TRIPLE PORES CARE
Cleansing · Sebum control · Fraxel:
a 3-step solution!
Triple Pore Care aims to improve pores with three solutions: cleansing, sebum control, and Fraxel. It is DM Dermatology's 3-step customized program that cares for not only pores but also scars and marks left by acne.

Triple Pores Care
DM Dermatology, Apgujeong · Triple Pore Care
Pores look enlarged for more than one reason. When sebum and dead skin cells fill the pore opening, the opening looks stretched. With age, as the dermis supporting the pores weakens, pores look saggy. Depressed acne scars can also look like pores.
So Triple Pore Care divides the steps by the depth where each cause lies. STEP 01 addresses the pore opening, STEP 02 the sebaceous glands that make sebum, and STEP 03 the dermis around the pores. It is not a one-time treatment, but one that continues over several sessions at intervals.
At DM Dermatology in Apgujeong, we first look at pore shape, sebum amount, acne, and scars before treatment. Skin that reddens easily or has many pus-filled pimples may need medical care first. Downtime (the recovery period before returning to daily life) and your next schedule are also decided at this point.

CONCERN
Worried about pores that show even when covered?
Do pores that show even when covered worry you? Pores that have already enlarged do not shrink easily. DM Dermatology’s Triple Pore Care manages pore concerns with steady care and treatment.
Wide Pores
Wide pores
“My wide pores don't stay covered no matter how much makeup I use.”
On the nose and inner cheeks, where a lot of sebum comes out, pore openings widen and foundation easily settles into the pores.
Uneven Texture
Uneven texture
“My uneven skin texture really bothers me.”
When clogged pores and shallow scars mix, light does not reflect evenly and texture looks rough.
Sensitive Skin
Sensitive skin
“My skin is on the sensitive side.”
For skin that reddens easily, we check first in the examination and adjust the strength and order of each step to suit it.
Stubborn Pores
Stubborn pores
“My pores don't get smaller, no matter how expensive my skincare is.”
Cosmetics stay on the skin surface. The elasticity of the dermis that supports pores is hard to change with topical products alone.
WHY PORES
Why pores look enlarged
A pore is the opening of the follicle where hair grows and the channel through which sebum leaves the skin. So pores themselves cannot be eliminated. What treatment aims to change is how noticeable the pores look.
Dermatology literature names three main causes of enlarged-looking pores: high sebum output, reduced elasticity around the pores, and large hair follicles. Recurring acne, hormones, and sun damage also play a part.
Each cause sits at a different depth. A clogged opening is at the very surface of the skin, sebaceous glands are in the dermis, and the collagen that supports pores runs through the whole dermis. Triple Pore Care treats these three depths in separate steps.

- 1
Pore opening · Comedo A plug of dead skin cells and sebum that blocks the opening is called a comedo. An open comedo looks dark at the tip and is called a blackhead. This is where STEP 01 works.
- 2
Sebaceous gland A grape-cluster-shaped gland attached beside the follicle. It sits in the dermis about 1mm below the skin surface. This is where STEP 02 works.
- 3
Dermal collagen Fibers that support the pores like a net. When they decrease with age and sun damage, pores look saggy.
- 4
Microscopic treatment zone Column-shaped zones made in the Fraxel step by splitting the laser into very fine beams. The skin between the columns stays intact and helps healing.
- 5
Acne scar When inflammation damages the dermis, the healed area sinks and leaves a depressed scar. Round, shallow scars can look like enlarged pores.
SOLUTION
Triple Pore Care's
3-step solution
The three steps address different depths of the skin. They go from the surface inward, one after another.
- Skin surface · Pore openingSTEP 01
- EpidermisOuter skin layer
- Upper dermis · Sebaceous glandsSTEP 02 · About 1mm from the surface
- DermisSTEP 03 · About 2mm in cheek skin
- Subcutaneous fat
Depth the Fraxel beams pass throughFine laser beams pass through the epidermis and create column-shaped zones down into the dermis.
- STEP 01 · Cleansing
Clearing out debris inside the pores
We remove the sebum and dead-skin plugs blocking pore openings and the old dead skin on the surface. This also prepares the surface so the next steps reach the skin evenly.
- STEP 02 · Sebum control
Managing sebum output
This step reduces the activity of the sebaceous glands that make sebum, helping control the overflow of sebum that widens pores. Sebum can increase again over time, so it continues at intervals.
- STEP 03 · Fraxel
Micro-resurfacing that cares for scars, elasticity, and pores together
As the thin, column-shaped heat injuries heal, new collagen is made. The changes that support the pores and fill the base of shallow scars happen slowly over several months.
A diagram for explanation. Actual depth varies by person and area, and the method for each step is decided after an examination.
ADVANTAGE
Key features of Triple Pore Care
- ScarsAcne scar improvementIt aims to soften the depth and edges of shallow depressed scars by promoting collagen remodeling in the dermis. For narrow, deep scars, other methods may also be considered.
- DowntimeRelatively little recovery burdenBecause the laser is split into fine columns and the skin between them is left intact, recovery tends to be easier than with peels that remove the whole skin surface.
- Pores · ElasticityAims to improve both pores and elasticityAs collagen in the dermis around the pores increases, the support for the pores increases too. That is why it aims at both pores and skin elasticity.
- PigmentMay help improve freckles and epidermal pigmentSome of the epidermal pigment where the laser passed comes off with tiny scabs. Melasma can actually darken, so we first tell the pigment types apart with an examination.
The degree of change varies from person to person, depending on the condition of the pores and scars and the number of sessions.

