We choose equipment
to match the depth of your concern
DM Dermatology in Apgujeong has 18 devices that use radiofrequency, ultrasound, laser, and light.
DM Dermatology Equipment
We choose a device by your skin condition, not by its name
Skin concerns form at different depths. Melasma and blemishes sit in the outer layer of the skin, while red blood vessels lie below it in the dermis. Sagging is related to changes in the dermis and in the fascia layer (SMAS) beneath it. Each device differs in the type of energy, the depth it reaches, and what it targets. That is why the right device depends on the concern.
First, a board-certified dermatologist examines the cause and depth of your concern, and your skin's thickness and sensitivity. Then the device, intensity, and number of sessions are chosen. Even for the same concern, the right device can differ from person to person.

ENERGY · DEPTH
Each type of energy reaches
a different depth
Lasers and light are absorbed by different targets depending on their wavelength. When a colored target such as melanin (pigment) or hemoglobin in the blood absorbs light, heat forms at that spot. In general, the longer the wavelength, the deeper it goes.
Radiofrequency warms the dermis with the heat created as electric current passes through tissue. Focused ultrasound gathers energy at one point, like a magnifying glass, and creates small heat points at set depths in the skin. The skin care devices (Triple LDM · Aqua Peel · Qrity) are used to cleanse the skin surface and pores and to replenish moisture.
- 1
Epidermal pigment Melanin built up in the outer layer of the skin shows as melasma, freckles, and blemishes. The 532 Laser, Laser Toning (1064nm), and Cell-toning (420~800nm light) target this pigment.
- 2
Capillaries When fine blood vessels in the upper dermis widen, the face looks red. QuadroStar and DermaV target these vessels with wavelengths absorbed by hemoglobin in the blood.
- 3
Hair follicles · Sebaceous glands Clarity targets hair follicles with 755·1064nm lasers absorbed by the dark pigment in hair (hair removal). Capri's 1,450nm laser warms the upper dermis, where the sebaceous glands next to the hair follicles are.
- 4
Dermis The layer where collagen and elastic fibers are found. Heat reaches this layer in different ways: Thermage FLX and XERF use radiofrequency, Accent Prime uses radiofrequency and ultrasound, Potenza uses radiofrequency from needle tips, Fraxel uses fine columns of laser light, and Tixel uses the heat of a heated tip.
- 5
Fascia layer (SMAS) A thin layer that covers the facial muscles. Ulthera and Shurink focus ultrasound at set depths such as 1.5·3.0·4.5mm, and the 4.5mm depth targets the area near this layer.

PROCESS
How device
treatments work
Whatever the device, the steps from the exam to aftercare guidance are the same.
step 01
Skin diagnosis · Consultation
A board-certified dermatologist checks the skin thickness, the depth of pigment and blood vessels, and the sensitivity of the area of concern. We also ask about your medications, pregnancy, implanted medical devices, and past treatments.
step 02
Choosing the device and plan
We choose a device suited to your concern and skin condition, and set the intensity, number of sessions, and interval. When several devices are combined, we also set the order and spacing.
step 03
Treatment
Makeup and sebum are removed by cleansing. Numbing cream is applied if needed, and laser and light treatments are done while you wear protective eyewear.
step 04
Soothing and aftercare guidance
After treatment, we calm the heat and redness. You go home after we explain sun protection and when you can start cleansing and wearing makeup again.

