Lithofine Nodules: Why Do They Form and How to Deal with Them?

Rituo Fine nodules refer to a side effect where the substance injected after the Rituo Fine procedure does not spread evenly but clumps together, feeling like a small lump under the skin. What we are referring to here is the clumping phenomenon that occurs in skin booster treatment areas, especially where the skin is thin, such as around the eyes or under the eyes.

First, let's start with a reassuring part. Rituo Fine has fine particles, so it is known to have a relatively low risk of clumping. However, 'low' does not mean 'none'. Depending on the injection depth, amount, dilution ratio, and the skill level of the performing hand, nodules can certainly occur. Therefore, in this post, we plan to slowly look at why they occur, what to do if they occur, and above all, how to experience them less in the first place.

🔍 What kind of treatment is Rituo Fine?

Rituo Fine is a skin booster whose main ingredient is the extracellular matrix (ECM) remaining after removing cellular components from donated human dermis. You can think of it as an injection treatment aimed at skin regeneration, elasticity, and moisturizing.

Within the ECM, there are collagen, elastin, glycosaminoglycans (GAGs), and growth factors. It is a concept of refilling materials similar to the structures our skin originally had. The average particle size is about 50 micrometers (µm), which is manufactured more finely than the standard Rituo product.

The fact that the particles are fine means it is highly advantageous for use in thin, sensitive areas. That's why Rituo Fine is introduced as a specialized product for cautious areas like around the eyes, under the eyes, and around the mouth. It is a segmented option considering the characteristics of the treatment area within the skin booster category.

📌 Key Summary: Rituo Fine is a skin booster specialized for around and under the eyes, featuring particles of about 50µm that contain human-derived ECM (collagen, elastin, GAGs, growth factors).

💢 Why do nodules occur?

The principle of nodules is simple. The injected substance does not spread widely but collects and clumps together as if hardening in one place. If it feels bumpy or like a pea when touched, you can suspect a nodule.

Most causes stem from procedure variables.

• Excessive injection volume: If too much is injected into a narrow area beyond what is needed, it will clump without room to be absorbed.

• Too shallow injection depth: If it goes in shallower than the dermis layer, it will clump near the surface and be felt or visible.

• Inappropriate dilution ratio: If the product concentration is incorrect, the dispersion will not be even.

• Practitioner's skill level: Ultimately, adjusting the depth, volume, and dilution to fit the area is a matter of human judgment.

Because the skin around and under the eyes is thin, these variables play a more sensitive role. Even with the same mistake, it shows up much more easily under the eyes than on a thick cheek. Therefore, it is no exaggeration to say that understanding the characteristics of the area is half of nodule prevention.

For reference, something that is easy to confuse with nodules is the embossing phenomenon. This is when the injected substance appears bumpy on the skin surface; while nodules are lumps that can be felt, embossing is closer to being visually prominent. Both are deeply related to shallow injection, and in reality, they sometimes appear together.

📌 Key Summary: Nodules occur when excessive injection volume, shallow depth, dilution errors, and lack of practitioner skill overlap, requiring special caution in the thin areas around and under the eyes.

🩺 How to deal with nodules if they occur?

If you suspect a nodule, your first priority is to contact the medical institution where you received the treatment to have the condition checked. Instead of making your own judgment and rubbing it hard or leaving it alone, you need to determine the direction of action by looking at the size, location, and depth of the lesion.

How to respond depends on the situation.

Here is one important point. Hyaluronidase (hyaluronic acid dissolving enzyme) is a drug used for hyaluronic acid (HA) filler nodules, so it may not apply directly to products with different ingredient compositions. Therefore, the approach of 'just dissolve it' does not always work for Rituo Fine nodules.

There are certainly cases where treatment is difficult. That is why preventing nodules from occurring in the first place is a much more realistic strategy than resolving them after they occur.

📌 Key Summary: If you suspect a nodule, consulting the hospital in charge is prior to self-treatment, and prevention is best since dissolving injections may apply differently depending on the ingredients.

🧬 Is it safe since it contains human-derived ingredients?

Some people worry about infection or emotional aversion because Rituo Fine is derived from donated human dermis. This is a completely natural reaction.

In the manufacturing process, it goes through a process to remove cellular components, a virus inactivation process, and rigorous infection testing. Since it is a method of removing cells and leaving only the structure (ECM), the risk of infection is known to be extremely low.

However, the approval status and conditions of the Ministry of Food and Drug Safety (MFDS) may vary depending on the product and timing, so we recommend that you directly verify before the procedure whether the product being used is officially distributed and managed. Just as much as the safety of the ingredients, 'where and how it is handled' determines the results.

📌 Key Summary: Although the risk of infection is low due to cell removal and virus inactivation processes, verification of approval and distribution status is required before the procedure.

⚖️ How does it differ from other eye skin boosters?