PROCESS
Triple Pore Care
treatment flow
Below is the general flow. We explain the actual plan and order after an examination.
Examination
We look at pore shape, sebum amount, acne, scars, and pigment. We also ask about your medications, recent laser or peeling treatments, and any history of cold sores (herpes).

Cleansing
After makeup is removed, the sebum and dead-skin plugs in pore openings and the old dead skin are cleared.

Sebum control
Care focuses on oily areas: the nose, forehead, and inner cheeks. The method and strength are set based on sebum amount and acne condition.

Fraxel
After numbing cream takes effect, the laser is applied to the chosen treatment area: both cheeks, the nose, or the butterfly zone. You may feel stinging and heat as the laser passes.

Soothing · Sun protection
The session ends with a soothing step that calms heat and redness. Sunscreen is applied before you go home, and we explain what to do at home.

RECOVERY
Recovery after Fraxel
- Day of treatment
There is heat, redness, and stinging. It often feels hot like a sunburn and eases within a few hours. The area under the eyes and the cheeks may swell slightly.
- Days 1–3
Redness and swelling settle. The skin may feel tight and rough, and tiny brown dots start to appear where the laser passed.
- About 1 week
Small brown scabs fall off on their own within 5–7 days. Do not pick them off; leave them alone.
- After 4 weeks
Once we confirm the skin has recovered, the next session is done. The collagen-building changes continue for several months after this.
Recovery speed and the degree of redness vary from person to person, depending on laser strength and skin condition.

Caution
Triple Pore Care
aftercare precautions
For 1–2 weeks after Fraxel, the skin is dry and sensitive to sunlight.

- 01Sun protection
Apply sunscreen before going out and wear a hat or use a sunbrella. For 4 weeks after treatment, do not stay in the sun for long. This helps reduce brown marks (hyperpigmentation).
- 02Leave small scabs alone
Picking or rubbing the scabs that look like brown dots with your nails can leave marks.
- 03Moisturize often
Skin may feel tight and dry. Reapply a gentle, low-fragrance moisturizer several times a day.
- 04Pause irritating ingredients
Do not use retinol, exfoliating ingredients (AHA · BHA), scrubs, or peeling pads for the period our medical staff advises. Ask us before stopping any prescribed medicine.
- 05Hands off your pores
Do not squeeze pores that look dark again with your fingers or tools. Squeezed areas can turn red or become inflamed.
- 06Contact us right away about these symptoms
Contact the clinic if you get blisters, pus, pain that keeps getting worse, or small blisters around the mouth.
- Redness, swelling, and heat may occur. They usually settle within 1–3 days, but redness sometimes lasts a few weeks.
- Small brown scabs, flaking, itching, or tightness may occur.
- Post-inflammatory hyperpigmentation (brown marks) may occur. It is reported relatively often in Asian skin and may appear around 1–2 weeks after treatment. It usually fades over weeks to months but may need treatment.
- Acne may flare up for a while, or tiny white bumps like grains (milia) may form.
- If you have had cold sores, they may come back after treatment. Tell our medical staff before treatment.
- In rare cases, bacterial or fungal infection, long-lasting redness, lightening of skin color, or new scars may occur.
- If you are pregnant or breastfeeding, or have inflammation, a wound, or infection in the treatment area, a recent tan or sunburn, or a tendency to form keloids, or if you are taking or recently stopped oral acne medicine (isotretinoin), or take medicine that makes you sensitive to light, talk to the doctor before treatment. Treatment may be postponed.
- Sebum can increase again over time. Depending on age and sebum amount, pores may become noticeable again.
※ The degree of improvement, downtime, and pain felt depend on skin condition and treatment intensity, and vary from person to person.

POTENZA
Potenza:
RF delivered through fine needles
Potenza sends radiofrequency (RF) energy into the dermis or epidermis, and the heat creates a coagulation effect in skin cells. It aims to improve skin concerns such as acne scars, pores and fine lines. The microneedle depth can be set from 0.5–4.0mm to deliver RF energy to the right skin layer.
- Non-invasive RF
An electrode-type tip touches the skin surface and delivers RF evenly into the skin layers.
- Invasive RF
Fine needles enter the skin and deliver RF energy to the deeper skin layers.
- Recommended for
People concerned about acne scars or chickenpox scars, enlarged pores or fine lines, loss of firmness across the face, or uneven skin texture
Which of the two modes to use, and how deep the needles go, is decided at your consultation after checking your skin.
POTENZA PROCESS
Potenza
treatment process
Redness, swelling and small pinpoint bleeding may occur after treatment. They usually settle within a few days. In rare cases, pigmentation, inflammation or infection may occur, so please contact us right away if anything seems wrong. Results and recovery time vary from person to person.
Contact with the skin
RF energy is sent into the dermis or epidermis, depending on your skin condition.

