Agnes
Agnes is a treatment that inserts a fine insulated needle, exposed only at the tip, into the skin and releases radiofrequency heat from the needle tip only to coagulate small targets.

Agnes
Laser · Agnes
The upper part of the needle is covered with a thin film that does not conduct electricity (an insulating coating). The radiofrequency current comes out only through the uncovered tip. So the heat gathers at the depth the tip reaches. The skin surface (epidermis), where the insulated part passes through, receives less heat.
The target differs by concern. Under the eyes, it is fat that has pushed forward; in acne, the sebaceous glands that make sebum; and in syringoma, small bumps made of clustered sweat duct cells.
At DM Dermatology in Apgujeong, we first examine the cause of the puffiness, acne, or bumps before treatment. Under-eye puffiness can be due not only to fat but also to swelling, sagging skin, or a sunken tear trough, and the right method differs by cause. The degree of change and recovery time vary from person to person.

Why depth matters
Under-eye puffiness, acne, small bumps:
each cause sits at a different depth
Under-eye puffiness forms when fat around the eyeball pushes forward. Inflamed acne starts in the sebaceous glands in the dermis, and small bumps under the eyes (syringoma) start from sweat duct cells clustered in the dermis.
That is why Agnes uses a needle chosen to match the depth of the target.
TARGETS
The three targets
of Agnes
All three targets are treated with heat from the needle tip. But the needle length and insertion point differ.

Eye Bag
Under-eye fat
A long needle is inserted toward the bulging fat to deliver heat to the fat and the membrane that holds it. A short needle may also treat the dermis above it. If there is a lot of fat or the skin sags a lot, surgery may be a better fit.
- Orbital fat · Orbital septum

Acne
Inflammatory acne
The needle is inserted into the pore with acne and delivers heat to the sebaceous gland that makes sebum. The insulated part passes through the surface skin, so damage there tends to be small. We plan it together with topical and oral medication care.
- Sebaceous glands

Syringoma
Syringoma
Syringoma is a small benign bump of sweat duct cells clustered in the dermis, common under the eyes and on the upper cheeks. A needle is inserted into each bump to produce heat from within. If there are many, treatment is split over several sessions.
- Sweat duct cell bumps
At DM Dermatology, Agnes is offered in two categories: 'Under-eye' and 'Special areas.' Which targets to treat is decided after an examination.
HOW IT WORKS
How heat comes only
from the needle tip
Radiofrequency is an electric current that changes direction about 1 million times per second. When this current passes through body tissue, heat is produced within the tissue. Instead of placing a device on the skin surface, Agnes sends the current directly into the skin through a needle.
The current comes out only through the needle tip, which has no insulating coating. So the heat gathers in a small area around the tip. At each point, current usually flows for less than 1 second. The heated target tissue coagulates and is gradually cleared during healing.
Needles come in several types with different lengths and insulation lengths. Long needles are used for deep targets such as under-eye fat, and short needles for shallow targets such as sebaceous glands. Choosing a needle that matches the target's depth is the key to this treatment.

- 1
Insulated part A thin film covering the upper part of the needle. No current comes out of this part, so the skin surface receives less heat.
- 2
Needle tip The bare tip of the needle, not covered by the film. Radiofrequency current comes out only here.
- 3
Radiofrequency heat Heat produced in a small area around the needle tip.
- 4
Target tissue Tissue that coagulates when heated. The drawing shows an acne sebaceous gland; depending on the concern, the target is under-eye fat or syringoma.
- 5
Epidermis The outermost layer of the skin. The insulated part passes through this layer, so damage to the surface skin tends to be small.
DEPTH
A different depth for each target
Depending on how deep the target is from the skin surface, the needle length and insulation length change.
- EpidermisAbout 0.03–0.06mm
- Upper dermis · SyringomaSweat duct cell bumps
- Dermis · Sebaceous glandsAbout 0.5–1.5mm
- Muscle · Orbital septumThe membrane that holds under-eye fat
- Orbital fatAbout 2.5–5mm
Where the needle tip produces heatThe epidermis is where the insulated part passes.
- Syringoma · Upper dermis
A short needle is inserted into the bump to heat the sweat duct cells clustered in the dermis. If a bump extends into the deep dermis, it tends to grow back, so we follow its progress.
- Acne · About 0.5–1.5mm
The tip of a short needle inserted into the pore produces heat at the level of the sebaceous gland. About 0.5mm on the skin side is covered by the film.
- Under-eye fat · About 2.5–5mm
A long needle passes through the muscle and membrane around the eye to reach the fat. The exposed tip delivers heat to the fat and the membrane that holds it.
Values are estimates based on facial skin thickness and needle length. Actual depth varies by area and person, and eyelid skin is among the thinnest on the face.
CHECK
If you have these concerns
- Check01
The area under my eyes bulges out — It stays the same even after a good night's sleep, and people often tell me I look tired.
- Check02
Under-eye surgery still feels like too much — I worry about incisions and recovery time, so I want to look into options without incisions first.
- Check03
Red, painful acne keeps coming back — Even with medication, pus-filled acne keeps appearing in the same spots on my chin and cheeks.
- Check04
Excess oil keeps clogging my pores — My face gets shiny by afternoon, and clogged pores turn into acne.
- Check05
Small bumps under my eyes have increased — Several small skin-colored or yellowish bumps are clustered under my eyes and on my upper cheeks.
Whether Agnes suits you is decided after examining the cause of the puffiness, acne, or bumps. Some bumps, such as milia, can look similar to syringoma.
PROCESS
Agnes
treatment process
Below is the general flow. We explain DM Dermatology's steps and timing after an examination.