Caution
Precautions
after device treatment
Until the redness and warmth settle, limit heat, UV exposure, and irritation.
- 01Sun protection
Apply sunscreen of SPF 30 or higher 15 min before going out, and reapply every 2 hours. For at least 4 weeks, limit long outdoor activities at midday, and wear a hat or use a sunbrella.
- 02Heat · Sauna · Exercise
For the 2–3 days while redness and warmth remain, avoid saunas, jjimjilbang (Korean bathhouses), hot baths, and exercise that makes you sweat a lot. After Fraxel, Potenza, or Tixel, avoid them for 1 week.
- 03Cleansing
On the day of treatment, wash gently with lukewarm water and do not rub. After Fraxel, Potenza, or Tixel, use a mild cleanser from the next day.
- 04Exfoliation · Retinol
For 1 week, do not use scrubs, peeling products, retinol, or exfoliating ingredients such as AHA and BHA. Let scabs and flaking skin fall off on their own.
- 05Moisturizing
Apply a mild, fragrance-free moisturizer 2–3 times a day. Reapply more often if your skin feels dry or tight.
- 06Contact us about unusual symptoms
If you have blisters, oozing, pain or redness that keeps getting worse, skin that turns white, or thick dark scabs, contact the clinic right away.
- Common reactions are redness, warmth, swelling, and stinging. After toning and skin care devices, they usually settle within a few hours. After Fraxel, Potenza, or Tixel, they usually settle within 3–7 days.
- After Fraxel, Potenza, Tixel, or spot treatment with the 532 Laser, small scabs or flaking may form and last about 1 week. Picking them off can leave hyperpigmentation or scars.
- Hyperpigmentation (darkening of the skin) may occur after treatment. It is more likely if you have darker skin, have recently tanned, or are exposed to UV light after treatment. Rarely, many toning sessions at short intervals can cause patchy loss of color.
- After a vascular laser, purple spots or bruising may appear and last 1–2 weeks.
- After focused ultrasound such as Ulthera or Shurink, tenderness when pressed may last a few weeks. Bruising, raised marks, and temporary tingling or numbness may occur. Rarely, facial muscles may become weak for a short time.
- Rarely, blisters, burns, or scars may occur. After treatment, acne or tiny bumps may appear for a short time, or blisters around the lips (herpes) may come back.
- We do not treat, or we postpone treatment, in these cases: if you are pregnant, if the treatment area has an infection, a wound, or active herpes, or if you have recently become heavily tanned.
- If you have an implanted electronic device such as a pacemaker or defibrillator, we do not use monopolar radiofrequency devices such as Thermage FLX. Other devices also need to be checked, so please be sure to tell us in advance.
- Please be sure to tell us during your consultation if: you take medication that makes you sensitive to light, such as some antibiotics; you take or have recently taken isotretinoin (an acne medication); you tend to form large scars, such as keloids; you are breastfeeding; you have fillers, threads, or metal implants in the treatment area; you have tattoos, including eyebrow or eyeliner tattoos; or you have had hyperpigmentation after a past treatment.
※ Treatment results, recovery time, and the degree of side effects vary from person to person.
DM DOCTOR
We look at your skin first,
then choose the right device
At DM Dermatology, patients are seen by our medical director, a board-certified dermatologist. We first find out which layer of the skin your concern comes from, then decide with you whether a device is needed and which one suits you.

FAQ
01Is a dermatology clinic with more devices better?
Having many devices means there are more ways of working to choose from. Results depend less on the number of devices than on an accurate diagnosis, the choice of device, and adjustment of intensity. At DM Dermatology, a board-certified dermatologist examines you, then chooses the device that suits your concern.
02What is the difference between Ulthera and Shurink?
Both devices focus ultrasound (HIFU) at set depths in the skin to create small heat points. Ulthera lets the doctor see the layers under the skin on an ultrasound image during treatment. Shurink is made by the Korean company Classys and uses interchangeable cartridges for each depth. Neither device can be called better than the other; we choose based on skin thickness, the degree of sagging, and sensitivity to pain.
03What is the difference between Thermage and XERF?
Both devices deliver heat to the dermis with monopolar radiofrequency. Thermage FLX uses a single frequency of 6.78MHz, while XERF uses two frequencies, 6.78MHz and 2MHz. XERF is designed to combine the two frequencies to choose how deep the heat reaches. We choose the device based on skin thickness and the area of concern.
04How are Laser Toning, the 532 Laser, and Cell-toning different?
Laser Toning applies a 1064nm laser evenly over the whole face at low energy. The 532 Laser has a short wavelength and is used to target freckles and blemishes in the shallow layers of the skin, spot by spot. Cell-toning uses broad-spectrum light of 420~800nm. Depending on the type and depth of the pigment, one is used alone or they are combined.
05Do device treatments hurt a lot?
Each device feels different. Toning and skin care devices feel like a slight sting or warmth, so they are usually done without numbing. Fraxel, Potenza, Tixel, and lifting devices are often used after numbing cream has been on for 30–60 min. If it hurts during treatment, tell us right away. We will adjust the intensity.
06Can I have treatments with several devices on the same day?
If you have several concerns, two or more devices are sometimes used on the same day. However, when heat overlaps in the skin, the risk of redness and hyperpigmentation can rise, so we adjust the order and intensity. Whether to combine them on the same day or space them out is decided after an examination.
07When can I wear makeup after a device treatment?
After toning, skin care devices, and radiofrequency or ultrasound lifting, you can usually wear makeup the same day. After treatments that leave small scabs, such as Fraxel, Potenza, and Tixel, light makeup from the next day is common. Do not rub areas with scabs.
08What equipment does DM Dermatology in Apgujeong have?
DM Dermatology, near Apgujeong Station Exit 5, has 18 devices. For lifting: Thermage FLX, XERF, Accent Prime, Ulthera, and Shurink. For scars and pores: Potenza, Fraxel, and Tixel.
