Scars that improve vs scars that waste your money


레이저와 큐어젯의 차이, 흉터 치료의 시너지를 만드는 법




Now that it’s spring,

I looked at some outdoor photos,

and my face,,

the scars looked way too severe.

So..

this is about CureJet. hehe




In today’s post,

let me first go over the key questions that come up often.


Q. Is CureJet

different from a laser?


A. Yes, it is not a laser.

I’ll explain in detail in the main text.


홍반부터 패인 흉터까지, 큐어젯을 활용한 복합 흉터 치료의 실제

Q. Is it effective even for depressed scars (ice-pick, boxcar, etc.)?



A. The effect varies depending on the type of scar.

Which cases it suits well

is covered specifically in the main text.


Q. Is one session enough?


A. No, usually multiple sessions are needed.

I’ll explain below how many sessions are realistic.



Starting with what CureJet is

— it is not a laser


This is something many people misunderstand,

CureJet is not a laser device.



More accurately, it is a needle-free injector

(a needleless injection device).


Using a high-pressure jet stream without needles,

it pushes medication

into the skin.


It delivers small shock waves to the skin

while simultaneously allowing medication

to penetrate to the dermis.


What makes this a bit confusing is,

from the outside it feels like something is being shot,

so

many people think it’s a laser.


But the mechanism is completely different.


Common agents used with CureJet are

  1. Rejuran (PDRN — a DNA repair component extracted from salmon)

  2. Hyaluronic acid

  3. Exosomes

  4. Growth factor complex

.


Depending on which agent is used,

the purpose differs slightly,


and for acne scars, ingredients that

promote skin regeneration are mainly used.



Which scars is it good for,

and which scars have limitations?


여드름 흉터 치료, 큐어젯과 레이저 병행이 필요한 이유


To be honest, CureJet does not

work well for every type of acne scar.


Let me share realistic expectations

by scar type.


Scar type

Characteristics

CureJet suitability

Erythematous scars (red marks)

Pigment is present but no depression

Good effect

Hyperpigmentation (brown marks)

Discoloration due to melanin deposition

Good effect

Rolling scars (gently depressed)

A broad, pressed-down skin contour

Can be used as an adjunct

Boxcar scars (vertically depressed)

Deep scars with clear borders

Limited as monotherapy

Ice-pick scars (deep, needle-like pits)

The deepest and narrowest form

Limited effect when used alone


But there is one important point here.

Just because a scar is deeply depressed

does not mean CureJet is completely meaningless.


When combined with procedures like

Fraxel, Infini, or CO2 laser, it can help improve

skin recovery, creating synergy.


It may be difficult to expect it to fill

depressed scars on its own, but


as one axis of combination therapy,

it definitely has value.


Director Wi Young-jin’s practical note:

In my experience, among patients who come in

for CureJet alone,

quite a few have ice-pick or boxcar scars

as their main concern.


In such cases,

I first explain honestly.


“These scars are hard to fill significantly with CureJet alone,

so it is better to consider

laser or subcision first.”


I also

always explain this in advance.


Still, if redness or pigmented marks

are present together,

using CureJet in combination can help

improve overall skin tone

more quickly in many cases.



The procedure and pain,

what is it actually like?


합정/홍대 여드름 흉터 고민, 큐어젯이 정답일까?


Just because CureJet has no needle

doesn’t mean it is painless.


Since it penetrates the skin with high pressure,

there is a brief, wedge-like刺激.


We do apply numbing cream before treatment,

and it varies by case,

but this is usually how I do it.


Apply numbing cream for 20–30 minutes, wipe it off,

then perform CureJet on the full face or

focused areas.


Treatment time is about 15–20 minutes.


Right after treatment, there may be slight erythema (redness)

and swelling,

but in most cases it subsides within the same day to the next day.


You can wash your face or do light moisturizing right away,

but strong friction or saunas

are best avoided for a few days.


Because recovery is relatively quick, office workers also

often schedule it during lunch breaks

or come after work.


Key summary:

CureJet is a needleless injection method

that delivers medication with high pressure.

It is effective for redness and pigmented scars, but

has limitations for deep depressed scars when used alone, so

combination treatment is recommended.



How many sessions are needed,

and how much does it cost?


큐어젯 시술 횟수와 비용, 현실적으로 얼마나 생각해야 할까?


This varies greatly by clinic, but

in my experience, for acne scar improvement,


at least 4–6 sessions are needed

for many people to feel noticeable change.


The price per session differs by clinic,

and also depends on which agent is used,

so it is hard to state

a fixed number here.


The downside is the cost ^^..


Among the agents, if exosomes or

special growth factors are included,

the cost rises much higher than Rejuran alone.


This is a bit unfortunate, but

because CureJet is a non-covered item,

pricing standards vary widely.


Before consultation, it’s good to check

which agent is being used

and the price of that agent in advance.


Still, compared to lasers, the shorter recovery time and

lower procedure burden

are clear advantages.



Frequently Asked Questions


Q1. While receiving CureJet,

can I also get other scar lasers?


A. Yes, you can. In fact, if you have deep scars,

CureJet is often combined before/after laser treatment

to enhance skin regeneration.


However, doing both on the same area

on the same day at once

should be judged based on skin condition.



Q2. What’s the difference between

Rejuran Healer injections and CureJet?


A. Rejuran Healer is injected directly into the dermis

with a needle,

while CureJet delivers medication

with a high-pressure jet without needles.


The ingredients may be similar, but

the depth and method of delivery are different.


People with needle phobia

often find CureJet

more comfortable.



Q3. Can I get it while I still have

active acne?


A. If there is a lot of active acne present,

it is best to adjust the treatment timing.


If treated over inflamed areas,

it can actually spread.


Usually, acne is first calmed down to some extent,

then scar treatment is started.


KakaoTalk consultation is also available before your visit.
