Hello.
I am Dr. Joh Bo-hwang, head physician at Cleor Clinic Gangnam.
"I've been looking into Fraxel because I heard it's good,
but some places recommend a CO2 laser. What's the difference?"
"I want something with a short downtime,
but I don't know which procedure to choose."
One of the most common crossroads for people looking into laser treatments for the first time
is precisely these two options.
Fraxel and CO2 lasers are both used for skin regeneration and texture improvement,
but they differ in how they work, the skin concerns they address,
and the recovery period.
Today, I will explain how these two procedures differ,
and which direction is right for those with specific concerns.
Why are there so many types of laser treatments?
Dermatological laser treatments are broadly divided into two categories:
Ablative lasers
Ablative lasers work by directly removing a portion of the skin's surface,
thereby stimulating the dermal layer.
In simple terms,
the process involves“slightly burning and peeling off the skin → allowing new skin to grow.”
Collagen production increases during the wound healing process → improving the skin.
Because the surface is physically resurfaced,
the effects can be relatively noticeable,
but it requires more recovery time.
Non-ablative lasers
Non-ablative lasers deliver heat stimulation only to the dermal layer,
while maintaining the skin's surface.
There is less surface damage, so the recovery burden is relatively low,
but it often takes longer for the effects to appear.
Fraxel and CO2 lasers are representative procedures of these two methods, respectively.
What is Fraxel?
Fraxel works by
creating columns of microthermal damageat regular intervals.
The stimulated areas undergo a natural healing process,
which induces collagen regeneration, and the surrounding undamaged tissue
helps with recovery.
For this reason, the recovery burden is less compared to methods that peel the entire skin,
and it is often chosen by those who want to maintain their daily routine while undergoing treatment.
It is mainly used to improve pores, skin texture, fine wrinkles, and acne scars.
What is a CO2 laser?
The CO2 laser is a representative ablative laser treatment.
It uses carbon dioxide gas to remove
damaged tissue on the skin's surface while simultaneously
applying heat stimulation to the dermal layer to induce collagen regeneration.
Because it directly resurfaces the surface, it is often used to improve deep scars or
significant skin irregularities.
However, the recovery period after the procedure may be longer than with Fraxel,
and redness may persist for a certain period depending on the individual,
so it is important to schedule the procedure with ample time to spare.
Guidance by Skin Concern
Which of the two procedures is more suitable depends on the skin condition and goals.
When Fraxel may be considered first
For those who cannot afford a long downtime due to work or daily life,
for those whose primary goal is to improve pores and skin texture,
for those who want to gradually refine the overall texture of their skin,
and for those with acne scars that are not deep, we may recommend Fraxel first.
When a CO2 laser may be considered first
For those concerned about deep and noticeable acne scars or skin irregularities,
for those who can secure sufficient recovery time,
for those whose purpose is to remove specific lesions such as moles or warts,
and for those who expect relatively noticeable changes with a single procedure, we tend to recommend CO2 laser.
Of course, the two procedures can also be performed sequentially in combination.
The appropriate sequence and combination
will be determined after directly examining the skin condition.
Precautions Before and After Treatment
Common Precautions
Avoid saunas, strenuous exercise, and alcohol for one week after the procedure.
Apply sunscreen thoroughly when going out.
It is important not to pick at or irritate the treated area.
If you are pregnant or breastfeeding, be sure to consult with a healthcare provider before deciding on the procedure.
Additional Precautions After CO2 Laser Treatment
During the recovery period, there may be oozing or scabbing,
and it is best not to remove them arbitrarily.
To prevent pigmentation, be even more diligent with sunscreen and moisturizing care.
The recovery period varies from person to person,
so it is best to schedule the procedure with sufficient time before any important events.
Frequently Asked Questions (FAQ)
Q. Fraxel vs. CO2 Laser: Which is the better treatment?
Fraxel has less damage to the skin surface, resulting in a relatively faster recovery,
and is suitable for improving pores, fine wrinkles, pigmentation, and skin texture.
Generally, gradual effects are achieved through multiple treatments.
On the other hand, the CO2 laser removes a portion of the epidermis to stimulate collagen regeneration,
making it suitable for improving deep scars, wrinkles, and skin texture,
but the recovery period is about 1-2 weeks, so it is best to plan the procedure in advance.
Q. How many Fraxel sessions are needed to see results?
It depends on the skin condition and goals,
but generally, people experience
gradual changes after about 3-5 sessions.
The recommended interval between treatments is about 4-6 weeks,
and skin improvement is achieved through cumulative effects rather than expecting a significant change at once.
Q. What is the downtime for a CO2 laser?
It varies depending on the individual's skin condition and the extent of the procedure,
but it is generally recommended to schedule with at least 1-2 weeks of buffer time.
Q. I'm concerned about both pores and acne scars. Which treatment is right for me?
It depends on the depth of the scars and the condition of the pores.
Fraxel is often considered first for superficial pores and shallow scars,
and CO2 laser or combination treatments may be recommended for deep and noticeable scars.
A direct examination is required to make a determination.
Q. Can I get both treatments together?
Sequential combination may be possible depending on the skin condition.
However, performing them at once can increase the irritation to the skin,
so it is important to design the sequence and interval through consultation.
Fraxel and CO2 lasers have the same goal but
are different approaches.
Rather than asking which treatment is better, it is important to first understand what choice is best for your current skin condition, concerns,
and lifestyle.
At Cleor Clinic Gangnam, we carefully examine the skin condition before the procedure,
and provide guidance tailored to each individual's situation.
