Rejuran vs Juvelook in Korea: Comparing Skin Quality Treatments

Two Korean skin quality injectables

Rejuran and Juvelook are both Korean-developed injectables that focus on skin quality rather than shape. They are often mentioned together, and many visitors ask which one to choose. While they share a general goal of healthier-looking skin, they use different ingredients and work in different ways, so the choice depends on what you want to improve and how quickly.

How Rejuran works

Rejuran is based on polynucleotide (PN), a substance derived from purified salmon DNA fragments. It is injected in small amounts across the skin to support the skin's repair environment. It is often discussed for:

Texture. Rough or uneven skin.
Fine lines. Early lines on cheeks and around the eyes.
Resilience. Skin that looks thin, tired or easily irritated.
Elasticity. A subtle improvement in bounce for some people.

Rejuran typically leaves small bumps at injection points that settle within about a day for many people. See our Rejuran page for more detail.

How Juvelook works

Juvelook combines poly-D,L-lactic acid (PDLLA) with hyaluronic acid. The hyaluronic acid gives short-term hydration, while the PDLLA particles stay in the tissue longer and are intended to stimulate collagen production gradually. It is often discussed for:

Pores and texture. Some patients consider it for enlarged pores and uneven surface.
Fine lines and firmness. Through gradual collagen support.
Mild hollowness. Juvelook Volume, a different formulation, is intended for areas needing more support.

Because collagen builds slowly, Juvelook results usually develop over weeks to months. See our Juvelook page.

Key differences at a glance

Main ingredient. Rejuran uses polynucleotides; Juvelook uses PDLLA with hyaluronic acid.
Mechanism. Rejuran focuses on supporting repair; Juvelook focuses on stimulating collagen over time.
Timeline. Both are gradual, but Juvelook is generally described as slower to develop because it relies on collagen formation.
Immediate after-effects. Rejuran commonly leaves small bumps; Juvelook commonly causes swelling for a few days.
Specific risks. Collagen-stimulating products such as Juvelook can occasionally cause persistent nodules. Rejuran involves a fish-derived ingredient, which matters for people with related allergies.
Pricing. Rejuran 2cc has a fixed listed price; Juvelook is quoted after consultation.

Which one might suit you?

There is no single right answer, but these questions can help frame your consultation:

What is your main concern? Texture and resilience may lead to a Rejuran discussion; pores and gradual firmness may lead to a Juvelook discussion.
How much time do you have? Both have downtime measured in days, but swelling from Juvelook may last longer.
Are you planning a series? Both often involve more than one session. Consider whether you can return to Busan or continue at home.
Do you have allergies or medical conditions? Tell the doctor about any fish allergy, autoimmune conditions or pregnancy.

It also helps to think about how you will judge the result. Rejuran is often described in terms of skin feeling healthier or more even, while Juvelook is often discussed in terms of gradual changes in pores or firmness. Taking clear photos in the same light before treatment, and again after a few months, can make subtle changes easier to see. If you are only able to visit Busan once, ask the doctor which option is more likely to give a noticeable change from a single session for your skin, and what follow-up you could arrange at home.

Some patients have both at different times as part of a longer plan. Whether that makes sense is decided by the doctor. Results vary and are not guaranteed.
