Three Things People Who Didn’t See Results from Hongdae Rejuran Missed

Hello. I’m Jo Won-jin, the chief director of Chai Clinic, where I have been treating patients in Hongdae for 10 years.

Director, I got Rejuran three times

and I’ve never seen any resultsㅠㅠ

Even as the weather gets warmer, many people still look for Rejuran because of dull, rough skin.

In fact, quite a few people visit me after getting it three or four times elsewhere

without feeling any change.

So today, under the topic of “Three Things People Who Didn’t See Results from Hongdae Rejuran Missed,”

I’ll organize the three key points for getting the proper results from Hongdae Rejuran.

I’ll explain why the results differ from person to person even with the same procedure,

and how it should be done to get the right effect.

Also, there are many misunderstandings about Rejuran embossing. If you’re curious about embossing and its effects, it would be good to read the post below first.

Why do Rejuran results in Hongdae differ from person to person?

To get straight to the point, the difference in Rejuran results comes down to

• type

• depth

• care

These three factors.

Not long ago, someone came to me saying they had the procedure three times at another clinic

but didn’t feel anything had changed.

After hearing their story, I found that they were concerned about pores and scars,

but what they had actually received was Rejuran for hydration.

The very first step was wrong.

Cases like this happen more often than you might think.

Rejuran is not just one product; there are several types,

and even with the same product, the effect changes depending on how deep it is injected.

On top of that, the result is determined by how you spend the days after the procedure.

Let’s go through the three points one by one.

Key 1. Choose the right Rejuran type for your skin concerns

The first key point is choosing the right type.

Among people looking for Rejuran in Hongdae,

many think “Rejuran is just one type,” but

in reality, there are several types.

Features and recommended concerns by Rejuran type

Type	Features	Recommended areas, concerns
Rejuran Healer	100% PN ingredient	Overall skin barrier strengthening, improved elasticity
Rejuran HB	PN + hyaluronic acid compound formula	Improved hydration and elasticity at the same time
Rejuran I	Lower concentration and softer particles	Fine lines in thin, sensitive areas such as around the eyes
Rejuran S	High viscosity, stays deeper for longer	Scars, acne marks, large pores

The principle is simple.

A smaller, more fluid formulation spreads well in thin skin.

A larger, stickier formulation stays deeper for longer

and produces a stronger regenerative effect.

So there are different procedures that suit different skin concerns.

• If your skin texture is rough and pores are a concern: Rejuran Healer, which has strong regenerative power

• If you want hydration and elasticity at the same time: Rejuran HB, which includes hyaluronic acid

• If you have fine lines in areas with thin skin, such as around the eyes: Rejuran I, with smaller, softer particles

• For deep indentations or acne scars: Rejuran S with strong regenerative power

What happens if you increase the number of sessions without knowing this difference?

If you are concerned about deep acne scars but keep getting a product mixed with hyaluronic acid

no matter how many times you receive it, it will be difficult to see a satisfying result.

The same cost and the same number of sessions can lead to completely different results depending on what is used and where.

That is why, before getting Rejuran in Hongdae,

you should make sure your skin is accurately diagnosed and that the clinic recommends the right type for it.

Key 2. Injection depth that determines the effect

The second key point is to inject evenly at the correct depth within the dermis.

When receiving Rejuran’s PN ingredient for pore or scar treatment,

the cells that produce collagen must be stimulated for the effect to appear.

These cells are not in the skin’s outer layer (epidermis),

but in the deeper layer of the skin, the subdermal dermis.

Simply put, rather than being injected superficially, it needs to be injected accurately into the subdermal dermis for the effect to show properly.

What happens when the depth is off If injected too shallow:

It can help improve dryness. However, it is not suitable for improving pores or deep indentations.

If injected too deep:

The medication passes beyond the cell layer that should be stimulated

and ends up near the fat layer.

Then the collagen response itself becomes weaker.

Dermal thickness varies by area The cheeks are thick, while under the eyes, around the mouth, and the neck are very thin.

If the same depth is used regardless of the area,

results may be less noticeable in thicker areas of the skin.

That is why, even though we have equipment such as Dermashine that delivers injections at a consistent rate at our clinic,

I usually recommend getting it by manual injection whenever possible.

In the end, it is important to consider the different skin thicknesses of each patient by area,

and to adjust the depth accordingly while injecting evenly within the dermis.

The under-eye hollow and nasolabial fold areas in the photo above are also injected into the lower dermis to stimulate collagen production more strongly.

Key 3. Post-procedure care that makes use of the collagen golden time

The third key point is how you spend the recovery period after the procedure.

Hongdae Rejuran is not a treatment that ends with the procedure itself.

You should view it as a treatment that includes the skin’s regeneration process after the procedure.

From immediately after the procedure to one week later, it is a soothing and recovery period,

and from 4 weeks to 12 weeks, new collagen begins to regenerate and settle in.

So whether collagen production proceeds well is most strongly affected during the first week after the procedure.

Why post-procedure care matters After the procedure, we also provide care that helps calm the skin and support absorption.

This includes a soothing mask to reduce skin heat,

LDM device care to support regeneration, and finishing with ointment.

Through this, we help quickly calm irritation and support stable recovery.

If this step is not sufficient, bruising and swelling can last longer, and recovery takes more time.

Lifestyle care you should handle yourself

Saunas, jjimjilbangs, and other environments that raise skin temperature, drinking alcohol, and exposure to ultraviolet rays can prolong bruising and swelling, so it is best to avoid them as much as possible.

Moisturizing and sun protection should also be followed carefully.

Even if you consistently keep up with just these two things, they can greatly help maintain the collagen created by the procedure in a stable way.

In the end, Rejuran delivers maximum effect not only through the procedure itself,

but when post-procedure care is also carried out together.

Frequently Asked Questions (FAQ)

Q. How many sessions of Rejuran are usually needed to see results?

A. Usually, we say around 3 sessions.

However, what matters more than the number of sessions is the right type for your concern and the correct injection depth.

Rather than receiving the wrong type 4 or 5 times,

it is more effective to receive the right type properly 1 or 2 times.

Q. Does it hurt so much that you need sedation anesthesia?

A. Even people who tolerate pain well can find Rejuran painful.

That is why, in our clinic, we use nano needles thinner than standard Rejuran needles

and use laughing gas (AirNox) to dull sensation itself so that patients can receive the procedure as comfortably as possible.

Using these two methods makes the procedure much easier for most people compared with receiving it without them.

Hongdae Rejuran, key summary for getting proper results

• Type: Even if it is the same Rejuran, the type is different. You need to choose the one that fits your concern: wrinkles, scars, pores, or hydration.

• Depth: Not all dermis is the same. It must be placed at the exact depth where the cells that produce collagen are gathered.

• Care: The procedure is not the end, it is the beginning. One week of post-procedure care accounts for half of the result.

Only when all three of these factors align can you truly see results.

When deciding on Rejuran, do not look only at the number of sessions or the cost,

but check whether the clinic chooses the right type for your concern,

and whether it also takes care of the depth and post-procedure care.

Thank you. This was Jo Won-jin.
