Caring for your skin
with ultrasound at multiple frequencies:
Triple LDM
Triple LDM is DM Dermatology's ultrasound care that delivers ultrasound at multiple frequencies to the skin, switching between them at short intervals.

Triple LDM
Aesthetic · Triple LDM
LDM is an ultrasound care device made by Wellcomet in Germany. The name stands for ‘Local Dynamic Micro-massage.’ ‘Triple’ means that it alternates between ultrasound at three frequencies.
During care, ultrasound gel is applied to the face, and the handpiece is moved slowly over the skin. No needles are used, and the skin is not shaved off. That is why it is used for hydrating and calming care for dry or sensitive skin, calming care after other treatments, and supportive care for acne-prone skin.
If you have many pus-filled pimples or a skin disease is suspected, medical treatment comes before care. At DM Dermatology, we check your skin first. Then we decide whether LDM suits you and whether you also need other treatments or medical care.

CHECK
If you have these
skin concerns

- Check01
My skin feels tight soon after washing — even with moisturizer, it turns dry and flaky by afternoon.
- Check02
My face flushes and burns easily — when the temperature changes or I switch cosmetics, my cheeks turn red and sting.
- Check03
Redness and swelling after treatments bother me — after laser or injection treatments, I look for care that calms sensitized skin.
- Check04
Small breakouts appear often — I wonder what care I can get alongside my acne treatment.
- Check05
I'm looking for low-irritation care — needles or peels feel like too much, so I want care that does not shave off the skin.
HOW IT WORKS
Ultrasound at multiple frequencies,
delivered in turn
Ultrasound is a very fast vibration that the ear cannot hear. Frequency is the number of vibrations per second. Ultrasound used in skin care vibrates more than a million times per second.
The higher the frequency, the more the ultrasound is absorbed in shallow skin layers; the lower the frequency, the more it is absorbed in deeper layers. So a single frequency mainly reaches one depth.
Triple LDM delivers three frequencies, switching between them every 1–10 thousandths of a second. The manufacturer explains that this lets cells in both shallow and deep layers respond to multiple frequencies together. It named this method ‘dynamic micro-massage.’
Ultrasound does not travel well through air. So gel is applied between the skin and the handpiece to fill the gap. The handpiece glides over the gel without pressing hard. It works differently from lifting devices that focus ultrasound on a single point inside the skin to create heat.

- 1
Ultrasound gel A clear gel that removes air between the handpiece and the skin so ultrasound can pass into the skin.
- 2
High frequency Ultrasound with closely spaced waves. It passes through the epidermis and is mostly absorbed in the shallow dermis.
- 3
Low frequency Ultrasound with widely spaced waves. It reaches deeper layers. The three frequencies alternate at very short intervals.
- 4
Dermis The layer below the epidermis where collagen and elastic fibers support the skin.
- 5
Subcutaneous fat The fat layer below the dermis.
CARE FOR
Three uses
of Triple LDM
In this care, a handpiece is moved over gel-covered skin. No needles are used and the skin is not shaved off, so it is relatively easy to return to daily life after care. Depending on your skin, we plan one of the uses below or combine them.
- HydrateHydrating care for dry skinCombined with moisturizing care, it may help smooth dry, tight skin.
- CalmCalming red, sensitive skinIt may help calm skin that flushes easily or skin sensitized after laser or injection treatments.
- ClearSupportive care for breakout-prone skinFor acne-prone skin, it is planned as supportive care alongside medical treatment. Pus-filled pimples are treated medically first.
COMPARE
Triple LDM and HIFU lifting:
different methods
Both use ultrasound, but they differ in how it is delivered and what it is for.
The two methods do not replace each other. Which method suits you is decided based on your skin and concerns.