step 01
Examination · Marking
We check whether under-eye puffiness is due to fat and what kind of acne or bumps you have. We ask about implanted electronic devices such as pacemakers, pregnancy or breastfeeding, and your medications, then mark the treatment points.

step 02
Cleansing · Numbing
Makeup is removed, numbing cream is applied to the treatment area, and we wait 20–30 min. For under-eye fat, a numbing injection may be added.

step 03
Agnes treatment
When the monopolar mode is used, a thin pad that lets the current exit the body is attached. At each marked point, the needle is inserted and radiofrequency is delivered very briefly. If it feels hot or painful, tell us right away.

step 04
Soothing · Cold pack · Going home
The needle points are disinfected and a soothing cream is applied. Under the eyes, a cold pack calms swelling and heat. We tell you when you can start washing your face and wearing makeup, and the next session is usually scheduled 4 weeks later.
RECOVERY
Recovery after treatment
This is the general course for under-eye fat treatment.
- Day of treatment
There are small red dots and warmth at the needle points. The under-eye area swells from the numbing and treatment and may bruise.
- Days 2–3
Swelling may become more noticeable, then begins to settle. Small scabs may form on acne or syringoma spots. Light makeup is OK from the next day.
- 1 week
Under-eye swelling and bruising usually settle in about 1 week. A dark bruise may fade to yellow and last a few more days.
- 1–3 months
As the heated tissue heals, changes appear gradually. Sessions are repeated 4 weeks apart, and progress is checked about 1–3 months after the last session.
The degree of swelling and bruising and the timing of changes vary from person to person. If pain or swelling keeps getting worse, do not wait. Contact the clinic.

Caution
Aftercare and
side effects to know
Until swelling and redness settle, do not add heat or irritation to the skin.

- 01Gentle cold packs
If the under-eye area swells, apply a cold pack wrapped in a towel from time to time for the first 1–2 days. Do not press hard on the eyes.
- 02Leave scabs alone
Leave the small scabs at the needle points until they fall off on their own. Do not pick them with your nails or rub them with a towel.
- 03Avoid heat
While swelling remains, skip saunas, spas, hot baths, alcohol, and exercise that makes you sweat a lot.
- 04Limit sun exposure
For 2 weeks after treatment, avoid long sun exposure. Apply sunscreen before going out and also use a hat or sunbrella.
- 05Pause irritating ingredients
While redness and scabs remain, pause retinol, exfoliants (AHA · BHA), and scrubs. Ask us before stopping any prescribed acne medicine.
- 06Contact us right away about these symptoms
If you get pain or swelling that keeps getting worse, pus, blisters, eye pain, or blurred vision, contact the clinic right away.
- During treatment, even with numbing, you may feel a sting as the needle goes in, or heat and a dull ache as the heat is delivered.
- Swelling and bruising are common after under-eye treatment. They usually settle in about 1 week, but a dark bruise may last longer.
- Redness, small dot-like marks, scabs, itching, tightness, or flaking may appear at the needle points. These usually settle within a few days.
- Post-inflammatory hyperpigmentation (brown marks) or lightening of skin color may occur. It is more likely in darker or tanned skin. It usually fades over several months but may need treatment.
- In rare cases, a bacterial infection may occur, or cold sores (herpes simplex) may come back. If you have had cold sores, please tell us in advance.
- Rare reports include burns, scars, firm lumps under the skin, hollowing from excessive fat loss, and nerve damage. Numbness or increased sensitivity in the treated area may last a few weeks.
- If under-eye puffiness is caused not by fat but by swelling, sagging skin, or a sunken tear trough, the change may be small.
- Acne can come back depending on hormones, sebum production, and lifestyle. Syringoma can also grow back from remaining cells.
- If you have an implanted electronic device such as a pacemaker or defibrillator, be sure to tell us before treatment. This treatment uses electric current, so it may affect the device. Also tell us if you have metal implants or fixation plates near the treatment area.
- If you are pregnant or breastfeeding, please tell us in advance. Treatment is generally postponed.
- If the treatment area has an infection, a wound, or a skin condition such as eczema, or you have a cold sore, treatment is postponed. If you tend to form keloids or thick scars, please tell us in advance.
- Tell us if you bleed easily or take blood thinners (anticoagulants · antiplatelet drugs). Bruising may be larger. Do not stop any medicine on your own; talk to the prescribing doctor first.
- Tell us if you are taking oral acne medicine (isotretinoin) or stopped it within the last 6 months. The doctor decides when to treat.
- Tell us in advance if you have had an allergy to anesthetics (such as lidocaine) or metal (stainless steel).
- Tell us if you have a condition or take medicine that weakens immunity, have uncontrolled diabetes, or are receiving cancer treatment. If you have recently had filler, laser, peeling, or surgery around the eyes, or use a retinoid ointment, tell us along with the dates.
Even with the same treatment, the degree of change, how long swelling and bruising last, and the number of sessions needed vary from person to person.

