Hello.
I am Director Hwang Jeong-bo of Cleor Clinic Gangnam.
Have you ever looked at your phone after taking a photo...
...and noticed that only your face looks particularly red?
It's not a burn, and it's not a makeup mistake,
but your face always looks a shade redder.
Even after applying sunscreen and soothing cosmetics,
you don't feel any fundamental change.
Frequent facial flushing...
...starts not on the skin surface, but from the blood vessels beneath it.
It is a place that surface-soothing care cannot reach.
Today, for those looking into Gangnam redness lasers for the first time,
I will speak honestly about vascular laser treatments
that address persistent facial flushing and visible capillaries.
Redness is not just one thing.
Many people say "I want to get rid of my redness" in the consultation room,
but in reality, redness consists of various types that are difficult to group into a single category.
1) Temporary Facial Flushing
This type occurs when you are nervous, drinking alcohol, or in a hot place,
where the face turns red briefly and then subsides.
It is a change closer to an autonomic nervous system response.
2) Chronic Facial Flushing
This type involves the face appearing a shade redder even under normal conditions.
Often, dilated capillaries fail to contract
and remain in a stretched state.
3) Telangiectasia (Visible Capillaries)
This type presents as thin red lines branching out on the skin surface.
It commonly appears on the sides of the nose and cheeks.
4) Post-Inflammatory Erythema (PIE)
These are pinkish marks left where acne has subsided.
Since it is a vascular response rather than pigmentation, it does not fade easily with standard pigment treatments.
5) Rosacea-related Redness
This type involves chronic redness centered around the cheeks and nose.
It is closer to a skin disease category,
requiring professional diagnosis and management.
Often, these five types are mixed together on a single person's face.
Therefore, redness care has limits when using only surface-soothing cosmetics.
This is why people begin looking into Gangnam redness lasers.
Why do capillaries stay dilated and hardened?
Inside the skin, capillaries thinner than a hair
are densely distributed.
Temperature regulation, oxygen supply, and nutrient delivery
are carried out through these vessels.
The problem is repeated irritation.
UV rays, alcohol, spicy food, sudden temperature changes,
stress, incorrect peeling procedures…
When these irritations are repeated, capillaries dilate
and reach a state where they cannot return to their original size.
To use an analogy, it's like an old faucet washer becoming loose,
causing water to leak even when turned off.
Once dilated, blood vessels do not narrow on their own over time.
That is why surface care cannot reach them.
Soothing creams or mists only reduce surface irritation;
they cannot act on the size of the blood vessels themselves.
A method that directly reaches the dilated vessels is needed.
Gangnam Redness Laser: What is Derma V?
The device used at Cleor Clinic Gangnam for redness treatment
is Derma V.
It is a Long Pulse laser device specialized for vascular and pigmented lesions.
It is a medical device cleared by both the Korean MFDS (KFDA) and the US FDA.
Core Technology — Dual Wavelength
The key is that two wavelengths are contained within a single device.
532nm Wavelength (KTP)
It acts on surface and intermediate-depth vessels and pigments.
Since it is a wavelength well-absorbed by hemoglobin,
it reacts selectively to dilated capillaries or visible blood vessels.
It is also used for pigmented lesions such as melasma, blemishes, and freckles.
1064nm Wavelength (Nd:YAG)
This wavelength reaches deep into the dermal layer of the skin.
It delivers stimulation to deep-seated vessels and collagen/elastin fibers,
assisting in the improvement of skin elasticity and fine lines.
What it means to have both wavelengths
It means that surface vascular redness and the dermal elasticity environment
can be addressed simultaneously in a single treatment.
It is like treating the same area at two different depths.
Other Strengths of Gangnam Redness Laser
Beyond the dual wavelength, Derma V has more technical advantages.
1) Multi-Pulse Fractional Irradiation
Instead of firing strong energy all at once,
it delivers the same amount of energy divided into multiple pulses.
It's like lightly pressing a stamp multiple times
rather than pressing it hard once in the same spot.
This prevents the skin surface from overheating
while ensuring energy is delivered stably to the depth of the vessels.
2) Real-time Temperature Monitoring
It is equipped with a function that measures and displays the skin surface temperature in real-time during the procedure.
If overheating is suspected, the output can be adjusted immediately.
3) Cryogen Gas Cooling
The moment the laser is fired, cryogen gas cools the skin surface.
This reduces the burden of pain while
acting as a protective mechanism to prevent epidermal damage.
In most cases, the procedure can be performed without numbing cream.
4) Various Indications with One Device
Facial flushing and visible capillaries (Vascular)
Acne marks PIE (Vascular)
Melasma, blemishes, freckles (Pigmented)
Fine lines and loss of elasticity (Regenerative)
It is a multi-platform laser that can address various concerns with one device,
and it is the representative equipment for Gangnam redness lasers.
What changes can be expected?
1) A more refined overall facial tone
By acting selectively on dilated vessels,
many people experience an overall calmer skin tone.
2) Fading of visible capillaries
Thin red lines visible on the surface
can be expected to gradually fade after the treatment.
(They often do not disappear all at once; the degree of change becomes clearer with cumulative treatments.)
3) Changes in acne marks (PIE)
Pinkish marks where acne has subsided
(vascular marks, not pigment) can also be expected to improve.
