Hello.

This is Objet Plastic Surgery.

As summer draws closer, more and more people find that their skin condition no longer feels the same.

In winter, dryness was the main concern, but these days there is much more to manage, from excess shine and enlarged pores to makeup that breaks down easily.

When skin becomes tired so quickly, a skin booster is often considered.

Among them, an increasing number of people are visibly weighing Rituo and Rejuran against each other.

Their names may sound similar, but the two procedures differ from the way they work onward.

That is why, when it is time to choose, it is natural to hesitate over which one to select.

Today, with summer in mind, we will go through the criteria for considering these two procedures,

and the reasons behind that choice, one by one.

If you stay with us until the end, you will be able to assess for yourself which option may suit your skin.

When it comes to summer,

the answer is closer to “Rituo”

Let me start with the conclusion.

When comparing Rituo and Rejuran with the summer season alone in mind, the answer is somewhat closer to Rituo.

To understand why, we first need to look at how the two procedures differ.

Rejuran is a skin booster based on an ingredient called PN.

PN is known to help create an environment that supports regeneration within the skin and assist with collagen production,

thereby helping the skin recover on its own.

Put simply, it is more like encouraging the skin, saying, “Let’s get our strength back.”

Rituo, on the other hand, approaches the skin from a somewhat different direction.

Its focus is on replenishing the components that make up the skin’s structure.

Rather than offering encouragement, it is more focused on helping fill in what has become lacking.

There is one point worth noting here.

In summer, ultraviolet rays, heat, and air-conditioned environments alternate, which can cause the structures that support the skin to become tired more easily than usual.

When the structure itself is under strain, while waiting for regeneration signals,

an approach that replenishes depleted components may also be helpful.

This is precisely why Rituo comes to mind first in summer.

Let’s take a closer look at the ECM

that draws attention to Rituo

To understand Rituo, we need to discuss the term ECM at least once.

ECM is known as a structure that fills the space between cells and supports the skin.

When there is sufficient ECM, the skin can appear firm and full,

but as we age or external irritation accumulates, the ECM may gradually decrease.

Rituo is a skin booster based on ECM

that acts on the dermal layer and may help replenish the components needed for the skin’s structure.

Through this process, it helps create an environment where the skin can become fuller,

and as its density increases, thin, weakened skin may feel somewhat firmer.

During this process, you may also expect changes such as looser pores appearing more refined and the skin’s texture becoming smoother.

It is easy to think of Rituo and Rejuran as the same type of procedure,

but the ways they approach the skin are fundamentally different.

This is also why such changes can be welcome during a season like summer, when the skin becomes tired easily.

So which one should you choose?

The answer lies in “your skin”

After reading this far, you may think that Rituo must be the answer in every case.

That is not necessarily so.

Which of Rituo and Rejuran is better suited to your skin will differ from person to person.

Just as the right size of the same clothing differs from person to person,

the procedure that suits the skin also differs for each individual.

If you need an approach that enhances the skin’s ability to recover on its own,

Rejuran, which provides regeneration signals, may be a better fit.

On the other hand, if both elasticity and density have decreased,

Rituo, which replenishes components of the skin’s structure, may be helpful.

Ultimately, what matters is not the procedure that is currently popular, but the condition of your skin today.

Only after examining your skin thickness, elasticity, pore condition, and recent changes in its overall condition,

does the answer that suits you begin to become clear between Rituo and Rejuran.

Today, we reviewed together the criteria for considering Rituo and Rejuran as summer skin boosters.

Rejuran provides regeneration signals to the skin and helps it recover on its own,

while Rituo is focused on replenishing the components needed for the skin’s structure based on ECM.

We also discussed that during a season like summer, when the skin becomes tired easily, this replenishing approach may be helpful.

However, please remember that the real answer lies not in trends, but in the current condition of your skin.

Director Park Si-hyun of Objet Plastic Surgery examines your skin type, its condition on the day, and changes that vary with the season,

then provides a personalized recommendation for the direction best suited to your skin now, between Rituo and Rejuran.

Especially in summer, we carefully consider both the irritation the skin receives and the recovery process that follows,

and help determine an approach so that a single procedure can continue comfortably throughout the season.

If you are considering Rituo or Rejuran for summer,

we recommend calmly looking first at what your skin needs most right now.

Finding that answer step by step will be the beginning of making a good choice.

This has been Objet Plastic Surgery.