RF energy is generated
The heat energy is used to induce coagulation and collagen production.

Coagulation zones form
As the skin recovers from the heat, this helps collagen production.

FAQ
01Will pore treatment make my pores smaller?
Pores are channels for sebum, so they do not disappear. Triple Pore Care aims to make pores look less noticeable by clearing clogged openings, controlling sebum, and supporting the dermis around the pores. Collagen changes appear over several months. The degree of change varies from person to person.
02Does Triple Pore Care hurt? How is numbing done?
The STEP 03 Fraxel step is done after numbing cream has been on for 30–60 min. Even with numbing, you may feel stinging and heat as the laser passes, and how much varies from person to person with the area and intensity. For a few hours after treatment, it may feel hot like a sunburn. If it is hard to bear during treatment, tell us right away.
03How long does Triple Pore Care take?
One session usually takes about 1 hour 30 min–2 hours. This includes the three steps (cleansing, sebum control, and Fraxel) and the time for applying numbing cream and waiting. Numbing cream is applied for 30–60 min before the Fraxel step. The time depends on the treatment area and your skin condition, and we tell you after an examination.
04How much downtime does Triple Pore Care have? Can I go back to daily life right away?
Typically, redness and swelling last 1–3 days, and small brown scabs 5–7 days. You can wash your face gently from the evening of the treatment day and wear makeup from the next day. Skip saunas, spas, intense exercise, and alcohol until the redness settles. Do not rub off the scabs; leave them until they fall off on their own. Recovery speed varies from person to person.
05How many Triple Pore Care sessions do I need, and how far apart?
Typically 3–5 sessions in a row, 4 weeks apart. If redness or hyperpigmentation remains, the interval may be extended to 4–6 weeks. Collagen changes appear over several months, so we do not judge after one or two sessions. The wider the pores and the deeper the scars, the more sessions may be needed; the number of sessions and the interval are decided after an examination.
06Can I combine Triple Pore Care with other treatments?
Treatments we can discuss alongside it include Scar Treatment, Potenza, and Premium Qrity. If depressed acne scars are your main concern, we may also discuss Scar Treatment. Skin with many pus-filled pimples or skin that reddens easily may need medical care first. Each treatment reaches a different depth and has a different goal, so whether to combine them and how far apart to schedule them are decided after an examination, based on your skin.
07Can it help pores that look wide because of acne scars?
Round, shallow acne scars can easily look like enlarged pores. The Fraxel step aims to soften the depth of shallow scars by promoting collagen remodeling in the dermis. For narrow, deep scars or scars where the skin is pulled down, other methods may also be considered. If scars are your main concern, please also see the Scar Treatment page.
08How are Fraxel and Potenza different?
Fraxel splits laser light into very fine beams to create column-shaped heat injuries in the skin. Potenza inserts fine needles into the skin and delivers radiofrequency heat from the needle tips. Both aim at collagen remodeling in the dermis, but they differ in how heat is delivered and how depth is controlled. Which treatment suits you, and whether to plan both, is decided based on your pores, scars, and skin type.
09What is Potenza?
Potenza is an RF device. It delivers radiofrequency (RF) energy to the dermis or epidermis, and the heat creates a coagulation effect in skin cells to help improve a range of skin concerns. Microneedle depth can be set from 0.5 to 4.0mm, so treatment can be matched to each skin layer.
10How do Potenza's non-invasive and invasive modes differ?
In the non-invasive mode, an electrode-type tip touches the skin surface and delivers RF evenly. In the invasive mode, fine needles enter the skin and deliver RF energy to the deeper skin layers. The mode is chosen to suit your skin condition.
11Can I go back to daily life right after Potenza?
You may wash your face and shower. It is better to start wearing makeup after the redness settles. Be careful not to rub or scratch the treated area hard.
12Is there anything to be careful about after Potenza?
Please avoid alcohol, smoking, saunas and exercise. Your skin may feel dry, so apply lotion or cream often. For about 48 hours after treatment, avoid going out when UV light is strong. Bruising or swelling may occur; this varies from person to person.
13Will sebum and blackheads come back after treatment?
They can come back. Sebaceous glands keep making sebum, and dead skin cells keep building up. So after treatment, continue gentle cleansing, moisturizing, and sun protection, and we set care intervals based on sebum amount. Avoid squeezing pores with your fingers, as it can cause inflammation and leave marks.
14Can I have only my nose pores treated?
DM Dermatology offers pore treatment by area: both cheeks, the nose, and the butterfly zone. The butterfly zone is the butterfly-shaped area joining the nose and inner cheeks. Which area to treat is decided at the examination, based on where your pores are most noticeable.