When looking for skin boosters for around and under the eyes, you will encounter various options other than Rituo Fine. The ingredient lines are slightly different.

It is difficult to say that any single one is absolutely superior. This is because the right choice varies depending on the skin condition, the desired direction, and the thickness of the area. There is skin for which an ECM-based approach is suitable, and there is skin that matches better with a DNA or PLA line.

Therefore, rather than choosing the product name first, the rational sequence is to verify what condition the area under your eyes is in through a consultation. Even at Onlif, when dealing with skin boosters, we approach according to the area and skin conditions rather than pushing a single correct answer. Since it is a method of assigning procedures that are familiar to hands in each field, we believe that the refinement of judgment is crucial, especially for sensitive areas like the thin eye area.

📌 Key Summary: Since Rituo Fine, Juveflux Eye, and Rejuran i have different ingredient lines, the selection criterion is 'does it suit my skin' rather than superiority.

✅ What should I check to reduce nodules?

Ultimately, prevention is key for nodules, and most of the prevention is decided during pre-procedure preparation.

• Check the thickness and characteristics of the treatment area together with the medical staff.

• Just asking how the injection depth and volume will be controlled changes the quality of the conversation.

• Checking in advance how they respond when a nodule occurs will put your mind at ease.

• Immediately after the procedure, do not miss early changes through sufficient hydration and monitoring of abnormal symptoms.

Contraindications for Rituo Fine treatment (pregnancy/lactation, immune-related conditions, allergies to specific ingredients, etc.) must also be discussed in advance. These conditions vary by individual and are hard to state uniformly, which is why in-person verification is all the more necessary.

Onlif does not aim for an approach that changes the shape of the eyes, nose, and mouth, but rather pursues non-surgical procedures that clear away skin concerns that mask one's natural impression. We believe that side effects like nodules are ultimately managed through an attitude of handling things carefully, without excess.

📌 Key Summary: Check the area characteristics, injection plan, response to side effects, and contraindications before the procedure, and take care of early changes through hydration and symptom observation after the procedure.

❓ Frequently Asked Questions

Do Rituo Fine nodules go away on their own, or is treatment absolutely necessary?

If they are small and fade along with initial swelling, they may improve over time. However, if they are large or persist for a long time, it is safer to have the condition checked at the hospital in charge rather than leaving it alone. Whether they disappear naturally depends on size, depth, and progress, so self-judgment is not recommended.

Between Rituo and Rituo Fine, which one has a lower risk of nodules?

Rituo Fine is manufactured with finer particles of about 50µm, so it is known to have a relatively lower risk of clumping in thin areas. However, there are no official statistics directly comparing the nodule occurrence rates of the two products, and nodules can occur with any product if the procedure is performed inappropriately.

Since it is an ingredient derived from the human body, is there any risk of infection?

The risk is known to be extremely low through a process to remove cellular components, virus inactivation, and infection testing. However, rather than concluding 'there is none at all', it is good to check before the procedure whether the product being used is officially managed and distributed.

Is there a way to check by myself if a nodule has formed?

If you feel a pea-like lump when gently touching the treatment area, or if a specific area continuously appears prominent, you can suspect a nodule or embossing. However, in the beginning, it is difficult to distinguish from swelling, so it is accurate to get it checked by a hospital if it remains the same after a few days.

Between around the eyes and under the eyes, which area has a higher risk of nodules?

Both areas require caution because the skin is thin. In particular, the skin under the eyes is extremely thin and has a lot of movement, making nodules or show-through easy to stand out during shallow injection. The injection plan for each area must be coordinated in a prior consultation.

Nodule side effects after Rituo Fine procedure, things that are good to check before choosing a hospital

Even with the same procedure, the results and recovery process vary depending on where, by whom, and how it is performed. Asking these items directly during the consultation will help you make a judgment.

• Is it a place that performs that procedure frequently? — Every hospital has different key procedures they focus on. Check if it is a place that regularly handles nodule side effects after Rituo Fine procedures.

• Can you check the products and equipment used? — Ask if you can verify the product name and whether it is genuine (whether it is an import-approved product, whether there is an unboxing verification process) during the consultation.

• Do they explain the cost breakdown? — Rather than just hearing the total amount, you need to hear an explanation of which product, how much, and on which area it is used to make a judgment.

• Do they design by looking at the entire face? — Even for the same procedure, the location and volume of injection vary depending on the face shape, skin condition, and left-right asymmetry.

• Do they explain adverse reactions and the recovery process first? — A place that informs you of possible adverse reactions and coping methods along with expected changes is better for making a judgment than a consultation that only speaks of expected changes.

• Is there a way to check progress after the procedure? — Check if the timing for progress checks, the method of contact when there is an issue, and the criteria for follow-up visits are established.

Onlif Clinic handles nodule side effects after Rituo Fine procedures like this
