Rejuran Eye is a specialized skin booster designed for the delicate, thin, and frequently moving skin around the eyes. It contains PN (Polynucleotide), which is injected into the skin to promote skin regeneration and improve elasticity.

The skin around the eyes is thinner and contains fewer sebaceous glands than other areas of the face. As a result, dryness, fine lines, and loss of elasticity tend to become noticeable relatively early.

Rather than creating significant volume in hollow under-eye areas, Rejuran Eye focuses on improving the quality of thin, weakened, and finely wrinkled skin around the eyes.

Fine, crepey wrinkles under the eyes → Rejuran Eye

Thin skin and reduced elasticity around the eyes → Rejuran Eye

Under-eye wrinkles caused by dryness → Rejuran Eye

Expression lines that appear when smiling → Botox

Deep under-eye hollows that create shadows → Volume restoration treatments

Pigmentation-related or vascular dark circles → Targeted pigmentation or vascular treatments

Therefore, when considering Rejuran Eye, it is important to determine whether the main concern is thinning skin and reduced elasticity rather than simply the presence of dark circles.

What Is Rejuran Eye?

Rejuran Eye is a specialized skin booster that delivers PN directly into the delicate skin around the eyes to promote skin regeneration and improve elasticity.

The eye area is one of the first areas of the face to show visible signs of aging.

Because the skin is thin and constantly moves when blinking or smiling, even a slight reduction in elasticity can lead to the development of fine lines.

When the skin also lacks moisture, the under-eye area may develop a crepey texture, making wrinkles more noticeable. Foundation or concealer may also settle into these fine lines, emphasizing their appearance.

Rejuran Eye delivers PN into the skin to support its regenerative environment, encourage collagen production, and help restore elasticity.

In other words, the goal is not to add significant volume beneath the eyes but to improve the strength, firmness, and overall quality of the delicate skin itself.

What Are the Benefits of Rejuran Eye?

Rejuran Eye is used to address signs of aging related to the skin itself, including fine lines, dryness, thinning skin, and reduced elasticity around the eyes.

Aging around the eyes is not simply about the appearance of individual wrinkles.

As the skin becomes thinner and loses its ability to retain moisture, the under-eye area may appear dry and rough. Reduced elasticity can also cause multiple fine lines to develop.

Rejuran Eye aims to stimulate the skin's regenerative response, helping improve skin density and elasticity over time.

It may be particularly beneficial for individuals experiencing:

Increasing fine lines and crepey wrinkles beneath the eyes
Thin, loose, or weakened skin around the eyes

Dryness and roughness in the under-eye area

Wrinkles that become more noticeable when applying makeup

Uneven or rough skin texture around the eyes
Overall loss of firmness and elasticity around the eyes

The key concept behind Rejuran Eye is improving the condition of the skin where wrinkles develop, rather than simply filling the wrinkles themselves.

Is Rejuran Eye Effective for Fine Lines Under the Eyes?

If fine, crepey wrinkles are visible beneath the eyes even when the face is relaxed, Rejuran Eye may help improve skin regeneration and elasticity.

Under-eye fine lines tend to become more noticeable as the skin becomes thinner and drier.

For example, if several fine lines remain visible even when you are not smiling, or if foundation and concealer frequently settle into these lines, it may indicate reduced skin elasticity and moisture retention.

In these cases, simply reducing muscle movement may not be enough.

Fine, crepey wrinkles visible even at rest → Rejuran Eye

Deep crow's feet that appear when smiling → Botox

Both fine lines and expression wrinkles → A combination of treatments targeting skin quality and muscle movement

Understanding these differences helps determine the most appropriate treatment approach for wrinkles around the eyes.

What Is the Difference Between Rejuran Eye and Eye Botox?

Rejuran Eye focuses on improving skin regeneration and elasticity, while Botox reduces the muscle movements responsible for expression wrinkles.

Although both treatments address wrinkles around the eyes, they target different causes.

If the skin appears relatively smooth when the face is relaxed but crow's feet become prominent when smiling, muscle movement is likely a major contributing factor.

In this case, Botox may provide a more direct approach.

On the other hand, if the skin beneath the eyes appears thin and crepey, with multiple fine lines visible even without facial expressions, changes in skin quality may be the primary concern.

Crow's feet that appear when smiling → Botox
Fine under-eye wrinkles visible at rest → Rejuran Eye

Thin skin + Dryness + Reduced elasticity → Rejuran Eye

Both expression lines and fine skin wrinkles → Treatments addressing both causes

This is why not all wrinkles around the eyes should be treated in the same way.

