People looking into Rejuran often do so when they feel that their skin condition is no longer what it used to be.
They may repeatedly notice changes such as makeup not applying smoothly, rougher skin texture, and more visible fine lines.
However, looking through reviews can also raise some questions.
“Are there certain types of skin that respond better to Rejuran?”
“What if I do not see any results after treatment?”
“Would Juvelook or another skin booster be a better fit for me?”
Rather than being a treatment that resolves all skin concerns at once, Rejuran is a skin booster whose level of satisfaction may vary depending on the condition of the skin.
Today, for those considering the effects of Rejuran, we will summarize the skin conditions to check before treatment, when it may be suitable, and when its effects may feel insufficient.
- Rejuran is a skin booster focused on restoring skin condition

Rejuran is a skin booster that involves injecting PN, a DNA component extracted from salmon, into the skin to help restore its condition.
Because it contains a salmon-derived component similar to human DNA, it is characterized by a low likelihood of side effects and a high level of safety.
It is often considered when the skin feels thinner and drier, fine lines are visible, dryness is present, and skin texture has deteriorated.
In other words, the effects of Rejuran are closer to helping restore the skin from within so that it becomes somewhat healthier and firmer.
Therefore, it is important to distinguish from the beginning whether the desired effect is skin volume, restored elasticity, or improved pores.
- Rejuran may be considered for dry, thin skin

Rejuran is often considered when the skin is thin and sensitive, or when dryness makes fine lines stand out more clearly.
It may be a good fit when fine lines have increased in thin-skinned areas such as around the eyes, around the mouth, or on the cheeks, or when makeup settles unevenly and the skin texture has become rough.
Rejuran may also be considered when the skin has become sensitive and reddens easily, or when dryness and tightness recur depending on its condition.
It may also be suitable for those who want to smooth and refine their skin texture and restore the condition of thin skin, rather than strongly reducing pore size.
Conversely, if the main concerns are deep depressions, clearly insufficient volume, or significant sagging, satisfaction may be low with Rejuran alone, so it should be distinguished from fillers or lifting treatments.
- In these cases, the effects may feel insufficient

When people feel that Rejuran has had no effect, it is often because the treatment did not match the direction of their expectations rather than because of the treatment itself.
When there is substantial volume loss, such as deep nasolabial folds or hollowness under the eyes, fillers may be more suitable.
When lifting is needed for sagging along the jawline or cheeks, the changes achievable with Rejuran alone may be limited.
If the main concerns are enlarged pores, depressed scars, or reduced skin density, it may be necessary to compare Rejuran with Juvelook or laser treatments.
Because Rejuran is a treatment focused on skin condition and fine-line improvement, it is important to first identify which layer or aspect of the skin is causing the concern.
- Rejuran and Juvelook have different purposes

Although Rejuran and Juvelook are both categorized as skin boosters, the criteria for choosing between them are different.
Rejuran is often considered when the skin needs recovery due to dryness, sensitivity, fine lines, or deteriorated skin texture.
Juvelook is more often mentioned for concerns requiring collagen stimulation, such as enlarged pores, scars, reduced elasticity, or improving skin density.
Rather than one being better than the other, the deciding factor is whether the skin currently needs recovery or requires structural support for elasticity.
Therefore, before consulting about Rejuran, it is better to organize the priorities of your skin concerns instead of simply choosing a popular skin booster.
- Pain and raised bumps should also be understood in advance

Because Rejuran is injected directly into the skin, it may cause pain, swelling, redness, or bruising.
Small raised bumps may appear after treatment, and in most cases they tend to subside over time.
However, the reaction may appear more noticeable if the skin is thin or sensitive.
If you have an important event scheduled, it is better to plan the treatment with a few days of extra time beforehand.
To maximize the effects of Rejuran, the injection depth, treatment intervals, and dosage for each area must also be appropriately adjusted, rather than focusing only on the ingredient itself.
In summary
Rejuran is a skin booster injected directly into the skin, so it should not be viewed simply as a procedure that puts a product into the skin.
Even with the same Rejuran treatment, the injection depth and intervals should vary according to skin thickness, degree of dryness, location of fine lines, and sensitivity.
In particular, areas with thin skin, such as around the eyes or mouth, may show swelling or raised bumps more noticeably even with small differences, so careful assessment is needed.
If you are considering Rejuran, rather than deciding based only on reviews, it is advisable to have a plastic surgery specialist directly assess your current skin condition and discuss the injection areas and treatment plan that suit your skin.
