Confused about the differences between Hongdae Skin Boosters: Rejuran, Juvelook, and Water Glow Injections?

April 8, 2026

Hello!

I am Dr. Dong-young Kim, Director of Cleor Clinic Hongdae Branch.

"What is the difference between Rejuran, Exosome, and Mulgwang (Water Glow) Injections?"

Since all three are administered via injection and are said to improve the skin,

many people find it difficult to choose between them.

In fact, it's not just the names that are different;

the ingredients injected into the skin and the expected results vary significantly.

To put it simply, while the destination may seem similar, the methods of getting there are completely different.

Although they share the same goal of "skin improvement,"

the changes you can expect depend on the approach taken.

For those considering skin boosters in Hongdae,

today I will summarize the differences between these representative treatments.

Why does the skin change?

Skin changes that occur with age are not just about wrinkles.

Collagen and elastic fibers in the dermis decrease,

and as the rate of cell regeneration slows down, the overall condition of the skin gradually declines.

When these changes accumulate, they lead to the following concerns:

  • Pores become more visible and skin texture becomes rough

  • A sagging sensation as elasticity in the facial line decreases

  • Increase in fine lines and decrease in skin thickness

  • A lifeless and dull complexion

To improve these changes from within the skin,

skin booster treatments are utilized.

How do Rejuran, Juvelook, and Mulgwang Injections differ?

  • Rejuran Healer

Rejuran involves injecting PDRN/PN components extracted from salmon

directly into the dermal layer.

👉 It can be understood as creating an environment

where damaged skin can recover and regenerateon its own.

It is well-suited for skin that is sensitive to external stimuli or flushes easily,

as well as for those concerned about skin texture and pores.

Rather than a dramatic change after a single session,

it is a treatment where the skin's natural strength increases with more sessions,

leading to higher satisfaction with consistent treatment.

  • Juvelook

Juvelook is a combination of PDLLA (Poly-D,L-Lactic Acid) and Hyaluronic Acid,

which induces collagen production within the dermal layer.

Effects gradually appear 4 to 6 weeks after the procedure,

and are most noticeable at the 2 to 3-month mark.

Rather than immediate changes, it is a treatment where

the skin structure itself improves over time,

👉 making it suitable for those whose primary concerns

are loss of elasticity, fine lines, or decreased skin volume.A key feature is that the duration of the effect is relatively long.

Mulgwang (Water Glow) Injection

  • A skin booster with Hyaluronic Acid as the main ingredient,

it fills the skin with moisture and provides an immediate glow

while improving skin texture.

While Rejuran and Juvelook focus on skin regeneration and structural improvement,

👉

Mulgwang Injections are closer to skin hydration and immediate condition recovery.At Cleor Clinic Hongdae Branch,we offer various products such as LILIID M, Juvederm SKINVIVE, and Belotero Revive,

and we tailor the treatment with the most suitable product

based on individual skin conditions and concerns.Recovery periods vary by treatment

After Rejuran, an 'embossing' effect where injection marks appear raised

may occur,

and partial bruising may also happen.

For Juvelook, swelling and embossing usually subside within a few days,

but since they may persist for a certain period depending on the individual,

it is recommended to allow enough time before important schedules.

Mulgwang Injections have the shortest downtime among the three;

temporary swelling or redness may occur,

but most subside quickly on the same day or the following day.

but the decision to combine should be made carefully based on skin condition.

  • Frequently Asked Questions

  • Q. Which treatment is the best?

A. No single treatment is unconditionally superior. The most suitable treatment depends on your current skin condition and desired results.

Q. How many sessions of Rejuran are required?

A. Generally, a minimum of 3 sessions at 2-3 week intervals is standard,

and many people maintain the results with sessions every 3-6 months thereafter.

Q. How many sessions of Juvelook are required?

A. 3 sessions at 3-4 week intervals are often recommended,

and the effect typically lasts about 6 to 12 months based on 3 sessions.

Q. Can I go to work the day after the procedure?

A. It is mostly possible, but embossing, bruising, or swelling may remain depending on the individual.

Q. Can I receive two or more treatments on the same day?

A. It is possible in some cases, but depending on the skin condition,

it may be more appropriate to proceed in stages.

Rejuran, Juvelook, and Mulgwang Injections are all popular skin boosters in Hongdae,

but their mechanisms of action and suitable skin conditions are distinctly different.
