Skin Boosters for Hot Summer Days: Rejuran & Juvelook for Pores and Redness

Hello, I’m Dr. Kim Yeon-Jin, Medical Director of UH CELL Gangnam (formerly Dr. Petit Clinic Gangnam). 🙂
Today, I’d like to introduce one of the most frequently requested skin booster combinations at our Gangnam clinic.

What are the most common skin concerns during the summer?

During consultations, the two concerns I hear about most often are redness and enlarged pores.

These concerns tend to become even more noticeable in environments like Seoul, where the skin is exposed to intense sunlight and heat.

The key to addressing both of these concerns ultimately comes down to skin recovery and regeneration. That’s why, these days, skin boosters often provide higher patient satisfaction than lifting treatments alone.

In fact, skin boosters have become one of the biggest trends in Korean aesthetic medicine for achieving natural-looking skin improvement.

The combination I’d like to talk about today is Rejuran + Juvelook, one of the treatments we’ve been receiving a lot of inquiries about recently.
These two treatments complement each other, and we’ve seen many cases with excellent results.

So, why is this combination so effective for redness and enlarged pores?

Let’s start with Rejuran.

The key ingredient in Rejuran is PN (polynucleotide), which consists of DNA fragments derived from salmon. Because it is highly compatible with human DNA, it is particularly effective in supporting skin repair and regeneration.

This ingredient has consistently demonstrated both its safety and effectiveness in Korea.

There are many causes of facial redness, but in most cases it is associated with a compromised skin barrier along with inflammation.

In these situations, what the skin needs is more than just soothing—it needs repair and regeneration. This is where Rejuran plays an important role.

This is especially true for sun-induced skin damage during the summer. When it comes to sunburn, the speed of skin recovery is key, and we’ve seen many cases in Gangnam where patients experienced a faster recovery with this approach.

In fact, at our clinic, we’ve had several cases where we were impressed by how quickly the skin recovered after using Rejuran for sunburn-related skin damage.

Even in older patients, the recovery has often been faster than expected.

So, what role does Juvelook play?

Juvelook is a skin booster that is particularly effective for improving enlarged pores and dry skin.

Its main ingredient stimulates collagen production, helping to strengthen the dermis and improve the appearance of enlarged pores.

It also contains hyaluronic acid, so many patients notice an immediate boost in skin hydration right after the treatment.

This instant hydration is one of the factors that contributes to the high level of patient satisfaction with Korean aesthetic treatments.

As a result, Juvelook helps improve overall skin quality by strengthening the skin’s structure, minimizing the appearance of pores, and restoring hydration for a healthier-looking complexion.

So, why do these two treatments work so well together?

When Rejuran helps restore the skin barrier first, your skin becomes better able to retain the hydration provided by Juvelook.

In other words:

• Redness → Rejuran
• Enlarged pores → Juvelook
• Long-lasting results → The synergistic effect of combining both treatments

Together, they provide a more comprehensive and structural improvement to the skin.

This combination has recently become one of the most popular treatment options in Seoul due to its high patient satisfaction.

How many treatment sessions are recommended?

We typically recommend a series of three sessions.

Enlarged pores improve most noticeably when enough new collagen has been produced, which is why consistent, repeated treatments are more effective than a single session.

Skin regeneration also relies on cumulative results, so regular maintenance is essential for achieving the best outcome.
This gradual, long-term approach is widely recommended in Korean aesthetic medicine to maximize both skin quality and treatment longevity.

Now, let’s talk about the question everyone asks: Does it hurt?

To be honest, yes—it can be a little painful or uncomfortable. 😊
That said, the treatment itself doesn’t take very long, so most patients find the discomfort quite manageable.

At our clinic, we take pain management seriously by carefully applying a topical numbing cream and allowing sufficient wrapping time to ensure optimal absorption before the procedure. This attention to detail is considered an important part of high-quality aesthetic treatments in Korea.

If you’re particularly concerned about discomfort, we often recommend Rejuran HB.

Rejuran HB contains both hyaluronic acid and lidocaine, making the treatment feel significantly more comfortable than standard Rejuran for most patients.

Another advantage is that if you undergo Rejuran HB first, subsequent Juvelook treatments are often more comfortable as well, making it an excellent option for patients who are sensitive to pain.

So, how do you choose the right clinic?

This is a point I’ve been emphasizing ever since I was practicing at Dr. Petit Clinic Gangnam.

1. Choose a clinic that uses authentic products and the correct dosage.
   It’s important to verify that the product is opened in front of you before the treatment begins.
   This is considered a key standard of safe and transparent aesthetic practice in Korea.
   
2. Choose a clinic with extensive aesthetic design experience.
   Every area of the face has different characteristics and needs.
   For example, the butterfly zone (across the nose and cheeks) is often more affected by redness, so Rejuran may be the better option for that area. On the other hand, the area beneath the chin may benefit more from Juvelook if enlarged pores or acne scars are the primary concern.

Each area should be approached differently.

This customized treatment plan is also considered an important factor in Seoul.

The combination of Rejuran and Juvelook is not just a treatment—it is a way to improve the skin’s underlying structure.

This can be an effective approach, especially for those who are concerned about both redness and enlarged pores. Recently, these combination treatments have continued to gain attention in Korean aesthetic trends.
