Hello! This is Seye clinic, where we embrace all facets of beauty.
"Doctor, what’s really the difference between Rejuran, Re2O, and Juvelook?"
We often hear how difficult it is to find the most suitable skin booster, given the overwhelming number of procedures and positive advertisements. Today, we would like to scientifically clarify the real differences and ideal candidates for Elravie Re2O, Rejuran HB, and Juvelook Skin.
A skin booster is an aesthetic treatment involving the injection of ingredients that help promote regeneration, hydration, and collagen production into the dermis. Each skin booster has its own unique effects and mechanisms of action.
Today, I'll compare and explain the three most representative skin boosters.
Elravie Re2O uses a concentrated dose of acellular homograft dermis (ECM) derived from human dermis. While traditional skin boosters focus on "stimulation," this product adds a structural scaffold to target density and elasticity improvements. Rejuran HB combines PN (from salmon DNA) with hyaluronic acid to provide regeneration signals and hydration simultaneously. Juvelook Skin delivers a blend of PDLLA particles and HA, where HA provides immediate hydration and PDLLA gradually induces collagen synthesis for smoother texture and pore improvement.

Each treatment has a clear target focus.
Elravie Re2O is recommended for those struggling with decreased skin density or elasticity, fine lines, enlarged pores, or pigmentation concerns. Rejuran HB is suitable for delicate, dry skin that requires both regeneration and hydration, and is particularly good for those just beginning to show signs of aging, as it is hydrating and relatively low in pain. Juvelook Skin is best for those seeking natural results and improvements in skin texture, pores, scars, or hollowed areas.
Product Name | Main Ingredients/Effects | Target Concerns | Recommended For |
|---|---|---|---|
Elravie Re2O | ECM (collagen, elastin, etc.) | Loss of density, fine lines, pores, pigmentation | Fundamental structural restoration, for those unsatisfied with existing boosters |
Rejuran HB | PN + HA | Thin, dry, need for regeneration + hydration | Hydration, lower pain, younger age groups |
Juvelook Skin | PDLLA + HA | Pores, scars, texture, hollowness | Texture/pore/scar improvement, natural collagen induction |
In short, if your main concern is "fundamental skin density and elasticity," Elravie Re2O is suitable; for thinning and dryness, Rejuran HB; and for texture, pores, or scars, Juvelook Skin is optimal.

All three are performed after applying numbing cream, though the procedure times vary. Elravie Re2O typically uses one vial (5cc) of high-concentration product per session, with almost no downtime and gradual improvements in regeneration and density. Rejuran HB is quickly hydrating with relatively little pain and tends to last longer. Juvelook Skin requires a longer procedure time and produces gradual results, but return to daily activities is generally comfortable.
Product Name | Anesthesia/Pain | Procedure Time | Downtime | Results & Duration | Price Range |
|---|---|---|---|---|---|
Elravie Re2O | Cream, minimal | Short | Almost none | Gradual improvement in density & elasticity, structural change | Upper-mid |
Rejuran HB | Lidocaine, minimal | Short | 1–2 days | Quick hydration, relatively long-lasting | Lower-mid |
Juvelook Skin | Cream, minimal | Relatively long | None | Gradual improvement in pores, texture, elasticity | Mid |
Quick hydration and low pain are strengths of Rejuran HB; structural and density enhancement are the strengths of Elravie Re2O; while Juvelook Skin is characterized by improving skin texture, scars, and promoting natural results.
Q. What’s the difference between Rejuran Healer and Rejuran HB?
A. Rejuran Healer focuses on PN as the sole main ingredient, whereas Rejuran HB adds hyaluronic acid for enhanced hydration and pain relief.
Q. Is the "5cc one vial" standard for Elravie Re2O important?
A. Clinically, a single session using one vial at full concentration has shown both good efficacy and safety. At our clinic, we strictly adhere to this principle without dilution to provide real results.
Q. How does Juvelook Skin differ from a Filler?
A. Unlike simple volumizing Filler, Juvelook Skin is a booster that improves skin texture and pores through collagen stimulation for a more natural result.
Q. Is it possible to combine or alternate different procedures?
A. Since each skin booster has different effects and roles, combining them appropriately under a medical professional's judgment—tailored to the skin's condition—can create excellent synergy. It is possible to alternate or combine treatments in steps depending on your skin’s condition. We recommend individualized treatment planning following a professional diagnosis.
In our consultations, we often meet clients who say, “I tried it just because of the ads, but I saw no real change.” At our clinic, we use the EVE LAB system and 3D facial analysis to assess skin thickness, fat distribution, and pore patterns with data-driven precision. As an officially certified "Key Clinic" for Elravie Re2O, we adhere strictly to the genuine 5cc one vial protocol without any unnecessary dilution, ensuring safety. One-on-one consultations and university hospital-grade sleep monitoring help minimize risks of over-stimulation or side effects, providing truly personalized skin booster solutions.

Choosing the right skin booster tailored to your unique concerns is crucial to achieving noticeable results. For any questions, please visit us for consultation and diagnosis.
