Rejuran vs Juvelook,

Which One Is Right for My Skin?

There's one question I've been hearing most

in the clinic lately.

"Doctor, Rejuran and Juvelook—

what exactly is the difference?"

Since both fall under the skin booster category,

a lot of people lump them together,

but the truth is, the ingredients, how they work,

and the skin conditions they're suited for are quite different.

If you choose a treatment without understanding this,

you may end up not getting the results you're after.

Today, I'll break down a proper comparison of the two.

💡 Key Takeaways

Q. How are the ingredients different?

A. Rejuran is pure PN (salmon DNA),

while Juvelook combines PDLLA with

HA (hyaluronic acid) into a complex formulation.

Q. Who is each one better suited for?

A. If your goal is skin regeneration and calming inflammation, go with Rejuran.

If you want both collagen stimulation and hydration,

Juvelook is the better fit.

Q. Can you get both at the same time?

A. Yes, you can.

But when and how you combine them

makes all the difference — I'll get into the details below.

It Starts with the Ingredients

— PN vs. PDLLA+HA

The key ingredient in Rejuran Healer is PN.

It's a DNA fragment derived from salmon,

and because it closely resembles the structure of human DNA, it has high biocompatibility

and plays a role in inducing tissue regeneration.

Juvelook takes things a step further.

It combines PDLLA, a regenerative ingredient,

with HA (hyaluronic acid).

Since HA draws in moisture,

you can think of it as a formula designed to target both regeneration and volume

at the same time.

Which Skin Type,

and Who Is It For?

This is a common misconception,

but Juvelook

is not an "upgraded version" of Rejuran.

They're two treatments with different goals.

Rejuran Healer is recommended if you:

• Have rough skin texture or noticeable pores

• Are mainly concerned about loss of elasticity

• Need skin repair after acne scarring

• Want to improve overall skin quality rather than add volume

Juvelook is a better fit if you:

• Want both volume improvement and skin regeneration at once

• Want to add hydration to thin areas like the eye area or forehead

• Are looking for a natural, subtle plumping effect

That said, just because Juvelook contains HA

doesn't mean it can fully replace fillers.

👨‍⚕️ Dr. Wi Young-jin's Clinical Note:

In my experience, for patients in their early to mid-30s, starting with Rejuran Healer

and observing the regenerative response first is often the right call.

That said, Rejuran works through cumulative effects,

so don't expect dramatic results from just one session.

Most people start to see a real difference

after at least 3–4 sessions.

One thing worth mentioning upfront:

because Juvelook has a thicker consistency, small bumps (papules)

may temporarily appear after treatment.

These typically resolve on their own within 1–2 weeks.

Treatment Process and Session Planning

Both treatments are injected directly into the dermis,

but they differ in injection depth and volume.

• Rejuran Healer

  Multiple small-point injections in a shallow layer

  
  
  

• Juvelook

  Evenly distributed into a slightly deeper, mid-layer

Session schedules also differ.

• Rejuran Healer

  Typically every 2–4 weeks, with 4 sessions as the standard course

  
  
  

• Juvelook

  Every 4 weeks, starting with around 3 sessions

Key Takeaway

Rejuran focuses on regeneration,

while Juvelook targets both regeneration and volume.

Choose based on what your skin actually needs.

Is It Better to Combine Both?

— Combination Cases

Rather than doing both on the same day,

I prefer setting a sequence

and alternating between the two.

For example: first build a regenerative base with Rejuran,

and once skin quality has improved,

then add volume with Juvelook.

It might seem like doing everything at once would give better results,

but the skin can only handle so much at once.

Spacing things out properly leads to better outcomes in the end.

Frequently Asked Questions (FAQ)

Q1. Rejuran vs Juvelook — which is better?

A. Neither one is superior across the board.

It comes down to whether you want to focus on regeneration

or add more volume.

Q2. Can one session make a difference?

A. These treatments are designed around cumulative results.

You'll typically need at least 3 sessions

before you start to notice a visible change.

Q3. Can I wear makeup right after treatment?

A. In most cases, you can from the next day.

If redness persists, though,

it's best to wait one more day.