Caution
Aftercare and
reactions to know about
On the day of care, it is better not to add heat or irritation to your skin.
- 01Wash gently
Wash with lukewarm water and a mild cleanser. Pat dry with a towel instead of rubbing.
- 02Moisturize well
On the night of care, apply a gentle moisturizer. If your skin feels tight, you can apply more.
- 03Avoid heat on the day
On the day of care, skip saunas, hot spas, exercise that makes you sweat a lot, and alcohol.
- 04Limit sun exposure
If you had the LED step, limit sun exposure for two days. Apply sunscreen before going out, and wear a hat or use a sunbrella too.
- 05Pause irritating ingredients for a while
While redness remains, pause scrubs, peeling products, and retinol.
- 06Don't squeeze breakouts
Do not squeeze breakouts that appear after care. Show them to our medical staff at your next visit.
- Right after care, you may have redness, a warm feeling, or stinging or tickling. These usually settle in about 1 hour and may last 1–2 days for sensitive skin. How red the skin gets and how long it lasts varies from person to person.
- For acne-prone skin, breakouts may increase for a short time during the first few sessions. If breakouts get worse or spread, let our clinic know.
- Rarely, the ultrasound gel or mask ingredients may cause contact dermatitis, such as itching, a red rash, or hives. If you have had an allergic reaction to cosmetics or gel, please tell us in advance.
- Be sure to tell us before care if you have an implanted electronic device such as a pacemaker or defibrillator, or metal implants or dental prostheses in the face.
- If you have a skin infection or open wound in the treatment area, or a cold sore (herpes simplex) on the lips, care is postponed or that area is avoided.
- Please tell us if you have cancer (a malignant tumor) in the treatment area or are being treated for it. Ultrasound care is not done on that area. Please also tell us in advance if any area has reduced sensation.
- Ultrasound is not applied directly over the eyes (eyeballs).
- Please tell us in advance if you are pregnant or might be. Our medical staff will decide whether to go ahead with care.
- If you have recently had filler, a thread lift, Botox (botulinum toxin), or laser treatment, please tell us the dates. Our medical staff will decide the timing and order of care.
- If your care includes the LED step, please tell us in advance if you take medication that makes you sensitive to light (for example, isotretinoin or lithium) or have had skin cancer.
Even with the same care, how it feels and the results depend on your skin condition, lifestyle, and home care, and vary from person to person.

FAQ
01What does LDM do?
LDM is skin care that delivers ultrasound at multiple frequencies in turn. It is used for hydrating (dewy-glow) care for dry, dull skin, calming care for red, sensitive skin, and supportive care for acne-prone skin. How much changes, and when you notice it, varies from person to person.
02Does LDM care hurt?
LDM care is done without numbing. You will mostly feel cool gel and the handpiece gliding over your skin, and some areas may feel warm or tickly. If it is uncomfortable, tell us right away, and our medical staff will lower the strength. How much you feel varies from person to person.
03How long does Triple LDM care take?
The ultrasound step takes about 12 min. Cleansing and the finishing steps (LED and a modeling mask, depending on the plan) take extra time. Because it is done without numbing, there is no time spent applying numbing cream and waiting. We tell you the total care time after a consultation.
04Can I wear makeup right after LDM?
You can usually wash your face and wear makeup right after care. Redness usually settles in about 1 hour, and in sensitive skin it may last 1–2 days. On the day of care, skip saunas, hot spas, intense exercise, and alcohol. If you had the LED step, limit sun exposure for two days and apply sunscreen before going out.
05How often, and how many times, should I get LDM?
Generally, sessions are once a week at first, and sometimes up to twice a week during intensive care. Usually 5–10 sessions are done in a row. Once your skin is stable, the interval is extended to once every 2–4 weeks. The actual schedule is set based on your skin.
06Can I get LDM after laser or injection treatments?
LDM is also used as care to calm skin that has become sensitive after laser or injection treatments. It can also be planned together with other care and treatments such as Calming Care, Aqua Peel Care, and Aqua Glow Injection. Whether to have it the same day or a few days later depends on the type of treatment and your skin. If you tell us your recent treatments and their dates, our medical staff will check your skin and set the order and intervals after a consultation.
07Can I get LDM if I have acne?
For skin with some small breakouts, LDM can be planned as supportive care alongside medical treatment. If you have many pus-filled pimples or deep, painful lumps, medical treatment comes first. Breakouts may increase for a short time during the first few sessions, so let us know if your skin changes.
08Is LDM ‘water drop lifting’ a lifting treatment?
‘Water drop lifting’ is a nickname for LDM in Korea. LDM works differently from HIFU lifting (Ulthera, Shurink), which focuses ultrasound on a single point inside the skin to create heat. If sagging skin is your main concern, we discuss lifting treatments separately.
09Can LDM brighten my skin?
LDM is not a device that targets melanin pigment the way lasers do. For concerns caused by pigment, such as melasma and dark spots, we plan pigment treatments after an examination. If your skin looks dull because it is dry, LDM can be planned together with moisturizing care.
