Rejuran Healer vs Rejuran I: What’s the Difference?
Rejuran Healer vs Rejuran I: What’s the Difference?
Rejuran Healer and Rejuran I are two formulations within the Rejuran family, but they are designed for different treatment areas. Both use polynucleotide (PN) as the primary ingredient, yet their formulation characteristics and intended applications differ.
The simplest way to understand the difference is:
- Rejuran Healer: Designed primarily for broader facial skin rejuvenation and overall skin quality
- Rejuran I: Designed specifically for thin, delicate skin around the eyes
Choosing between them is less about which product is “stronger” and more about matching the formulation to the thickness and needs of the treatment area.
What Is Rejuran Healer?
Rejuran Healer is the original and most widely recognized Rejuran formulation. It contains purified polynucleotides and is primarily used for broader facial skin-quality improvement.
It may be considered for:
- Fine lines
- Reduced skin elasticity
- Uneven skin texture
- Dull-looking skin
- Enlarged-looking pores
- Early signs of skin aging
- General facial skin rejuvenation
- Skin that appears thin or less resilient
Rejuran Healer is generally used across larger facial areas rather than being limited to the delicate eye area.
Its goal is not to create conventional filler-like volume. Instead, treatment focuses on gradually improving the overall condition and quality of the skin.
What Is Rejuran I?
Rejuran I is a Rejuran formulation specifically intended for thin and delicate skin, particularly around the eyes.
The official Rejuran product lineup identifies Rejuran I for thin skin, while the product information describes its treatment area as the crow's-feet and thin-skin areas.
It may be considered for:
- Under-eye fine lines
- Crow's feet
- Thin under-eye skin
- Reduced elasticity around the eyes
- Early signs of aging around the eye area
The formulation has lower viscosity than standard Rejuran, making it more appropriate for delicate areas where a lighter formulation may be preferred.
Rejuran Healer vs Rejuran I: Main Difference
Both products are based on PN, so the main difference is formulation characteristics and intended treatment area.
Rejuran Healer
- Primary ingredient: PN
- Intended area: Broad facial treatment
- Formulation: Medium viscosity
- Main focus: Overall skin quality and rejuvenation
- Common concerns: Fine lines, elasticity, texture, aging skin
Rejuran I
- Primary ingredient: PN
- Intended area: Thin and delicate skin
- Formulation: Lower viscosity
- Main focus: Eye-area skin quality
- Common concerns: Under-eye fine lines and crow's feet
Therefore, Rejuran I should not simply be thought of as a weaker version of Rejuran Healer. It is designed with a different treatment area in mind.
Which Is Better for the Under-Eye Area?
For under-eye skin, Rejuran I is generally the more appropriate formulation.
The skin around the eyes is particularly delicate, and treatment requires careful consideration of product characteristics, injection depth, and technique.
Rejuran I may be considered for:
- Fine lines under the eyes
- Crow's feet
- Thin-looking under-eye skin
- Reduced elasticity
- Early age-related changes
It is important to distinguish this from treating dark circles caused primarily by pigmentation, visible blood vessels, tear-trough volume loss, or facial anatomy. Rejuran I may improve skin quality, but it cannot correct every cause of dark circles.
Which Is Better for Full-Face Rejuvenation?
For overall facial skin quality, Rejuran Healer is generally the more appropriate option.
It can be used across areas such as:
- Cheeks
- Forehead
- Lower face
- Around the mouth
- Other areas with fine lines or reduced elasticity
The treatment can target broader concerns rather than focusing exclusively on the thin skin around the eyes.
If the patient wants both full-face rejuvenation and under-eye treatment, a provider may use Rejuran Healer for the face and Rejuran I around the eyes rather than using one formulation everywhere.
Rejuran Healer vs Rejuran I for Fine Lines
Both can improve the appearance of fine lines, but the location of the wrinkles is important.
Rejuran Healer may be more suitable for:
- Cheek fine lines
- Forehead fine lines
- Around-the-mouth lines
- General facial skin aging
- Fine lines accompanied by poor overall skin quality
Rejuran I may be more suitable for:
- Under-eye fine lines
- Crow's feet
- Fine lines associated with thin eye-area skin
- Delicate skin around the eyes
The objective is not simply to select the formulation with the highest concentration. Instead, the product should be matched to the anatomical characteristics of the area being treated.
Rejuran Healer vs Rejuran I: Treatment Process
Both treatments involve multiple small injections, but the treatment area and injection strategy differ.
