Rejuran is a polynucleotide (PN)-based injectable treatment used to improve overall skin quality, including fine lines, texture, elasticity, and hydration. At Cheongdam JCELL Dermatology Clinic, Rejuran treatment can be planned by a dermatologist according to the patient's skin condition, treatment area, degree of aging, and individual aesthetic goals.

Unlike conventional dermal fillers that primarily add or restore facial volume, Rejuran is generally used as a skin-quality treatment. Clinical research has investigated Rejuran and other polynucleotide treatments for improvements in wrinkles, skin texture, elasticity, and tissue quality.

What Is Rejuran?

Rejuran is a polynucleotide-based injectable treatment developed for skin rejuvenation.

Polynucleotides are used in aesthetic dermatology as skin boosters with the goal of supporting tissue remodeling and improving overall skin condition. A survey of Korean board-certified dermatologists found that PN injections are widely used in clinical practice, particularly for facial fine lines, uneven texture, dry skin, and other skin-quality concerns.

Rejuran may be considered for patients concerned about:

• Fine lines
• Uneven skin texture
• Reduced elasticity
• Dry or dehydrated-looking skin
• Enlarged-looking pores
• Dull complexion
• Early signs of skin aging
• Overall skin quality

Why Choose a Dermatologist for Rejuran?

Rejuran treatment is not simply about injecting the same amount of product into every patient.

Skin thickness, elasticity, facial anatomy, treatment history, and the location of fine lines can differ significantly from one person to another.

A dermatologist can assess:

• Skin texture
• Hydration
• Elasticity
• Fine lines
• Pore visibility
• Skin thickness
• Treatment areas
• Previous injectable procedures
• Overall skin condition

This allows the treatment approach to be adjusted according to the patient's actual skin concerns.

Rejuran for Fine Lines

Fine lines are among the most common reasons patients consider Rejuran.

As skin ages, changes in collagen, elasticity, hydration, and tissue structure can make fine lines increasingly visible.

Rejuran may be considered for fine lines around areas such as:

• Cheeks
• Under-eye area
• Forehead
• Around the eyes
• Other areas with superficial skin aging

A clinical trial evaluating Rejuran for crow's feet found improvements in wrinkle-related measures and skin surface characteristics, although results can vary according to treatment protocol and individual response.

Rejuran for Skin Texture & Pores

Uneven texture and enlarged-looking pores can become more noticeable when the skin loses elasticity or becomes dehydrated.

Rejuran may be incorporated into a treatment plan when the goal is to improve overall skin quality rather than simply conceal individual pores.

A study of intradermal polynucleotide treatment reported improvements in pore appearance and skin thickness among some younger patients, while other age groups showed improvements in wrinkles, skin tone, and sagging.

The underlying cause of enlarged pores should still be assessed because sebum production, acne, follicular structure, and loss of elasticity may all contribute.

Rejuran for Skin Hydration

Dry or dehydrated-looking skin can make fine lines and uneven texture more noticeable.

Polynucleotide treatments are used in aesthetic dermatology with the aim of supporting skin hydration and tissue quality. Expert perspectives on PN treatments describe proposed mechanisms involving a hydrophilic matrix that may support tissue remodeling and hydration.

Rejuran may therefore be considered for patients who want skin that appears:

• More hydrated
• Smoother
• Softer
• More supple
• Healthier-looking

The appropriate treatment depends on the patient's skin condition and whether dehydration is the primary concern.

Rejuran for Skin Elasticity

Reduced elasticity is a common feature of aging skin.

As the skin gradually loses structural support, fine lines, sagging, and changes in texture may become more noticeable.

Rejuran may be considered as part of a skin-quality treatment plan for patients experiencing reduced elasticity.

Clinical research involving Rejuran has reported changes in elasticity and collagen-related measures, although the evidence base for polynucleotide treatments remains limited and treatment outcomes can differ between studies.

Rejuran for Under-Eye Skin

The under-eye area has relatively thin and delicate skin, making fine lines and reduced skin quality particularly noticeable.

Rejuran may be considered for selected patients concerned about:

• Under-eye fine lines
• Thin-looking skin
• Reduced elasticity
• Dehydrated-looking under-eye skin
• Early signs of aging

Because the periocular area contains important anatomical structures, treatment should be carefully planned according to the patient's anatomy and skin condition.

Rejuran for Acne-Related Texture

Previous acne can leave behind uneven texture, enlarged-looking pores, and superficial scars.

Rejuran may be incorporated into a broader treatment plan when improving overall skin quality and tissue condition is part of the goal.

However, deeper atrophic acne scars involve structural changes that may require procedures specifically designed for scar remodeling, such as subcision, laser treatment, or other combination approaches.

Polynucleotide-based treatments have also been investigated for scar-related applications, although further research is needed to establish optimal protocols.

Rejuran vs. Skin Boosters

“Skin booster” is a broad category rather than the name of a single treatment.

Different skin boosters may contain hyaluronic acid, polynucleotides, or other materials and can have different treatment goals.

Rejuran is a specific polynucleotide-based treatment commonly used for skin-quality concerns such as fine lines, texture, elasticity, and hydration.

The choice between Rejuran and another skin booster depends on the patient's skin condition and the primary treatment objective.

Rejuran vs. Dermal Fillers

Rejuran and traditional dermal fillers are designed for different purposes.

Rejuran focuses primarily on skin quality and regenerative or tissue-supportive treatment.

Dermal fillers are generally used to restore or add facial volume and can be selected for contouring or structural correction.

For patients who are satisfied with their facial shape but want to improve the quality of their skin, Rejuran may be considered instead of a conventional volumizing filler.

How a Dermatologist Plans Rejuran Treatment

1. Skin Consultation

The dermatologist reviews the patient's skin concerns, medical history, previous aesthetic procedures, medications, allergies, and treatment goals.

2. Skin Assessment

Skin hydration, texture, elasticity, fine lines, pore appearance, and treatment areas are evaluated.

3. Customized Treatment Plan

The treatment area, injection depth, technique, amount, and treatment schedule are determined according to the patient's skin condition.

A survey of Korean board-certified dermatologists found that many PN users favor intradermal serial-puncture techniques, although approaches vary between practitioners and treatment goals.

4. Rejuran Injection

Rejuran is administered into the planned treatment areas using an appropriate injection technique.

5. Post-Treatment Care

Aftercare guidance is provided according to the treatment area and individual skin condition.

Rejuran Recovery & Downtime

Rejuran is an injectable treatment, so temporary reactions at the injection sites can occur.

Patients may experience:

• Redness
• Swelling
• Small bumps
• Tenderness
• Bruising
• Temporary sensitivity

These effects generally settle as the treated skin recovers, but the duration varies between individuals.

Patients should follow their dermatologist's specific aftercare instructions and avoid unnecessary irritation during the initial recovery period.

Rejuran Results & Treatment Course

Rejuran is generally approached as a gradual skin-quality treatment rather than an immediate volumizing procedure.

As the skin responds to treatment, patients may notice improvements in:

• Skin texture
• Fine lines
• Hydration
• Elasticity
• Pore appearance
• Overall skin quality

Treatment schedules vary according to the product, treatment area, skin condition, and individual goals.

A survey of Korean board-certified dermatologists found that three PN treatment sessions spaced approximately four weeks apart were commonly recommended among respondents who used PN injections. This represents a practice pattern rather than a universal treatment requirement.
