Results may vary depending on each individual’s skin condition, so we recommend having a thorough consultation with a medical professional.

If you are looking into skin boosters in Hongdae, you are probably experiencing dry skin or have recently started noticing fine lines more clearly.

That is why you may be looking into various options, such as Rejuran and Juvelook.

To help you decide whether Rejuran or Juvelook may be right for you, I will explain them briefly.

First, let’s look at what a skin booster is.

A skin booster is, as the name suggests, a treatment that improves the condition of the skin.

Rather than providing immediate satisfaction like Botox or fillers, it is often chosen as a long-term treatment or as part of an effort to prevent signs of aging.

When performed consistently and regularly, it can help promote the skin’s regenerative capacity and improve elasticity.

Among these treatments, Juvelook can be described as a product that made a significant breakthrough in the skin-booster field.

Rejuran, meanwhile, has become almost synonymous with skin boosters.

This may be why people searching for skin boosters in Hongdae find it difficult to choose between the two.

In fact, both products have clear advantages, so it is understandable that you may be unsure which one to choose.

For those who are deciding, I will explain the advantages of Juvelook and Rejuran,

as well as which skin booster may be suitable for different skin conditions.

Hello, I am Won-jin Jo, the director of CHAI Clinic, and I have been performing skin-booster treatments in Hongdae for nine years.

Having performed approximately more than 30,000 skin-booster treatments over the past nine years, I believe I can explain skin boosters in detail.

Let’s start with Juvelook.

Juvelook is a skin booster that increases skin volume by injecting a powder containing PDLLA into the skin.

The particles are very small and fine, which makes it possible to use them in the skin layer.

To give you an idea of how small these particles are, they are smaller than those in Sculptra, which I mentioned previously. Their melting point is also lower than that of Sculptra.

One advantage of Juvelook is that it can provide noticeable satisfaction by helping increase volume in the skin layer.

More specifically:

First, it may improve the appearance of fine lines.

Above all, if fine lines are left untreated, they can become deeper wrinkles and become more difficult to manage. If fine lines are a concern, it may be worth looking into Juvelook.

Second, it may help reduce the appearance of enlarged pores.

Enlarged pores are one of the skin concerns experienced by more people than you might expect.

In particular, many men become concerned when the pores around their cheeks and nose gradually become enlarged.

Juvelook may also be recommended for people with these concerns.

Third, it may help make lax skin look firmer.

In fact, this may be the main reason people search for skin boosters in Hongdae.

Many people seem to seek treatments that improve the condition of lax skin through the skin’s own natural abilities, rather than with Botox or fillers.

Among these options, Juvelook can provide a considerable level of satisfaction.

Then what are the disadvantages of Juvelook?

The main one is, again, pain.

It would be difficult to say that the treatment is only mildly painful.

However, the more accurately it is injected into the targeted subdermal layer, the greater the satisfaction may be. Therefore, those who tolerate the discomfort well may be able to see improved skin condition after treatment.

The second is the possibility of nodules.

As I mentioned previously, no treatment is completely free of side effects.

What matters is whether the side effect is serious or not.

In that respect, the side effects of Juvelook are generally not considered serious.

When the aforementioned PDLLA powder is injected into the skin, nodules may form if the substance is injected into a layer that is too shallow or if the particles do not dissolve properly and clump together.

Because this can be significantly affected by the practitioner’s technique and the recipient’s individual constitution, it is important to carefully assess the skin condition before receiving Juvelook.

Then what are the advantages of Rejuran?

Rejuran is composed of polynucleotides, a biocompatible substance extracted from salmon DNA.

This ingredient is injected into the dermal layer to promote skin regeneration.

In addition to helping reduce the appearance of wrinkles, it may improve elasticity and provide a feeling of increased skin hydration.

Overall, it can be described as a skin booster that helps support skin regeneration and skin health.

“ I have facial redness and some dermatitis. Can I still receive a skin booster?”

Yes, Rejuran is a skin booster that may be suitable for people with minor skin concerns.

There are roughly four types of Rejuran, allowing the product to be selected according to an individual’s skin condition and concerns.

They include Rejuran Healer, Rejuran HB Plus, Rejuran Scar, and Rejuran i.

Rejuran Healer focuses entirely on improving the condition of the skin and consists of 100% polynucleotides.

Among the Rejuran products, it is the one that can provide the highest level of satisfaction.

Rejuran HB Plus is designed to help reduce discomfort.

It combines the original Rejuran Healer with hyaluronic acid, a moisturizing ingredient, and lidocaine, a numbing ingredient.

It is often chosen by people who are sensitive to pain or who are receiving a skin booster for the first time.

Rejuran Scar is often used by people concerned about scars.

As its name suggests, Rejuran i is often used by people who need skin boosting around areas with thin skin, such as the eye area, or around mucous membranes.

Today, we looked at two leading products among the skin boosters available in Hongdae: Rejuran and Juvelook.

You may choose a skin booster based on the skin characteristics I mentioned earlier,

but the most important factors, as I always emphasize, are assessing your skin condition and having a detailed consultation.

It would be a good idea to look for a dermatology clinic that carefully assesses your skin and listens closely to your concerns.

I will conclude this post hoping that it provides the information needed by those who have searched for skin boosters in Hongdae.

This was CHAI Clinic, helping you customize your natural beauty.

Thank you.
