ABOUT REJURAN HB

What is Rejuran HB?

Rejuran HB adds hyaluronic acid to PN (Polynucleotide), the main ingredient of Rejuran, creating a skin booster that addresses skin recovery along with hydration and moisture.

It also contains lidocaine, a local anesthetic, which helps reduce discomfort during treatment, and treatment can be planned according to skin concerns such as dryness, dull texture and loss of firmness.

TREATMENT POINT

With PN and Hyaluronic Acid,
Caring for Skin Condition and Hydration Together

Dry environments, UV rays, aging and repeated irritation can break down the skin's hydration, firmness and texture.
Based on PN and hyaluronic acid, Rejuran HB addresses both the condition and hydration of tired skin.

POINT 01

PN + Hyaluronic Acid

A skin booster that adds hyaluronic acid to salmon-derived PN, considering both skin condition improvement and hydration.

02

Reduced Discomfort

Because it contains lidocaine, even those worried about the pain of injection treatments can consider it with relative comfort.

03

Hydration & Texture Improvement

Addresses skin that looks tired from lack of moisture, such as dry, dull skin and rough texture.

04

Natural-Looking Changes

Rather than heavily filling specific areas, we assess the skin's own firmness, texture and hydration to plan a natural direction of improvement.

Q&A

Rejuran HB Q&A

Q. What is the difference between Rejuran and Rejuran HB?

Both use PN as the main ingredient, but Rejuran HB also contains hyaluronic acid and lidocaine. It can be chosen when you want to consider hydration as well and reduce discomfort during treatment, and the right product is best decided after a diagnosis based on your skin condition and goals.

Q. Is the treatment less painful?

Rejuran HB contains lidocaine, a local anesthetic, which can help reduce discomfort during treatment. However, pain sensitivity varies from person to person, and numbing cream may also be used if needed.

Q. How many sessions are needed?

Treatment is generally performed over several sessions at regular intervals, but the recommended number of sessions and intervals vary depending on your skin condition, concerns and goals, so it is best to plan after a diagnosis.

Q. Can I return to daily activities right after treatment?

As with any injection treatment, redness, swelling, bruising, tenderness or temporary small bumps may appear depending on the individual. If you have an important schedule, we recommend planning with enough time in advance, and adjusting face washing, makeup and exercise after treatment according to our medical staff's guidance.

Q&A

What should I know before Rejuran HB?

What does Rejuran HB contain?

Rejuran HB is a skin booster that adds hyaluronic acid (HA) and the local anesthetic lidocaine to salmon-derived PN (polynucleotide). It cares for skin condition with PN and for hydration with hyaluronic acid at the same time.

Who is it suitable for?

It can be considered if your skin is dry and lacks hydration, if rough texture and fine lines are both a concern, or if you worry about injection pain. It suits people who want to improve the skin's own condition rather than add volume.

How do I choose between Rejuran HB and Rejuran Healer?

Both are based on PN, but if dryness is also a concern or you want to reduce discomfort, Rejuran HB is considered first. If sensitivity and skin regeneration are the main concerns, Rejuran Healer may suit you better, so the choice is made after diagnosis.

How is the treatment performed?

After cleansing and numbing cream as needed, it is injected with fine needles across the face or in the areas needed. Depth and amount are adjusted to your skin thickness and dry areas.

How long do the small bumps and recovery last?

The small raised bumps at injection points usually settle within about a day, while redness or slight bruising may last a few days. Schedule with some leeway before important events.

What are the aftercare instructions?

On the day of treatment avoid makeup and vigorous cleansing, and avoid saunas, alcohol and strenuous exercise for a few days. Consistent moisturizing and sun protection support recovery.

Who should not have Rejuran HB?

If you are pregnant or breastfeeding, have inflammation or wounds in the treatment area, or have had a hypersensitivity reaction to the same ingredient, treatment should be postponed or another option considered. Please tell us about your medication and medical history during consultation. Be sure to tell us if you are allergic to fish such as salmon or have ever reacted to local anesthetics such as lidocaine.

When will I see results and how long do they last?

A hydrated feel often comes relatively early, while texture and elasticity changes appear gradually over several sessions. Duration depends on your skin and lifestyle, so regular maintenance is recommended.

The number of sessions, duration of results and recovery time vary depending on individual skin condition. Details will be explained after consultation.
