Juvelook vs. Rejuran: Choosing According to Your Skin Concerns
When rough skin texture or fine lines become a concern, people often look up these two injectable treatments together.
Here, we explain how your current skin concerns and the changes you hope to see can guide your choice, beyond the ingredient names.

Key Points
Juvelook and Rejuran have different ingredients and research evidence.
First distinguish texture concerns from depressed areas.
Redness, swelling, and bruising can occur after injections.
Check the injection site and treatment purpose, as well as the product name.
Hello from DATENA Clinic.
Both names are often presented as injections for improving skin condition, so it is easy to assume they are the same treatment.
However, skin that looks dry and a localized depression require different assessments.
Although both treatments involve injections, they do not necessarily address the same skin problem.
In particular, grouping red marks together with depressed scars can lead to an unsuitable product choice from the start.
Instead of memorizing the differences between the two products, this article explains which questions to ask first.
1. Why skin texture and depressed marks need separate assessment
It is important to distinguish whether your main concern is fine lines and dry texture or a shallow depression in a particular area.
Post-inflammatory color changes and visible pores can also make the surface look uneven, so both visual examination and assessment by touch are needed.
For example, a mark that only changes skin color leaves the surface level unchanged, whereas a depressed scar can cast a shadow depending on the direction of the light.
The first step is to set separate goals for skin texture and localized depressions.
When the causes differ, the changes you notice may also differ, even with the same product.
2. Ingredients and formulations of Juvelook and Rejuran
Juvelook is a product family combining PDLLA and hyaluronic acid, while Rejuran is a product family containing polynucleotides.
Formulations and intended uses can vary within each family. The name alone does not mean that products are injected at the same depth or in the same amount.
During consultation, clarify whether the product is Juvelook or Juvelook Volume, and which Rejuran formulation is being considered.
Even within the same product family, a different formulation may mean different treatment areas and risks that need explanation.
Studies also differ in participants, treatment sites, and assessment times, making it difficult to conclude that one product is better in every respect.
Category | Juvelook family | Rejuran family |
|---|---|---|
Main ingredients | PDLLA and hyaluronic acid | Polynucleotides |
Consultation focus | Type of unevenness and injection plan | Texture concerns and exact product |
Reactions to discuss | Bruising, swelling, and possible nodules | Bruising, swelling, and injection reactions |
3. Assessing dry, rough skin texture
Dryness and fine lines should be assessed together with hydration, possible dermatitis, and facial movement.
Rejuran studies have assessed certain measures of skin condition, but some studies are small, and findings vary with the comparison used.
Even when dryness is pronounced, accompanying dermatitis may mean inflammation needs treatment before injections are considered.
It also helps to check whether the skin texture measures used in a study reflect the hydration or radiance you are hoping for.
A product name alone therefore cannot predict how much your skin texture will change.
4. Examining the depth and edges of depressed scars
If a depressed acne scar is tethered beneath the skin, injections alone may be insufficient.
Juvelook studies have also involved specific sites and groups of participants, so their results cannot be applied directly to every scar type.
Whether a depression changes when the skin is stretched and whether its edges are sharply defined can help with scar assessment.
When color changes and depressions coexist, it is more accurate to consider these as separate concerns rather than explain both through one product.
Depending on scar depth, edges, and active acne, another treatment may take priority.
5. Distinguishing swelling from nodules after injections
Both treatments can cause needle-related pain, redness, swelling, and bruising.
Palpable nodules can occur rarely with the Juvelook family, and worsening pain or warmth needs assessment.
Early swelling may change over several days, while a firm lump that appears later needs a different evaluation.
Increasing warmth and tenderness in the same area, or spreading redness, should not automatically be regarded as normal recovery.
Even if the skin looks bumpy immediately afterward, follow the aftercare instructions rather than pressing or massaging the area on your own.
6. Three things to check before choosing a product
Useful questions include whether the concern is texture or a depression, exactly which product and injection site are planned, and which reactions to monitor afterward.
At DATENA Clinic, we first consider whether the current skin condition and treatment goal match, rather than starting with a product name.
If you have recently had acne treatment or a laser procedure, share when it took place.
Having several procedures close together can sometimes make it difficult to identify which treatment caused a particular reaction.
Results vary between individuals, so discuss the expected range of changes and the limitations before treatment.
Although Juvelook and Rejuran are often mentioned together, they do not treat the same problem in the same way.
Understanding their differences involves more than comparing ingredient lists.
Defining each specific change you want in your skin makes the consultation more useful.
Identifying what bothers you most about your skin can help narrow the options.
