Hello. I’m Wonjin Jo, the director of Chai Clinic, where I have been providing dermatological care in Hongdae for 10 years.
Fine lines everywhere, and my skin feels dry and rough…
There are so many types of skin boosters.
What makes Rituo different?

People considering Rituo often find themselves wondering about exactly this point.
To give you the conclusion first, Rituo works in a fundamentally different way from other skin boosters. As a result, it tends to involve less concern about nodules and its effects tend to last longer.
Once you understand the difference, it becomes clearer whether it is suitable for your skin and where you should receive the treatment.
Today, I’ll explain how Rituo differs from other skin boosters such as Rejuran and Juvelook, and how to receive it effectively.

Rituo’s principle: It is about “filling,” not “stimulation”
Most skin boosters work by stimulating the skin and encouraging it to “produce collagen on its own.”
(This is the principle behind various skin boosters, including Juvelook and Rejuran.)
Rituo (Re2O) takes a different approach.
It directly replenishes actual components of our skin, such as collagen and elastin.
You can think of it as rebuilding the foundation of skin that has become thin and sunken with age from the inside by adding real materials.
Because these are components that were originally present in the body, they tend to cause less concern about rejection and naturally take hold within the skin.
When the thinned inner layers are densely filled, the dermis becomes firm again, fine lines become less noticeable, elasticity improves, and dryness is reduced.

Rituo involves less concern about nodules and lasts longer
This is where one of Rituo’s major advantages comes in.
Treatments such as Juvelook use substances that “induce” collagen production. If they collect in a particular area, excessive collagen may be produced, which can lead to hard nodules.
Rituo, on the other hand, directly adds collagen components found in the human body, so there is relatively less concern about nodules caused by this type of abnormal overgrowth.
For this reason, it is also generally used with relatively little burden in thin areas such as under the eyes and around the mouth.

The difference becomes even clearer when comparing it with Rejuran.
Rejuran tends to be quite painful,
whereas Rituo is less painful and, after completing the recommended number of treatments—usually three—the effects tend to last for six months to more than a year.
(Rituo is usually administered with a cannula, which is a needle with a blunt tip.

In the photo above, the item on top is a needle, and the one below is a cannula. The tip is blunt, right?
Rejuran can be quite painful because it is inserted through the dense dermal layer. With Rituo, the injection method itself is much smoother and less painful.)
Because it fills the tissue itself rather than stimulating it, the effects tend to last longer.
Skin types for which Rituo is effective
-
People whose skin has become thinner and who are beginning to notice fine lines and dryness
-
People whose loss of elasticity makes their pores appear vertically elongated
-
People whose skin feels dry and rough, causing makeup to sit on the surface
-
People who find fillers burdensome but want a feeling of being filled from within
However, to be honest, if you are trying to fill deeply etched wrinkles or sunken volume all at once, Rituo alone may not be sufficient.

The volume may be filled temporarily, but that volume does not continue to last.
The results of Rituo ultimately vary depending on how well the injected skin components take hold.
When we sow seeds in a field, not every seed sprouts and produces fruit, right?
Similarly, some of the Rituo material may settle and become part of your skin, while some may not.
Filling volume to the extent desired is the role of fillers, so when the purpose is different, it is appropriate to recommend a different treatment.

How to receive Rituo effectively
Rituo is a treatment involving less concern about nodules, but that does not mean it can be injected arbitrarily.
The results and natural appearance depend on the practitioner’s ability to place it evenly at the correct layer.
In particular, if it is injected too superficially in thin areas such as under the eyes and around the mouth, the material may show through and appear raised.

That is why the technique of evenly spreading it through the lower dermis using a blunt-tipped cannula is important.
The dosage must be allocated according to each treatment area based on your specific concerns, with the balance adjusted before injecting it evenly.
For this reason, choosing a clinic with extensive experience in filler or skin-booster treatments and a practitioner with strong technical skills may also be an option.

When choosing a clinic, you should therefore look for the following three things.
- Do they provide an honest diagnosis of whether Rituo is right for your skin—or whether Rejuran, Juvelook, or fillers would be more suitable?
- Do they explain the distribution plan and injection method for each area of concern?
- Do they accurately explain the practical effects this treatment can have on your face without exaggeration?

Summary
In summary, Rituo treatment in Hongdae involves less concern about nodules and tends to last longer. It is a skin booster that builds the foundation of the skin by replenishing its actual components to address fine lines and dryness.
Even with good ingredients, the results ultimately depend on which layer they are placed in and how they are injected.
I recommend discussing whether Rituo is right for your skin and how it should be used to replenish it during a consultation.
Thank you. This was Wonjin Jo.