Can Rejuran Eye Improve Dark Circles?

Rejuran Eye may ehlp improve the appearance of dark circles associated with thin skin, visible underlying blood vessels, or reduced skin elasticity. However, it cannot treat every type of dark circle.

Dark circles can develop for several different reasons.

In some cases, the skin beneath the eyes is so thin that underlying blood vessels become visible. In others, increased melanin pigmentation creates a brownish appearance.

Dark circles may also result from shadows caused by deep under-eye hollows.

Therefore, the treatment approach should depend on the color and underlying cause of the dark circles.

Thin skin with bluish or purplish discoloration → Consider skin regeneration treatments

Brown pigmentation around the eyes → Pigmentation treatments

Deep under-eye hollows → Volume Restoration

Protruding under-eye fat creating shadows → Structural under-eye correction

Among these concerns, Rejuran Eye primarily focuses on improving thin, weakened skin with reduced elasticity.

Rather than describing it simply as a "dark circle injection," it is more accurate to understand Rejuran Eye as a treatment that addresses skin-related factors that may contribute to dark circles.

Can Rejuran Eye Improve Hollow Under-Eyes?

Rejuran Eye may help improve fine lines and elasticity beneath the eyes, but it is not designed to create significant volume in deeply hollow areas.

It is important to distinguish whether the hollow appearance is caused by thinning skin or an actual loss of volume.

Rejuran Eye supports skin regeneration and may improve skin density and elasticity, but it does not provide immediate volume enhancement like dermal fillers.

Therefore:

Thin, crepey under-eye skin → Rejuran Eye
Under-eye hollowness that appears more noticeable due to fine wrinkles → Consider Rejuran Eye
Deep tear troughs → Volume Restoration treatments

Significant structural volume loss beneath the eyes → Treatments focused on restoring volume

The under-eye area requires particular care because excessive volume correction can sometimes create puffiness or unnatural contours.

For this reason, distinguishing between skin-quality concerns and volume-related concerns is essential.

Can Rejuran Eye Improve Under-Eye Bags?

If protruding under-eye fat is the primary concern, Rejuran Eye cannot remove the fat itself.

Under-eye puffiness may develop due to reduced skin elasticity, but it can also result from fat pads protruding forward beneath the eyes.

Because Rejuran Eye is a skin booster that supports skin regeneration, it does not remove or reposition protruding fat.

Therefore:

Thin under-eye skin with fine lines → Rejuran Eye

Reduced elasticity beneath the eyes → Rejuran Eye

Noticeably protruding under-eye fat → Structural treatments targeting under-eye fat

The most appropriate approach depends on the underlying cause of the puffiness.

What is the Difference Between Rejuran Eye and Rejuran Healer?

Both Rejuran Eye and Rejuran Healer contain PN and are designed to support skin regeneration.

Rejuran Healer is widely used to improve overall facial skin quality, elasticity, texture, and regeneration.

While Rejuran Eye has an adjusted viscosity that makes it more suitable for delicate skin around the eyes.

A simple way to distinguish them is:

Overall facial skin texture, elasticity and regeneration → Rejuran Healer

Fine lines and reduced elasticity around the eyes → Rejuran Eye

Concerns involving both the entire face and eye area → Use the appropriate treatment for each area

This does not mean Rejuran Eye is less effective than Rejuran Healer. Rather, the formulations are designed for different treatment areas and purposes.

What is the Difference Between Rejuran Eye and Juvelook?

Rejuran Eye uses PN to support skin regeneration and improve elasticity around the eyes, while Juvelook stimulates collagen production and is used to address concerns such as enlarged pores, uneven skin texture, and volume loss.

Although both treatments are associated with skin regeneration and collagen stimulation, their ingredients and primary purposes differ.

Rejuran Eye focuses on improving the quality of thin, dry, and weakened skin around the eyes, making it particularly relevant for under-eye fine lines and reduced elasticity.

Juvelook, on the other hand, contains PDLLA (Poly-D,L-lactic acid) and hyaluronic acid. It stimulates collagen production and may be used for a broader range of concerns, including enlarged pores, uneven skin texture, acne scars, and volume improvement, depending on the formulation and treatment technique.

Thin under-eye skin with fine lines→ Rejuran Eye

Enlarged pores, uneven texture, and reduced elasticity → Juvelook

Depressed acne scars + Collagen stimulation → Juvelook-based treatments

Understanding the primary treatment goal can help determine which option is more appropriate.

