Doctors' Point

The Litou injection is not a treatment designed to fill wrinkles or add volume. It is classified as a “skin-nurturing treatment” that improves the skin’s overall condition, enhancing its firmness, radiance, and texture. This treatment is particularly effective for those who feel that their skin “looks tired lately” or that they “seem to have aged a bit.”

 

“What kind of treatment is the Lituo injection?” “How is it different from hyaluronic acid or Rejuran?” “Does it really improve skin texture?”—As skin boosters that focus on “building the foundation” of the skin gain attention, the Lituo injection is an advanced option that is increasingly being adopted in cosmetic surgery clinics.

 

While traditional cosmetic medicine was based on the concept of filling wrinkles or restoring volume, in recent years the idea of “skin nurturing” has gained popularity, and treatments that enhance the skin’s natural health and texture are becoming the main focus of cosmetic surgery.

 

In this article, from the perspective of a cosmetic surgeon, we will provide a detailed explanation—including before-and-after examples—of the characteristics of Rituo injections, their expected effects, injection methods, pain and downtime, recommended treatment frequency, and how they differ from Rejuran and hyaluronic acid. Based on evidence-based principles, we will also discuss key points to consider when choosing a clinic and important precautions to keep in mind.

The Role of Rituo Injections in Cosmetic Surgery

Rituo Injection is a skin booster formulation whose main ingredient is human acellular dermal matrix (hADM).

 

hADM is a biomaterial created by carefully removing cellular components from supplied human dermis while preserving the extracellular matrix (ECM), and it is expected to function as a “scaffold” that prepares the environment for skin regeneration.

 

In cosmetic surgery, it is positioned as a treatment that enhances skin texture while complementing procedures that alter shape (such as fillers and lifts).

What Is the Rituo Injection? Basics and Ingredients

The extracellular matrix contains a variety of molecules that support the structure of the skin. The main ones are as follows.

• Collagen

• Elastin

• Laminin

• Fibronectin

• Proteoglycan

These are the key players responsible for the dermis’s strength, elasticity, adhesion, and moisture retention. hADM, from which cellular components have been removed, is expected to reduce immune reactions and, by creating an environment within the skin that is “easier to rebuild,” works over time to improve firmness, elasticity, radiance, and skin texture.

 

In the skin care protocol used in cosmetic surgery, Rituo injections play a central role in the “foundation-building approach.”

Expected Effects and Indications

Rituo injections are expected to help improve the following skin concerns:

• Loss of firmness and reduced elasticity

• fine lines

• Dryness and Lack of Shine

• Enlarged Pores and Uneven Skin Texture

• Mild acne scars and rough skin texture

• Overall Improvement in Skin Condition Affected by Aging

This treatment is ideal for those who feel their skin “looks tired lately” or find that “foundation doesn’t go on well,” and we’re seeing an increasing number of consultations regarding this treatment at cosmetic surgery clinics where patients seek a natural, youthful appearance.

 

On the other hand, it is not suitable for improving deep wrinkles or noticeable sagging in a single session, and its role differs from that of volume-restoring treatments such as hyaluronic acid injections and thread lifts.

Mechanisms of Action Explained by Cosmetic Surgeons

The Lituo injection delivers ECM-derived components into the skin and promotes tissue remodeling by optimizing the cellular “environment.” The expected process is as follows:

• Optimizing the microenvironment that supports fibroblast function

• Provides a favorable scaffold for collagen and elastin production

• Supports the resolution of low-grade inflammation and facilitates the repair process

Therefore, rather than expecting immediate, dramatic changes, a gradual improvement in skin quality over a period of several weeks to several months is a more realistic expectation. In cosmetic surgery, careful scheduling based on this timeframe is considered essential.

Injection Methods and Selection Criteria in Cosmetic Surgery

The injection technique for Lituo is selected based on the patient’s skin condition, treatment area, and goals. In cosmetic surgery, we use the following approaches as appropriate.

Manual Injection

Doctors can finely adjust the depth, volume, and spacing for each area, making it suitable for delicate areas such as around the eyes, mouth, forehead, and neck. One of its advantages is that it can be customized for each individual, making it easy to treat areas with dynamic facial expressions.

Use with a cannula

Cannulas with rounded tips are easier to advance while avoiding blood vessels, and because they reduce the number of punctures required, they are expected to lower the risk of bruising. However, since their suitability depends on the site, it is important to use the appropriate needle and cannula for each situation.

Pain, Anesthesia, and Comfort

Although many people experience "a sharp, pricking pain," "a sensation of pressure during injection," or "a temporary stinging sensation," these are generally tolerable when combined with a topical anesthetic.

 

If you’re particularly anxious about pain, be sure to ask during your consultation at the cosmetic surgery clinic whether options such as nitrous oxide anesthesia can be used in combination with the procedure.

Downtime and Aftercare

As for downtime, you can expect redness, mild swelling, small bumps, pinpoint bleeding, bruising, and mild tenderness when pressed. These symptoms usually subside within a few days to 1–2 weeks.

 

On the day of the procedure, avoid strenuous exercise, alcohol, and long baths or saunas, and be sure to keep the area clean and well-moisturized. At a cosmetic surgery clinic, the post-procedure communication system and the availability of follow-up visits are also important factors that provide peace of mind.

