'I’m looking into a skin booster in Hongdae,

which is better, Rejuran or Juvelook?

I have sensitive skin,

and since it’s my first time, I’m worried it might be too strong.'

These days, in a dry season like this, many people are considering skin booster procedures because their skin texture feels rough and their pores look larger, right?

When you search, Rejuran and Juvelook always appear side by side, but it’s easy to get confused about which one is right for your skin.

Today, for those who are thinking about a Hongdae skin booster for the first time, I’ll explain the differences between Rejuran and Juvelook and help you understand which procedure may be better for your skin.

Why are Hongdae

skin boosters necessary?

Many people think of skin boosters as just a kind of glow injection for the skin,

but in reality, they are closer to a regenerative treatment that helps skin cells recover on their own.

The skin is irritated every day by ultraviolet rays, oxidized sebum, fine dust, lack of sleep, and more.

When you are young and healthy, your skin recovers from this damage quickly, but as stress builds up and you get older, recovery slows down.

If you only moisturize at home with a cream or repair cream, the surface may feel temporarily hydrated, but that is all.

That is when a skin booster is needed.

A skin booster sends regenerative signals to the dermis, the layer responsible for elasticity and skin texture, encouraging cells to become active again.

Unlike moisturizing, which only makes the surface feel hydrated for a short time, it aims to bring about “fundamental recovery” from within the skin.

Why Rejuran and Juvelook are similar, yet different

Rejuran is made with PN (polynucleotide), a component extracted from salmon DNA.

This ingredient sends a signal to fibroblasts in the skin to “work again,” helping repair damaged cell DNA and restore the skin’s basic resilience.

That is why it is especially effective for people whose skin is sensitive and dry, who reddens easily, or whose skin feels tight even after washing.

One to two weeks after a Rejuran procedure,

“Skin texture becomes smoother, and makeup goes on much better.”

People often say things like this.

On the other hand, Juvelook uses an ingredient called PDLLA (polylactic acid).

Our body recognizes this ingredient as a foreign substance and triggers a defense response,

and in that process, fibroblasts become active and create new collagen.

That is the principle behind how the skin gradually fills out and gains density over time.

The immediate feeling of hydration is less noticeable than with Rejuran, but after 3 to 4 weeks you may notice improved volume and tighter pores.

You can also receive the two procedures together.

If Rejuran helps restore the cells first, Juvelook then adds elasticity on top of that, creating a synergistic effect.

If you want skin that feels hydrated inside and firm on the outside, combining the two procedures can be an option.

Post-procedure care and maintenance tips

Whether it is Rejuran or Juvelook, your skin is sensitive for the first 2 to 3 days after the procedure.

During that time, cleanse gently with lukewarm water and avoid rubbing the skin or using scrubs.

Makeup should be kept to a minimum, and it is best to apply only moisturizer or a repair cream.

Also, many people ask after the procedure, “Will the redness last long?”

With Rejuran, tiny injection marks may remain for about a day, and Juvelook often passes with almost no redness.

From the next day, you can go about your daily life, and after 3 days you will likely feel that your skin is more hydrated and its texture is smoother.

At this time, make sure to get enough water, sleep, and sun protection.

Especially if you often walk around the sun-exposed streets of Hongdae,

sunscreen with SPF 50 or higher is a must.

Even with this kind of care, if you only do it once and stop, your skin can become dry again and lose elasticity.

The effects of a skin booster are much more stable when it is performed more than three times at 3- to 4-week intervals, rather than just once.

Please also keep in mind that maintaining it steadily over a period of time is the way to keep your skin elastic for longer.

If you are considering a Hongdae skin booster procedure,

  1. Get an accurate diagnosis of your skin condition before the procedure,

  2. Avoid irritation for 2 to 3 days after the procedure and focus on moisturizing and repair care,

  3. Continue consistently at 3- to 4-week intervals for at least 3 sessions,

your skin texture and elasticity will clearly be different.

A skin booster is a procedure that opens the way for the skin to recover healthily on its own.

Good skin is not something you are simply born with; it is something you build consistently.