4) Simultaneous improvement of skin texture and tone
Along with vascular changes, areas treated with the deep 1064nm wavelength
can also show improvements in fine lines and texture.
Changes stabilize more effectively with cumulative treatments rather than a single session.
Usually, 3–5 sessions are recommended, with the frequency adjusted based on individual conditions.
Advantages of Derma V
Vascular and pigment-specialized laser cleared by both Korea and the US
Multi-layer approach from the surface to the dermis with 532nm + 1064nm dual wavelengths
Relatively low skin irritation due to multi-pulse fractional irradiation
Enhanced safety with real-time temperature monitoring and cryogen gas cooling
Can be performed without numbing cream in most cases
Short procedure time and immediate return to daily life
It is difficult for all redness and visible capillaries to disappear in a single treatment.
This type of care requires cumulative treatments,
usually 3–5 sessions are recommended, adjusted according to individual conditions.
If UV exposure and vascular dilation triggers (alcohol, sauna, etc.)
are repeated after the procedure, the effects may diminish quickly, so lifestyle management must be maintained.
Deep rosacea-related redness or chronic inflammatory redness
may have limits with laser alone and may require combination with medication or other care.
We will confirm this during the pre-treatment consultation.
Who do we recommend this to?
Those whose faces look particularly red every time they take a photo
Those who have started to see visible capillaries on the sides of the nose or cheeks
Those whose facial redness does not subside for a long time after a drink or in a hot place
Those with pinkish marks left where acne has subsided
Those who did not feel much change with soothing cosmetics
Those concerned about redness along with pigmentation and fine lines
Cases that must be checked during the pre-treatment consultation
If you are pregnant or breastfeeding
If you have active inflammation or a history of herpes in the treatment area
If you are taking photosensitizing medications
If you have a keloid-prone skin type
If you have been diagnosed with an autoimmune disease
If you have recently had strong UV exposure or a peeling procedure
If you are regularly taking anticoagulants
Since the procedure may not be suitable depending on skin condition and medication history, we will confirm this during the consultation.
Pain and Recovery
As cryogen gas cooling operates simultaneously,
it can be performed without numbing cream in most cases.
Areas with prominent blood vessels may feel a slightly more stinging sensation.
It takes about 10–20 minutes for the entire face.
There may be slight redness and a mild warm sensation immediately after the procedure.
These usually subside within a few hours to a day.
Areas where capillaries were prominent may temporarily darken in color
before fading over several days.
Makeup and return to daily life are possible immediately after the procedure.
However, focusing on soothing the skin on the day of the procedure is beneficial for recovery.
⚠️ Precautions
Due to the nature of redness and vascular care, there are things to be mindful of for a few days.
Avoid irritants that dilate blood vessels
Sun protection
Take a week-long break from irritating cosmetics
Moisturizing and soothing care
When an immediate visit is necessary
If persistent pain, blisters, oozing,
or intense redness lasts for more than a few days,
please visit the clinic immediately for an evaluation.
❓ Frequently Asked Questions
Q. How much change can be seen in one session?
Some people notice changes in light redness or small capillaries after 1–2 sessions.
For deep-seated vascular dilation or PIE marks, the degree of change often becomes more apparent after 3–5 cumulative sessions.
Q. How painful is it?
With cryogen gas cooling, it is at a level that can be performed without numbing cream in most cases.
Areas where blood vessels are concentrated may feel a slightly more stinging sensation.
Q. Is it possible to return to daily life immediately after the procedure?
Makeup and return to daily life are possible immediately after the procedure.
Light redness often subsides within a few hours.
Q. How long do the effects last?
It varies depending on individual skin condition, lifestyle habits (alcohol, UV exposure), and maintenance.
Maintaining lifestyle habits such as sun protection and avoiding irritating foods
will help the effects last longer.
Q. Can it be combined with other treatments?
It is often combined with skin boosters, pigment toning, and lifting procedures.
We will guide you on the sequence and schedule during the consultation.
Q. Do visible capillaries disappear in one session?
The response of visible capillaries varies depending on their thickness and depth.
Thin capillaries may fade in 1–2 sessions,
while thicker vessels require more sessions.
Q. What are the potential side effects?
Temporary redness, heat sensation, mild swelling, and temporary color changes in the treated area may occur.
Rarely, blisters, hyperpigmentation, or hypopigmentation
have been reported, so pre-treatment consultation and post-treatment follow-up are important.
Persistent facial flushing and visible capillaries
start in places that surface care alone cannot reach.
Once dilated, capillaries do not narrow on their own over time,
so a time comes when a treatment that acts directly on the dilated vessels is necessary.
Derma V, used as a Gangnam redness laser,
is a vascular laser cleared by both Korea and the US.
By utilizing both 532nm and 1064nm wavelengths,
it is an option that can address facial tone refinement, capillary care, pigmentation, and elasticity all at once.
We will confirm this during your consultation.
For your information, the Gangnam branch offers not only standalone Derma V treatments
but also packages combined with Redness Mode, Cryo, and Modeling Masks,
and packages combined with Perfect Toning, Regenerative LED, and Sheet Masks.
You can receive guidance on these additional care packages when you visit.
