Those searching for Hongdae Rejuran may be looking for a way to improve their skin condition without wanting to introduce foreign substances into the skin.

All skin care treatments ultimately aim to improve skin texture, wrinkles, and signs of aging, but the route to that destination differs from treatment to treatment.

Among them, skin boosters are one of the most sought-after aesthetic treatments because they are like the “vitamins” of aesthetic care, offering high satisfaction while helping improve the skin’s own regenerative ability.

Among these, the treatment I will introduce today is the representative skin booster: Rejuran.

Professional Background

Hello, I am Dr. Won-jin Cho, director of Chai Clinic.

After performing Rejuran treatments for many people in Hongdae for nine years, there is one comment I hear quite often.

“Rejuran provides such great satisfaction after treatment, but it hurts so much. Is there a Rejuran treatment that hurts less while still providing high satisfaction?”

Yes, although Rejuran provides excellent satisfaction, many people hesitate to receive the treatment because of the pain.

For those people, the product I would like to introduce today is Rejuran HB plus.

What Is Rejuran?

First, I will briefly explain Rejuran. Rejuran consists of polynucleotides, biocompatible substances extracted from salmon DNA.

The principle is to inject these polynucleotide ingredients into the dermal layer to induce skin regeneration.

It can greatly help with skin hydration and the reduction of fine lines, and can be considered a suitable skin booster for those who feel tightness deep within their skin. When the skin is dry from within and no topical moisturizing product provides satisfactory results, Rejuran can help replenish moisture within the skin.

Types of Rejuran

This is one of the reasons many people seek out Rejuran. In addition to improving overall skin condition, Rejuran offers a variety of products that can be used according to specific needs.

  1. Rejuran Healer

The representative Rejuran product, consisting of 100% polynucleotides. For those who can tolerate pain well and want to experience the full satisfaction of Rejuran, Rejuran Healer would be the most suitable choice.

  1. Rejuran i

Because it has low viscosity and high spreadability, it is useful for improving elasticity in thin areas such as fine lines around the eyes.

  1. Rejuran S

This product has slightly higher viscosity than Rejuran Healer and is suitable for treating acne scars or depressed scars.

  1. Rejuran HB plus

Yes, Rejuran HB plus is the product I would like to introduce to those who are just beginning to learn about Hongdae Rejuran.

Rejuran HB plus adds hyaluronic acid, a moisturizing ingredient, and lidocaine, an anesthetic ingredient, to the original Rejuran product. It provides additional hydration while significantly reducing pain compared with the original Rejuran Healer.

In addition to providing high satisfaction in terms of a dewy glow and hydration after treatment, it also reduces pain, making it one of the products I often recommend to people receiving Rejuran for the first time.

In conclusion, you can think of it as a product that preserves as much of Rejuran’s regenerative satisfaction as possible while minimizing pain through its anesthetic ingredient.

Hongdae Rejuran: Recommended Number of Treatments and Duration of Results

Rejuran is a treatment that strengthens the skin’s own regenerative ability, so it can be difficult to achieve noticeable satisfaction from just one treatment.

After treatment, you need to wait for the time required for collagen to build up with the help of the Rejuran ingredients.

Therefore, we generally recommend at least three to five treatments at intervals of two to three weeks.

With this treatment schedule, the results tend to remain satisfactory for approximately one season.

If you are looking into Hongdae Rejuran, it would be helpful to know how long the results may last.

What Are the Characteristics of Rejuran Treatment?

The more accurately Rejuran is injected into the dermal layer, the greater the satisfaction tends to be. An embossing effect, in which the injection sites become white and raised, also appears more clearly.

If a noticeable embossing effect appears after Rejuran treatment, it means that the treatment was performed successfully, so you do not need to be overly concerned.

If the injection reaches deeper than the dermal layer, however, it can increase pain while reducing satisfaction. The embossing effect also becomes less pronounced.

This embossing effect usually disappears within three days at most, so there should be no need for significant concern.

Today, I have explained Rejuran, a representative skin booster.

If you have been interested in receiving a skin booster but have hesitated because of the pain, starting with Rejuran HB plus may be a good option.

Above all, it is important to select the Rejuran product that suits you through a detailed consultation process and treatment planning.

I hope this information is helpful to those looking into Hongdae Rejuran. Thank you for reading.

This was Chai Clinic, customizing your beauty. Thank you.