Does Rejuran Eye Make Under-Eye Skin Thickier?

Rejuran Eye does not immediately increase skin thickness like a filler. However, by supporting skin regeneration and collagen production, it may gradually improve the density and elasticity of thin, weakened skin around the eyes.

When the skin beneath the eyes becomes thinner, fine lines may become more visible, and underlying blood vessels or structures may show through more easily.

Rejuran Eye uses PN to support the skin's regenerative environment, aiming to improve firmness and reduce the appearance of fine wrinkles over time.

Therefore, rather than describing Rejuran Eye simply as an injection that "thickens the skin," it is more accurate to say that it aims to improve the overall quality, density, and elasticity of thin, aging skin around the eyes.

When Will I See Results From Rejuran Eye?

Results from Rejuran Eye are not immediate. Improvements generally develop gradually over several weeks as the skin undergoes its regenerative process.

Unlike dermal fillers, Rejuran Eye does not create its final result immediately after injection.

After PN is delivered into the skin, regenerative processes gradually take place, potentially improving skin texture, elasticity, and the appearance of fine lines.

Therefore, temporary swelling or raised bumps immediately after treatment should not be mistaken for the final results.

Immediately after treatment → Temporary raised bumps (embossing) and swelling may occur

Following days and weeks → Skin recovery and regenerative processes continue

Over several weeks → Gradual improvements in skin texture, elasticity and fine lines may become noticeable

The main purpose of Rejuran Eye is gradual skin-quality improvement rather than immediate volume enhancement.

How Many Sessions of Rejuran Eye Are Recommended?

Rejuran Eye is commonly performed as a series of treatments at regular intervals rather than relying on a single session.

Skin regeneration is a gradual process that generally cannot be completed through one treatment alone.

For individuals with significant fine lines or thinning skin, repeated treatments may be recommended to support gradual improvement, followed by maintenance sessions.

An initial treatment course may involve several sessions at relatively short intervals. Once the desired improvements are achieved, the intervals between treatments may be extended for maintenance.

In other words, Rejuran Eye is better understood as a progressive skin-regeneration treatment rather than a one-time injection that immediately fills under-eye wrinkles. The exact number of sessions and treatment intervals should be determined through consultation based on individual skin conditions.

How Long Deos Embossing Last After Rejuran Eye?

Small raised bumps, swelling, and redness may appear beneath the eyes after Rejuran Eye injections. These reactions usually subside naturally over time.

Because Rejuran Eye is injected directly into the skin, small raised injection marks may be visible immediately after the procedure.

The skin around the eyes is particularly thin, so embossing and swelling may appear more noticeable than in other facial areas.

Minor bruising may also occur.

If you have an important event, such as a photoshoot, wedding, or job interview, it is advisable to schedule your first treatment with enough recovery time rather than receiving it immediately before the event.

Is Rejuran Eye Painful?

Because the skin around the eyes is thin and sensitive, patients may experience stinging, pressure, or discomfort during the injection process.

Rejuran Eye is an injectable skin booster, so the treatment is not entirely painless.

The under-eye area may be particularly sensitive to needle insertion and the pressure of the injected product.

However, because the treatment area is smaller than that of full-face Rejuran, the procedure generally takes less time. Pain tolerance varies between individuals.

Is Rejuran Eye Necessary for People in Their 20s?

The need for Rejuran Eye depends more on the condition of the skin than on age alone.

Signs of aging around the eyes do not necessarily begin after the age of 40.

Individuals who naturally have thin or dry skin, frequently make facial expressions, or regularly rub their eyes may develop visible fine lines at a younger age.

Rejuran Eye may be considered if:

Concealer frequently settles into fine lines beneath the eyes

Fine wrinkles remain visible even when not smiling

The under-eye skin feels thin, dry, or rough

In these cases, a skin booster designed to support regeneration may be an option.

However, if there are no noticeable fine lines or signs of reduced elasticity, there is no need to begin treatment simply because of age.

When Can I Wear Makeup After Rejuran Eye ?

Because small injection marks and raised bumps may remain immediately after treatment, it is recommended to wait until the skin has settled before applying makeup.

On the day of treatment, avoid rubbing the eye area or pressing and massaging the raised injection sites.

When applying makeup, avoid using excessive pressure with brushes, sponges, or makeup puffs.

In particular, repeatedly rubbing or layering thick concealer to cover temporary bumps and swelling should be avoided.