Rejuran Healer
A typical treatment may include:
- Skin assessment
- Cleansing and preparation
- Topical numbing
- Multiple injections across the selected facial areas
- Post-treatment care
Small raised bumps, redness, swelling, or bruising may temporarily appear.
Rejuran I
The process is similar, but treatment is concentrated around delicate areas such as the under-eyes and crow's feet.
Because the eye area is sensitive, the provider needs to carefully consider:
- Injection depth
- Injection volume
- Product distribution
- Anatomical structures
- Patient sensitivity
Rejuran I should therefore be administered by a qualified medical professional experienced with periocular injections.
Is Rejuran I Less Painful Than Rejuran Healer?
Not necessarily.
Both treatments involve multiple injections, so some discomfort can be expected. The eye area can also be particularly sensitive.
Pain can vary depending on:
- Injection technique
- Number of injection points
- Treatment area
- Individual pain sensitivity
- Use of topical numbing
- Provider technique
Rejuran I's lower-viscosity formulation is designed for the thin-skin treatment area, but this does not mean that the procedure is automatically painless.
Patients who are concerned about discomfort should discuss available numbing and comfort measures before treatment.
What Results Can You Expect?
Both treatments are intended to improve skin quality gradually rather than create an immediate volumizing effect.
Rejuran Healer
Patients may gradually notice:
- Smoother-looking skin
- Improved elasticity
- Softer fine lines
- More refined texture
- Healthier-looking facial skin
Rejuran I
Patients may gradually notice:
- Smoother under-eye skin
- Softer-looking fine lines
- Improved appearance of skin elasticity
- Better overall quality of the delicate eye area
Results vary according to age, skin condition, treatment protocol, and individual response.
Temporary injection bumps or swelling can make the area look different immediately after treatment, so the final result should not be judged during the first few days.
How Many Rejuran Healer or Rejuran I Sessions Do You Need?
Both treatments are commonly performed as part of an initial treatment series when the goal is progressive skin-quality improvement.
A Korean clinic may recommend:
- Around 3 initial sessions
- Approximately 2–4 weeks between sessions
- Individualized maintenance afterward
However, the exact schedule depends on:
- Skin condition
- Treatment area
- Age
- Degree of fine lines
- Previous treatments
- Desired outcome
- Individual response
The under-eye area may require a more conservative treatment plan because of its delicate anatomy.
Can You Use Rejuran Healer and Rejuran I Together?
Yes, a provider may use both formulations in the same overall treatment plan when different facial areas have different needs.
For example:
- Rejuran Healer: Full-face skin-quality treatment
- Rejuran I: Under-eye and crow's-feet treatment
This approach allows the formulation to be matched to the characteristics of each area rather than applying the same product everywhere.
Whether they should be administered during the same visit depends on the patient's skin condition, treatment plan, and provider's judgment.
Rejuran Healer vs Rejuran I: Which One Should You Choose?
A simple way to choose is to identify the primary treatment area.
Choose Rejuran Healer If:
- You want full-face skin rejuvenation.
- Your main concerns are texture and elasticity.
- You have fine lines across several facial areas.
- Your skin appears dull or less resilient.
- You want broader improvement in overall skin quality.
Choose Rejuran I If:
- Your primary concern is the eye area.
- You have under-eye fine lines.
- You have crow's feet.
- The skin around your eyes is thin or delicate.
- You want a formulation specifically intended for thin skin.
Consider Both If:
- You want full-face rejuvenation and under-eye treatment.
- Your facial skin and eye-area skin have different needs.
- Your provider recommends different formulations for different anatomical areas.
The choice should be based on where the treatment is needed, not simply on which product sounds more powerful.
Final Thoughts
Rejuran Healer and Rejuran I contain the same core PN-based technology but are designed for different applications. Rejuran Healer is generally used for broader facial skin rejuvenation, while Rejuran I is specifically designed for thin and delicate areas such as the under-eye region and crow's feet.
If your main concern is overall facial texture, elasticity, fine lines, and skin quality, Rejuran Healer may be the more appropriate option. If your concern is specifically thin under-eye skin and fine lines around the eyes, Rejuran I is generally better suited to that area.
For patients with concerns across the entire face and around the eyes, a combination of Rejuran Healer for the face and Rejuran I for delicate eye-area skin may be considered as part of an individualized treatment plan.
