Comparisons & Choices — 4.1 Juvelook vs. Rejuran · 4.2 Rejuran HB vs. Juvelook Subdermal Injection

To get straight to the point, Juvelook is a collagen booster* developed by the South Korean company VAIM Global in the early 2020s. By combining PDLLA and hyaluronic acid, it was the first Korean product designed to deliver immediate hydration while simultaneously stimulating long-term collagen production. Today, it is exported to over 70 countries and has become a staple on treatment menus in dermatology and plastic surgery clinics across Korea.

Collagen Booster*: A treatment that stimulates your skin's own natural collagen production. Unlike traditional fillers that fill volume instantly, it gently encourages your skin to generate new collagen over several months.

About VAIM Global

VAIM Global is a specialized medical and aesthetic pharmaceutical company founded in Daejeon, South Korea, in 2014. Starting as a small company focusing on fillers and drug delivery technologies, they early on recognized the potential of PDLLA (poly-D,L-lactic acid), a biodegradable synthetic polymer. This ingredient was originally FDA-approved in the United States to treat facial lipoatrophy in HIV patients, and its safety combined with its collagen-stimulating benefits is already well-proven.

What sets VAIM apart is their creation of a hybrid formulation combining PDLLA with hyaluronic acid (HA)*. While single-ingredient polylactic acid products (such as Sculptra from the US, which contains PLLA) take several months to show effects and deliver no immediate change, Juvelook was thoughtfully formulated with HA so that patients can enjoy visible hydration and a subtle lift right from the start. This allows both practitioners and patients to see and feel the results much sooner, leading to its rapid adoption in clinical practice.

Hyaluronic Acid* (HA): A moisture-binding substance naturally present in our skin. In aesthetic treatments, its molecular weight and viscosity are adjusted to provide immediate hydration and plumping effects.

The Void Juvelook Filled

Around 2020, the Korean aesthetic market had two polarized options. On one hand, there were hyaluronic acid fillers offering immediate but temporary results; on the other hand, there were collagen-stimulating treatments offering long-term but delayed results. Juvelook filled that gap perfectly. It created a beautifully balanced option by offering dewy, refreshed skin right after the procedure, followed by active collagen production kicking in at 1 to 3 months, with results lasting 12 to 24 months.

Another key feature is its excellent compatibility with various treatment delivery methods. Beyond traditional hand injections, it pairs beautifully with advanced devices like the needle-free CureJet, microneedles, and RF devices like Potenza, establishing itself as a versatile skin booster for scars, pores, and overall texture improvement. In one clinical case report, the improvement of tear trough depression was observed just 18 days after Juvelook injection, and its outstanding biocompatibility was confirmed through ultrasound, CT, and MRI imaging.

From South Korea to the World

VAIM Global announced that as of May 2026, cumulative production of Juvelook exceeded 3 million vials. Reaching an additional 1 million vials in just about 8 months—up from 2 million in September 2025—demonstrates how rapidly global demand is rising. Exported to over 70 countries in Europe, Latin America, and Asia, Juvelook made a major entry into the European market through an exclusive distribution partnership with the French medical aesthetics company Laboratoires FILLMED. A comprehensive review of PDLLA use in aesthetic procedures also highlights the entry of Korean PDLLA products into the global market as a highly significant milestone.

What is particularly interesting is that this is the first time a Korean product has secured a significant share in the global collagen booster market—a segment previously dominated by US and European pharmaceutical giants. VAIM carved out its unique space through smart Korean-style R&D: smaller particle sizes, faster onset of action, and seamless compatibility with various combination techniques.

Why the Lineup Keeps Expanding

Juvelook is no longer just a single product, but a complete lineup. Beginning with the classic original Juvelook, the brand has expanded into five tailored options designed for specific areas and goals, including Volume, Skin, Eye (for the delicate eye area), and Glam (for body contouring). By utilizing the same core PDLLA + HA formula and adjusting only the particle size and concentration, they have successfully broadened its applications.

In addition to Juvelook, VAIM also distributes a PDLLA line for global export under the name Lenisna. In international markets, Juvelook Volume is often distributed under the name Lenisna, so you can think of them as sister brands from the same company using the exact same formula. For this series, we will focus primarily on the core Juvelook line.

If you are considering your first aesthetic treatment, it is helpful to know that the single name "Juvelook" encompasses these specialized options. In our next post, we will look into exactly how PDLLA and HA work together under your skin to bring out your natural glow.

Frequently Asked Questions

Q. Is Juvelook the same as a regular filler?

No, they are different. A classic filler uses hyaluronic acid to stay in place and instantly add volume, whereas Juvelook uses PDLLA to stimulate your own natural collagen production, reforming the skin's structure from within. They have different timelines for visible results and overall longevity.

Q. Is PDLLA a safe ingredient?

Yes, PDLLA is a biodegradable synthetic polymer that has been safely used for many years in medical sutures and absorbable medical devices. It originally received US FDA approval to treat facial lipoatrophy in HIV patients, and has since accumulated extensive clinical data for aesthetic use. However, because it requires precise placement, the practitioner's skill and injection depth are very important.

Q. Is Juvelook available outside of Korea?

Yes, it is currently exported to over 70 countries. In Europe, it has been actively expanding since 2024 through an official distribution agreement with a leading French medical aesthetics company. It is quickly becoming a signature product representing K-beauty's collagen booster category.
