestyle, skincare routine, and any other treatments being used. Having a cosmetic surgery clinic help you plan your maintenance schedule can help you achieve more stable results.

Q. Is there any pain or downtime?

While most people can tolerate the procedure with topical anesthesia, you may feel a slight stinging sensation from the needle or the pressure of the injection. Small red spots, welts, and bruising are temporary and typically subside within a few days to one or two weeks.

Q. What about makeup, exercise, and bathing?

On the day of the procedure, avoid exercise that involves intense friction or sweating, as well as long baths and saunas. Resume these activities the next day or later, depending on how you feel. Apply makeup from the day of the procedure through the following day as directed by your doctor. Be sure to use adequate sun protection and moisturize thoroughly.

Summary

Re2O is a skin booster that aims to enhance the skin’s “texture”—such as radiance, firmness, and skin texture—by optimizing the skin’s environment, rather than altering its shape through volume. It complements hyaluronic acid and energy-based devices well, making it a suitable option for those seeking a natural, youthful appearance.

 

That said, results and downtime vary from person to person, and satisfaction is greatly influenced by the cosmetic surgery clinic’s operational practices—including product specifications, techniques, hygiene, and aftercare.

 

“Is Lituo right for me?” “How many sessions will it take, and what kind of results can I expect?” “What’s the best combination with other treatments?” The answers to these questions vary widely depending on your skin type, lifestyle, and goals. The surest path to success is to work with a trusted cosmetic surgery clinic to carefully discuss your suitability, the number of sessions needed, costs, and risks, and to develop a realistic plan.