FAQ
01Does Agnes hurt? How is numbing done?
Numbing cream is applied to the treatment area, and we wait 20–30 min before treatment. For under-eye fat, a numbing injection may be added. Even with numbing, you may feel a sting as the needle goes in, or heat and a dull ache as the heat is delivered; how much varies by area and person. If it is hard to bear, tell us right away during treatment.
02How long does Agnes take?
Treatment time depends on the target. Usually, the under-eye area takes about 30 min, and acne or syringoma 30–60 min. This does not include the 20–30 min for applying numbing cream and waiting. We tell you the total time, including the examination and soothing care, after an examination.
03How much downtime does Agnes have? Can I go back to daily life right away?
Under the eyes, swelling and bruising usually last about 1 week. On acne or syringoma spots, red dots and small scabs often remain for 1–3 days. You can wash your face and wear light makeup from the next day. During the week of swelling, skip saunas, hot packs, alcohol, and intense exercise. Recovery time varies from person to person, so if you have an important event, leave more than 1 week before it when you book.
04How many Agnes sessions do I need, and how far apart?
Sessions are usually 4 weeks apart. Under-eye fat takes 2–3 sessions and acne about 3; for syringoma, more sessions are added after the first one based on the bumps that remain. At each session, we check that swelling and redness have settled before deciding on the next one. The number of sessions depends on the amount of fat and your skin, and we tell you after an examination.
05Can I get Agnes together with other treatments?
For acne, Agnes is planned together with treatment with topical or oral medicine. Treatments you can discuss with us alongside it include DM Inflamed Acne, Potenza, and Scar Treatment. If you have recently had filler, laser, or peel treatments, please tell us along with the dates. Each treatment reaches a different depth and has a different purpose, so whether to combine them or do them on separate days is decided after an examination, based on your skin.
06When do Agnes results show?
Right after treatment, swelling makes it hard to judge the change. As the heated tissue heals, things change gradually over several weeks. That is why we check progress about 1–3 months after the last session. The degree of change varies from person to person.
07How is it different from under-eye fat surgery (repositioning · removal)?
Surgery makes an incision inside the eyelid or below the lashes to remove fat or move it into hollow areas. Agnes uses no incision; it delivers heat from the needle tip to the fat and the membrane that holds it. The right method depends on the amount of fat, skin sagging, and tear trough hollowing. We decide together which method suits you after an examination.
08Will acne stop coming back after Agnes?
Agnes aims to reduce inflammatory acne by delivering heat to the sebaceous glands. However, untreated sebaceous glands remain, and acne is also affected by hormones and lifestyle. So acne can come back. After treatment, continue topical and oral medication care along with cleansing and moisturizing.
09Can Agnes treat syringoma under the eyes?
Syringoma is a small benign bump common under the eyes and on the upper cheeks. Agnes inserts a needle into each bump to produce heat from within, and because the insulated part passes through the surface skin, damage there tends to be small. If there are many, treatment is split over several sessions, and they can grow back. Some bumps, such as milia, look similar, so we tell them apart with an examination first.
