Introduction
“I’m interested in a skin booster injection, but I don’t know the difference between Rejuran and Juvelook” is a question we often hear.
Both are injectable treatments chosen for firmness, texture, pores, and fine lines, but they differ in ingredients, the concerns they address best, and the areas they suit.
This article explains the differences in a way that is easy to understand even if you are considering these treatments for the first time.
What is Rejuran?
Rejuran is an injectable preparation whose main ingredient is polynucleotides (PN).
It is often chosen by people concerned about fine lines around the eyes, loss of firmness, and uneven texture in areas with thin skin.
At our clinic, the doctor assesses suitability by area and concern, such as around the eyes or the full face.
What is Juvelook?
Juvelook is a preparation that contains poly-D,L-lactic acid (PDLLA) and non-crosslinked hyaluronic acid.
It is often chosen by people who want to improve pores, acne scars, skin unevenness, and loss of firmness.
Depending on your skin condition and the treatment area, manual injection or water-light injection may be considered.
Comparing the two
| Item | Rejuran | Juvelook |
|---|---|---|
| Main ingredients | PN (polynucleotides) | PDLLA, non-crosslinked hyaluronic acid |
| Common concerns | Fine lines around the eyes, firmness, texture | Pores, acne scars, skin unevenness |
| Typical areas | Around the eyes, full face | Cheeks, pore-prone areas, full face |
| Treatment interval | Multiple sessions depending on condition | Multiple sessions depending on condition |
| Downtime | Redness, swelling, bruising, wheals, etc. | Redness, swelling, bruising, small lumps, etc. |
Which one should you choose?
If fine lines around the eyes or firmness of thin skin are your main concerns, Rejuran can be a candidate.
If pores, acne scars, or the texture of your cheeks are your main concerns, Juvelook can be a candidate.
In practice, the most suitable treatment depends on your skin type, skin thickness, medical history, and how much downtime is acceptable.
It is less about which one is “better” and more about which concern, which area, and which method.
How is this different from water-light injection?
Water-light injection is an injection method, not the name of a preparation.
It can be used as a way to deliver preparations such as Rejuran or Juvelook finely into the shallow layers of the skin.
Even with the same preparation, manual injection and water-light injection differ in depth, density, and the concerns they suit.
Risks and side effects
Both Rejuran and Juvelook are self-pay treatments (not covered by public health insurance) in Japan.
After treatment, redness, swelling, pain, bruising, wheals, itching, small lumps, and asymmetry may occur.
How symptoms appear and how long they last vary from person to person.
Summary
Rejuran and Juvelook are both injectable treatments considered for improving skin quality, but they suit different concerns and areas.
Rejuran tends to be a candidate for firmness and fine lines around the eyes, while Juvelook tends to be a candidate for pores and acne scars.
At VIVIAGE ZONNE CLINIC, we examine your skin first and then propose a suitable option from Rejuran, Juvelook, water-light injection, Dermapen, and more.
