“Is it okay to receive Rejuran and Juvelook

on the same day?”

Recently, more and more people have been interested in combinations of skin boosters.

As a result, many people have been asking about the synergy of combining the well-known treatments Rejuran and Juvelook.

Since the characteristics and particle sizes of their respective ingredients differ, you may be wondering how the treatments are performed and whether they would be suitable for you.

Today, based on frequently asked questions, we will go through these points one by one.

Seokchon Gobun Station Dermatology Clinic,

Curious About the Combination of Rejuran and Juvelook?

  • Can they be administered together on the same day?

  • What are the effective treatment methods and number of sessions?

  • Pain and downtime

Seokchon Gobun Station Dermatology Clinic (Department: Dermatology) Can They Be Administered Together on the Same Day?

To begin with the conclusion, PN, which helps create a regenerative environment within the skin, and PDLLA, which stimulates collagen production, have different mechanisms of action, so they can be administered together on the same day.

Rejuran’s salmon-derived PN ingredient is characterized by delivering active substances to the dermal layer, helping to ease damaged tissue and improve the skin’s moisture-retention capacity.

In contrast, the PDLLA ingredient in Juvelook gradually breaks down in the body and induces collagen production, helping to supplement the skin’s internal structural density and elasticity.

Because they have complementary goals, applying them together may allow for broader improvement of the skin environment.

However, even when the same combination is used, responses may differ depending on factors such as sebum production, skin thickness, and the condition of the dermal layer.

Since individuals differ in the amount of ingredients their skin can accommodate, applying the same injection ratio to everyone should be avoided.

We recommend carefully adjusting the amount administered and the injection area for the day without overdoing it, taking each person’s skin thickness into account.

Seokchon Gobun Station Dermatology Clinic (Department: Dermatology) What Are the Effective Treatment Methods and Number of Sessions?

When performing a combination treatment, it is advisable to proceed sequentially, taking into account the target depth of the dermal layer where the ingredients are injected and the characteristics of the particles.

In general, PDLLA is applied to the lower dermal layer to help form the skin’s structural density.

Afterward, PN is injected into the upper dermal layer to supplement the regenerative environment and moisture retention.

Applying the ingredients by separating the layers in this way may help each ingredient perform its intended role.

However, this schedule and number of sessions do not apply equally to all skin types, and the injection layer may also vary depending on the degree of aging and the condition of the skin.

Therefore, during the actual injection process, it is important to carefully adjust the depth and amount for each layer while checking the condition of the skin and the tissue response.

Typically, this type of combination treatment is often performed about three times at four-week intervals to improve skin texture and structural density.

Ultimately, rather than relying only on a set number of sessions, it is advisable to create a plan suited to the individual’s skin condition and goals based on a thorough consultation.

Seokchon Gobun Station Dermatology Clinic (Department: Dermatology) What Is the Difference in Pain and Downtime?

The two ingredients differ in viscosity and particle characteristics, so there may also be differences in the stimulation felt during injection and in the recovery process.

PN is relatively viscous, so temporary soreness or raised bumps may last for one to two days after injection.

In contrast, PDLLA generally causes less pressure during injection, but mild redness or bruising may appear for several days afterward.

Both ingredients are reported to begin producing tissue responses around two weeks after injection, with changes in skin texture appearing around the two-month mark.

Pain and recovery usually last about one day, but there can be significant individual variation, and marks may remain longer in people with sensitive skin.

Therefore, rather than referring only to reviews or average recovery timelines, please consider your current skin condition and the changes you hope to achieve when making a plan.

Today, we looked at the characteristics and points to keep in mind regarding the combination of Rejuran and Juvelook at a Seokchon Gobun Station dermatology clinic.

Because the two ingredients work in different ways, the timing and nature of changes and responses may vary depending on skin condition, degree of aging, and the body’s metabolic environment.

Rather than making a decision based simply on someone else’s experience, we recommend proceeding after thoroughly assessing your current skin condition and establishing a plan for the appropriate scope of treatment.