Indications and Recommended Number of Treatments in Cosmetic Surgery

While some people notice a change in texture after just one session, if you’re aiming for stable and long-lasting results, we generally recommend a series of about three consecutive treatments spaced 3 to 4 weeks apart.

 

We then design a maintenance plan tailored to each individual’s skin condition. Taking into account age, lifestyle, and seasonal factors, our cosmetic surgery clinic will propose a schedule that works for you.

How It Differs from Other Skin Boosters and Fillers

Differences from Rejuran

Rejuran is primarily composed of polynucleotides (PN) and is designed to modulate biological processes through nucleic acids.

 

On the other hand, Rituo injections are based primarily on hADM-derived ECM and are designed to improve the tissue “scaffold.” Since their main ingredients and mechanisms of action differ, it is not a matter of which is superior; rather, it is essential to choose the appropriate treatment based on the specific concern, treatment area, and tolerance for downtime.

 

In cosmetic surgery, we sometimes adopt a combination strategy tailored to the season or upcoming events.

Differences from Hyaluronic Acid

The primary purpose of hyaluronic acid injections is to add volume and contour the face (such as nasolabial folds, temples, forehead, lips, and chin). In contrast, Lituo injections are intended to improve skin texture and are not a treatment designed to significantly alter facial contours.

 

Rather than competing with one another, the two approaches are complementary; in cosmetic surgery, we aim for more natural and refined results by designing “shape” and “texture” separately.

Who This Is Recommended For and Who It Isn't Suitable For

The following types of people are likely to be a good fit:

• I want to improve my skin's firmness and elasticity

• I want to smooth out fine lines, pores, and uneven skin texture

• I want to improve dryness and bring out a natural shine.

• I want my makeup to go on better

• “I want to prioritize ”natural rejuvenation”

On the other hand, for significant sagging or deep wrinkles along the jawline, a combination of treatments—such as hyaluronic acid, thread lifts, and energy-based devices—is often the most effective approach. Cosmetic surgery clinics will help you clarify your goals and propose the best solution, taking downtime and cost into consideration.

Safety, Contraindications, and Risk of Complications

Although downtime is relatively minimal, the risks associated with injectable treatments—such as bruising, swelling, infection, allergic reactions, and lump-like changes—are not entirely absent. The procedure may be postponed if you are pregnant or breastfeeding, have an active infection, or have inflammation at the treatment site.

 

Undergoing the procedure with a cosmetic surgeon who has a thorough understanding of anatomy—including the characteristics of the formulation, the injection sites, and the course of blood vessels—enhances both safety and patient satisfaction.

Before & After Guidelines (Changes Over Time)

Although results vary from person to person, mild swelling or slight puffiness may be noticeable immediately after the injection, but this generally subsides within a few days. You’ll begin to notice initial improvements in firmness and radiance within 2 to 4 weeks, and by the second or third session, you’ll likely start to see improvements in pores and skin texture—in other words, you’ll really start to feel your skin looking its best.

 

By comparing "Before" and "After" images taken under consistent lighting conditions to assess changes in brightness, uniformity, and how well makeup applies, it’s easier to track progress, which also helps in adjusting the protocol for future sessions.

Approach to Pricing and Plan Design

Costs vary depending on the dosage, treatment area, injection method, anesthesia, and aftercare plan. If you plan to undergo ongoing treatment, be sure to discuss the following during your consultation at the cosmetic surgery clinic: a comparison of the total costs between pay-as-you-go and package plans, and how to time treatments to achieve peak results in time for upcoming events.

 

The right number of times and appropriate intervals are key to determining the ultimate cost-effectiveness.

How to Choose a Cosmetic Surgery Clinic

Let's review the following points.

• Staff of physicians well-versed in anatomy and injection site planning (capable of providing protocols tailored to specific symptoms)

• Establishing Hygiene Management, Risk Disclosure, and Emergency Response Procedures

• Presenting "Before & After" images taken under standardized conditions and utilizing objective metrics (such as skin analysis devices)

• We can choose between the HydraFacial, manual injection, and cannula techniques, allowing us to provide highly satisfying treatment recommendations.

• Comprehensive Capabilities as a Cosmetic Surgery Clinic (Designing treatment plans that integrate with other therapies; flexibility to adapt to the seasons and special events)

In addition, the aftercare communication system, the ease of scheduling follow-up appointments, and a convenient location are also important. When choosing a cosmetic surgery clinic, keep in mind that it should be your partner in “ongoing skin care.”

Summary

The Litou injection is a new skin rejuvenation treatment that utilizes human-derived acellular dermal matrix (hADM) to optimize the skin’s regenerative environment. Unlike hyaluronic acid, which adds volume, or thread lifts, which are designed to lift the skin, this treatment aims to improve the skin’s own firmness, radiance, elasticity, and texture, thereby bringing out a natural, youthful appearance.

 

However, since this treatment is not designed to address deep wrinkles or significant sagging, combining it with hyaluronic acid injections, thread lifts, radiofrequency, or HIFU as needed can lead to greater satisfaction. Improving skin quality is not a one-time process; it’s important to nurture it over time by continuing with appropriate treatments.

 

If you're wondering whether Lituo injections are right for you, start by having a cosmetic surgeon conduct a detailed examination of your skin condition and discuss a treatment plan tailored to your specific concerns and lifestyle. A treatment plan based on a professional diagnosis is the fastest way to achieve natural, beautiful skin.
