Honestly, for people in their 20s, regenerative injections,

I was unsure about them at first too

Q. I'm in my 20s,

isn't Rejuran always the answer?

A. No. Depending on the skin condition in your 20s

there are quite a few people for whom Juvelook is a better fit.

Q. Why do recommendations differ even among people in their 20s?

A. Whether dermal damage comes first,

or volume and elasticity loss comes first

the target layer differs.

These days, among clients in their 20s in the clinic,

this is one of the most common questions I get.

"Doctor, should I get Rejuran or Juvelook?"

To be honest, even 5 years ago, I didn't usually recommend

regenerative injections to people in their 20s.

I thought, "Isn't it still too early?"

But after doing several hundred cases,

my thinking changed a bit.

There are definitely times when people in their 20s need regenerative injections,

and if you get them at the right time,

the effects last much longer.

So what exactly is different here?

Rejuran is a regenerative injection

that injects PN (polynucleotide) ingredients

extracted from salmon DNA into the dermal layer.

Unlike Juvelook, Rejuran

focuses on repairing skin damage itself and restoring the dermis,

and

Juvelook uses PDLLA (polylactic acid)

to induce collagen production and

is designed to boost volume and elasticity together.

This is where misunderstandings often arise

Key Insight

"In your 20s, Rejuran? Juvelook?

For 20-something clients in Hapjeong and Hongdae,

I’m sharing the criteria I actually use to recommend."

— Director Wi Young-jin (Beautystone Clinic, Hongdae)

Rejuran for your 20s, Juvelook for your 30s and up?

A lot of people think this,

but honestly, I don't use that formula.

I decide based on skin condition, not age.

A 28-year-old client who visited last month came in for acne scars,

had already received Rejuran four times elsewhere,

but said they didn't feel much effect.

When I examined the skin, the scars themselves were shallow,

but the cheek area had already lost elasticity,

and hollowing under the cheekbones had begun.

For someone like this, Rejuran alone isn't enough.

We combined it with Juvelook for two sessions,

and only then they said, "Ah, this is it."

Director Wi Young-jin's Key Summary

Being in your 20s doesn't automatically mean Rejuran is the answer.

If your main concerns are pores, scars, or oil-moisture imbalance, Rejuran is the choice,

but if you already see hollow cheeks and reduced elasticity,

Juvelook is the better fit.

If you have both, combining them is the right answer.

Customized Guide by Skin Type for Clients in Their 20s

Regenerative injections are still injections, so

bruising, swelling, and temporary nodules can occur.

With Juvelook in particular, lumps

can sometimes be felt early on.

Most settle within 2~3 weeks,

so I don't recommend it right before an important event.

The Three Most Common Questions in the Clinic

Q1. Rejuran and Juvelook,

can they be done together?

Yes, for combined types,

I actually recommend combining them more.

However, spacing them 2 to 4 weeks apart

reduces the risk of swelling and nodules

and is easier for the skin to tolerate.

Q2. How much does it cost, and how many sessions are needed?

Rejuran is usually 3~4 sessions at 3~4 week intervals,

and for Juvelook, about 2 sessions are enough for many people.

Results typically last around 8 to 12 months.

Q3. Any precautions after the procedure?

Avoid makeup, saunas, and alcohol on the day,

and avoid strong irritation for at least a week.

If you got Juvelook, gently massage the injection area 2~3 times a day

to help prevent lumping.

I'll go into this in more depth in the next post.
