The change of seasons, when the weather gradually warms and temperatures become pleasant for outdoor activities, can actually be a more concerning time for people with sensitive skin.

Those of you who have searched for Hongdae skin boosters may also be more concerned about deteriorating skin condition caused by yellow dust and fine dust than happy about the warming weather.

For those people, today's topic is “skin boosters.”

For those looking into Hongdae skin boosters, I will discuss the types and characteristics of representative skin boosters, as well as precautions to keep in mind.

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

Weather like this is ideal for going out, but it also clearly has drawbacks: fine dust, yellow dust, and soon, pollen will be floating in the air.

Having practiced aesthetic dermatology in Hongdae for nine years, I have seen more people come in for skin care during this short change-of-seasons period than ever before.

That makes me think this may be one of the most difficult seasons for skin care.

For those with these skin concerns, the treatments I would like to introduce today are the two leading skin boosters: Rejuran and Juvelook.

First, skin boosters are known as the “vitamins” of aesthetic dermatology.

Although there is a generally recommended treatment interval, like vitamins, they are treatments that can be beneficial whenever you have the time and financial flexibility to receive them.

But just as there are various ways to take vitamins, there are also various types of skin boosters, right?

For those looking into Hongdae skin boosters, I will introduce two well-known skin “vitamins.”

First is Rejuran. Rejuran can be considered the “generic name” of skin boosters.

It is a treatment that injects a substance called polynucleotide into the dermal layer of the skin to promote skin regeneration and improve elasticity.

Since there are various types of Rejuran, you can choose a product suited to your individual skin condition.

In brief, there are Rejuran Healer, Rejuran HB Plus, Rejuran i, and Rejuran Scar.

Rejuran Healer is a product composed of polynucleotides and is recommended for those who want to focus entirely on skin health.

Rejuran HB Plus is made by adding lidocaine, an anesthetic, and hyaluronic acid, a moisturizing ingredient, to Rejuran Healer.

As you can tell from the inclusion of lidocaine, an anesthetic, Rejuran treatments can be fairly painful.

The same applies to Juvelook as well as Rejuran.

However, because Rejuran HB Plus contains an anesthetic, it is often recommended for people trying a skin booster for the first time.

Rejuran i is mainly used on areas where the skin is thin.

Finally, Rejuran Scar is a suitable skin booster product for those concerned about scars.

Rejuran is a skin booster specialized in skin regeneration and skin health.

Some of you who have searched for Hongdae skin boosters may have concerns like these:

“Nothing is visibly wrong, but why does my skin feel so uncomfortable underneath? It feels tight.”

Yes, Rejuran may be suitable for people in this situation.

As mentioned earlier, polynucleotides have a high affinity for water, helping the skin feel comfortable and hydrated from within.

By making the skin feel comfortable and moisturized from within, it promotes overall skin regeneration and elasticity.

Although results vary from person to person, it is generally difficult to achieve noticeable satisfaction from Rejuran after just one treatment.

The same applies to Juvelook. Due to the nature of skin boosters, repeated treatments are generally used to extend the duration of satisfaction.

Rejuran is generally recommended three to five times at intervals of three to four weeks.

Next is Juvelook.

Juvelook can be described as a product that marked a groundbreaking development in the field of skin boosters.

It is a treatment in which a polymer called PDLLA is diluted in water for injection and injected into the subdermal layer.

Because the particles are extremely small and fine, it can also be used in the skin layers.

Also called a “collagen stimulator,” Juvelook stimulates collagen to promote regeneration.

As a result, it is a skin booster that helps make the dermal layer thicker.

Juvelook is a product that helps directly increase the thickness of the skin layers.

It helps improve fine lines, tighten enlarged pores, and make sagging skin look firmer.

As mentioned earlier, Juvelook is also generally recommended at least three times.

“Three or more treatments at intervals of four to five weeks” can be considered the standard process.

It is a skin booster often recommended for people whose skin feels dull or rough, or whose fine lines are noticeable.

So, today I introduced two representative skin boosters: Rejuran and Juvelook.

As mentioned, skin boosters are the vitamins of aesthetic dermatology, so you do not necessarily have to follow the generally recommended number of treatments without exception.

If you are highly satisfied after one or two treatments, you do not have to receive additional treatments. Conversely, if you still feel that something is lacking after three or more treatments, you may choose to receive additional treatments.

Most importantly, the practitioner's level of skill matters.

For skin booster treatments, it is important to inject an appropriate amount into the precise target layer.

This is because it can not only improve satisfaction but also reduce side effects such as nodules.

Those looking into Hongdae skin boosters should be sure to keep this in mind.

In addition, based on the information I shared today, you may consider which skin booster might generally suit you.

It would be best to determine the more detailed aspects through a thorough consultation at the dermatology clinic you visit.

As I always say, no two people in the world have exactly the same skin condition.

I hope those of you who searched for Hongdae skin boosters found the information you needed. With that, I will conclude.

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