Hello.
I am Dr. Cho Hyuk-chan, head physician at Cleor Clinic Uijeongbu.
Recently, among those looking into laser treatments,
one of the most frequently asked questions is,
“Which should I choose, Fraxel or CO2 laser?”That is the question.
I looked into Fraxel because it's supposed to be good,
but some clinics recommend CO2 laser, and
many people are concerned because they don't know the selection criteria.
Both treatments aim to regenerate the skin and improve texture, but
the approach, suitable skin concerns, and recovery speed are different.
In this article, we will summarize the characteristics of each laser and
selection points for each skin concern.
Ablative and Non-ablative Lasers
Laser treatments used in dermatology can be
largely divided into two methods.
Ablative lasers remove part of the skin surface while
delivering stimulation to the dermis.
Because it cleans up the skin surface, the improvement effect
can appear quickly, but the recovery period is relatively longer.
Non-ablative lasers leave the epidermis intact and
deliver heat stimulation only to the dermis.
There is less surface damage, so the burden of recovery is low, but
it takes a little longer for the improvement effect to appear.
Fraxel and CO2 lasers each
represent non-ablative and ablative treatments, respectively.
Characteristics of Fraxel Laser
Fraxel is a fractional non-ablative laser that
does not treat the entire skin at once but
stimulates by dividing small areas of thermal damage into multiple spots.
The stimulated area promotes collagen production through the natural healing process, and
surrounding normal tissue helps recovery, minimizing skin damage.
Thanks to this, the burden of recovery is low, and
treatment can be performed while maintaining daily life.
It is mainly used for pore improvement, fine wrinkles, skin texture refinement,
and shallow acne scars.
During consultation,Fraxel is often recommended first to those who
have difficulty securing sufficient recovery time due to daily work or studies.Characteristics of CO2 Laser
CO2 laser is a representative ablative laser.
It directly removes the skin surface and delivers
heat stimulation to the dermis to induce collagen regeneration.
Because of this, it is effective in improving deep scars and bumps, and
noticeable changes can be expected with just one treatment.
However, because it removes the skin surface,
the recovery period is longer than with Fraxel, and
redness may persist for a certain period after the procedure, depending on the individual.
It is best to secure enough time before important events and
plan the procedure.
Treatment Selection Guide by Skin ConcernConsider Fraxel first if you are
a working professional or student who has difficulty with a long recovery period,
someone whose main goal is to improve pores and skin texture,
someone who wants to gradually improve the overall texture of the skin,
or someone who has shallow acne scars.
Consider CO2 laser first if you are
concerned about deep and distinct scars or skin bumps,
someone who can secure sufficient recovery time,
if the purpose is to remove specific lesions such as moles or warts,
or someone who expects a definite change with one treatment.
The two treatments can be performed in stages in combination,
and it is safe to determine the order and interval after checking the skin condition.
Precautions Before and After Treatment
Common precautions include avoiding saunas for about a week after the procedure,
strenuous exercise, and alcohol consumption.
Use sunscreen carefully when going out, and
do not pick or irritate the treated area with your hands.
If you are pregnant or breastfeeding,
be sure to consult with a healthcare provider before the procedure.
After CO2 laser treatment, scabs or oozing may occur during the recovery period,
and it is best not to remove them arbitrarily.
Sunscreen and moisturizing should be thoroughly managed to prevent pigmentation.
It is best to schedule the procedure with sufficient time before important events.
Frequently Asked Questions (FAQ)
Q. Which is better, Fraxel or CO2 laser?
It is difficult to determine an absolutely superior treatment because
the appropriate treatment varies depending on skin condition, concerns, and possible recovery time.
Q. How many Fraxel treatments are needed to see results?
Usually, gradual changes can be expected with repeated treatments of 3 to 5 sessions,
and a treatment interval of about 4 to 6 weeks is recommended.
Q. What is the downtime for CO2 laser?
It depends on individual skin condition and the extent of the procedure, but
it is generally best to plan with a margin of 1 to 2 weeks or more.
Q. What treatment is best if I am concerned about both pores and acne scars?
Fraxel is suitable for surface pores and shallow scars,
and CO2 laser or combination treatment is suitable for deep scars.
Q. Can I receive both treatments together?
Staged combination is possible depending on the skin condition, but
it is safe to determine the order and interval through consultation as irritation may increase.
Fraxel and CO2 lasers have the same goal but different approaches and recovery speeds.
The important thing is not which treatment is better, but
the choice that suits your current skin condition, concerns, and lifestyle.