What Precautions Should I Take After Rejuran Eye?

After treatment, avoid applying strong pressure or rubbing the eye area. It is also important to minimize heat exposure and irritation while temporary swelling and redness subside.

Avoid rubbing the skin around the eyes.

Do not press or massage raised injection bumps.

Avoid saunas, steam rooms, and excessive heat exposure.
Avoid strenuous exercise and excessive alcohol consumption during the initial recovery period.

Keep the skin moisturized and use appropriate sun protection.

Temporarily avoid harsh exfoliating treatments and scrubs.

Because the skin around the eyes is particularly thin and sensitive, minimizing unnecessary irritation is important during recovery.

Which Under-Eye Concerns Are Best Suited for Rejuran?

Rejuran Eye is most suitable for individuals who want to improve the quality of thin, dry, and weakened skin around the eyes rather than significantly increase under-eye volume or remove protruding fat.

Although different under-eye concerns may appear similar, their underlying causes can vary.

Crepey under-eye skin with multiple fine lines → Rejuran Eye
Thin skin and reduced elasticity around the eyes → Rejuran Eye
Dryness causing makeup to settle into fine lines → Rejuran Eye
Deep crow's feet that appear when smiling → Botox
Deep tear troughs creating shadows → Volume restoration
Protruding under-eye fat → Structural under-eye correction
Brown pigmentation-related dark circles → Pigmentation treatments
Thin skin with visible blood vessels contributing to dark circles → Consider skin regeneration treatment

Ultimately, the purpose of Rejuran Eye is not to fill the under-eye area with a large amount of product.

Instead, it aims to support gradual regeneration, helping thin and weakened skin become firmer and healthier over time.

By distinguishing between fine wrinkles, dark circles, and under-eye hollowness, patients can better understand the role of Rejuran Eye and choose a treatment approach suited to their specific concerns.

Rejuran Eye FAQ

Is Rejuran Eye Effective for Under-Eye Wrinkles?

Yes. Rejuran Eye is commonly used to improve fine, crepey wrinkles that remain visible even when the face is relaxed, as well as reduced elasticity in thin under-eye skin.

For crow's feet that mainly appear when smiling, Botox may be a more direct treatment option.

Can Rejuran Eye Eliminate Dark Circles?

Not all types of dark circles can be treated with Rejuran Eye. If dark circles are associated with thin skin and visible underlying blood vessels, improving skin quality may help reduce their appearance.

Can Rejuran Eye Fill Hollow Under-Eyes?

Rejuran Eye is not designed to fill deep under-eye hollows like dermal fillers. Instead, it focuses on improving the quality of thin, crepey skin with fine wrinkles.

Should I Choose Rejuran Eye or Rejuran Healer?

If your main concerns involve the under-eye area or skin around the eyes, Rejuran Eye may be more suitable. If your goal is to improve overall facial skin texture, elasticity, and regeneration, Rejuran Healer may be a better option.

Can Rejuran Eye Be Combined With Eye Botox?

Yes, both treatments may be considered when a patient has a combination of fine skin wrinkles and expression lines.

Rejuran Eye focuses on skin regeneration, while Botox reduces muscle movement. The suitability and timing of combined treatment should be assessed by the treating clinician.

Will Rejuran Eye Make My Under-Eyes Puffy?

Temporary raised bumps and swelling may appear immediately after the procedure. However, unlike fillers, Rejuran Eye is not intended to create lasting volume beneath the eyes.

Can Rejuran Eye Help if I Have Under-Eye Bags?

Rejuran Eye may help improve fine lines and reduced elasticity in the skin covering the under-eye area. However, it does not remove protruding under-eye fat. If fat protrusion is the primary concern, a structural treatment approach may be necessary.

Is One Session of Rejuran Eye Enough?

Some individuals may notice improvements in their skin condition after one session.

However, repeated treatments are commonly recommended when the goal is more substantial improvement in skin regeneration and fine lines.

Does Embossing Disappear Immediately After Rejuran Eye?

Small raised bumps may remain visible immediately after treatment and generally subside naturally over time.

Because the eye area has thin skin, swelling and embossing may be more noticeable than in other facial areas.

Can Rejuran Eye Help With Dry Under-Eyes That Cause Makeup to Look Patchy?

Rejuran Eye may help improve skin quality and moisture retention, potentially reducing the appearance of fine lines that cause makeup to settle unevenly. It may be particularly relevant when dryness and reduced elasticity contribute to concealer creasing or foundation appearing patchy beneath the eyes.
