Rinsing out pores
with a fine water jet:
Premium Qrity
Premium Qrity is DM Dermatology's care for acne-prone skin that uses the Qrity device to rinse sebum and dead-skin debris out of pores.

Premium Qrity
Aesthetic · Premium Qrity
Qrity is a skin care device made by a Korean medical device company. From the tip of its handpiece, it sprays a fine jet of water about 0.06 mm wide onto the skin and immediately draws the water back in. This drawing-in is called suction. The aim is to rinse sebum and debris from pore openings with water and suction.
Qrity does not use laser or light. It also works differently from extraction, where comedones are pressed out one by one by hand or with a tool.
If you have many red, pus-filled pimples or deep, painful lumps, medical treatment comes before cleansing care. At DM Dermatology, we check your acne first. Then we decide whether Qrity suits you and whether you also need medical treatment such as medication.

CHECK
If you have these
pore concerns
The dark dots on my nose and chin fill back in a few days after I squeeze them
By afternoon my forehead and nose get shiny, and my makeup settles into my pores and lifts
I can feel tiny bumps on my forehead and cheeks, and my skin texture is uneven
Squeezing has left marks before, so I'm looking for a way to clear pores without touching them
I want to keep my pores clean while I'm using acne medication
Deep, painful acne is checked first in a medical examination, before any care.
HOW IT WORKS
Why pores clog and
what the water jet does
At the pore opening, dead skin cells and sebum clump together into a small plug. This plug is called a comedone. A comedone with an open top is a blackhead. The black color of a blackhead is not dirt; it is the pore contents changing color on contact with air. That is why hard scrubbing will not wipe it away and only irritates the skin.
Qrity's suction handpiece sprays a fine water jet and draws the water straight back in. The manufacturer explains that the jet reaches the pore opening to rinse away sebum, and suction then draws it out.
Sebaceous glands keep making sebum. So even a pore that has been cleared fills again over time. Qrity is not a one-time treatment. We continue it at regular intervals and plan home care and medical treatment along with it.

- 1
Water jet A fine stream of water sprayed from the tip of the handpiece.
- 2
Comedone A plug of dead skin cells and sebum that blocks the pore opening. If the top is open, it looks like a blackhead.
- 3
Sebaceous gland A gland beside the hair follicle that makes sebum. Cleansing care does not remove this gland.
- 4
Epidermis The outermost layer of the skin. This is where the water jet lands.
- 5
Hair follicle The pocket a hair grows from. Its opening on the skin surface is the pore.
HOW QRITY WORKS
Three functions
of the Qrity device
Qrity has two handpieces. One is the suction handpiece, which sprays a water jet and draws it back in; the other is an ultrasound handpiece. The spray strength and suction strength can be adjusted separately, so sensitive areas are treated gently.
- SprayWater jet spraySprays a stream finer than a pore to wet and rinse the pore opening.
- VacuumSuctionDraws the sprayed water straight back in, pulling out loosened sebum and dead-skin debris with it.
- UltrasoundUltrasoundThe second handpiece vibrates at 3 MHz and 10 MHz. You may feel warmth where it touches the skin.
COMPARE
Extraction · Aqua Peel · Qrity:
different methods
These are three ways to clear pores. They do not replace one another; we choose one or combine them depending on your acne.
| Comedone extraction | Aqua Peel | Qrity | |
|---|---|---|---|
| Method | Comedones are pressed out one by one with a sterilized tool. | A tip is placed on the skin, and care solution flows out while suction draws it in. | A fine water jet is sprayed, and the water is drawn back in. |
| What touches the skin | Tool tip | Tip and care solution | Water jet and suction tip (the ultrasound handpiece is separate) |
| Area covered | Each comedone | Whole face | Whole face |
| After care | Redness or small scabs may form where pressure was applied. | Mild redness may occur. | Faint redness may remain where suction was applied. |
With Aqua Peel and Qrity, which use suction, small red dots can rarely appear where suction was applied. Which method to use, and in what order, is decided after looking at your acne.

PROCESS
Premium Qrity
treatment steps
Below is the general flow. We explain the actual plan after an examination.
Examination · skin check
We look at what kind of acne you have and how red and swollen it is. We also check oral or topical medications, recent laser treatments or peels, and any history of cold sores (herpes) on the lips. If you have many pus-filled pimples, we may recommend medical treatment before care.

Cleansing
We remove makeup and surface oil.

Qrity water jet · suction
The suction handpiece passes over the face area by area. We adjust the spray and suction strength while watching how your skin responds. Depending on your skin, the ultrasound handpiece may be used next.

Soothing · finish
We finish with a step that calms sensitized skin. Sunscreen is applied last.

Home care guidance
We explain what to do at home, such as when to wash your face, moisturizing, sun protection, and keeping your hands off your skin.

Caution
Aftercare and
reactions to know about
For a day or two after care, your skin may be more sensitive than usual.
- 01Wash your face after 1–2 hours
On the day of care, wash gently with lukewarm water and a mild cleanser. Pat dry with a towel instead of rubbing.
- 02Light moisturizing
If your skin feels tight, apply a light moisturizer. Choose a product labeled as not clogging pores (non-comedogenic).
- 03Protect from the sun for a few days
For a few days after care, skin is more sensitive to sunlight. Apply sunscreen before going out, and wear a hat or use a sunbrella too.
- 04Leave remaining comedones alone
Do not squeeze blackheads that remain after care, by hand or with a tool. Talk to our medical staff about them at your next session or visit.
- 05Pause irritating ingredients for a while
It is better to pause scrubs, peeling gels, and retinol products for a few days right after care. Do not stop prescribed acne medication; ask our medical staff first.
- Right after care, you may have redness, stinging, itching, or warmth. These usually settle within a day. How red the skin gets and how long it lasts varies from person to person.
- Small red dots (petechiae) may appear where suction was applied, and bruising may rarely occur. If you have a condition that makes bleeding hard to stop, or take blood-thinning medication, please tell us in advance.
- Dryness, flaking, or temporary breakouts may occur for a few days after care.
- If you have had cold sores (herpes simplex) on the lips, the stimulation of care may bring them back. If you currently have a blister, a skin infection, an open wound, or sunburn, care is postponed.
- Be sure to tell us before care if your skin flushes easily, as with rosacea, or if you scar easily or have had keloids.
- Please tell us if you are taking an oral acne medication such as isotretinoin or stopped it within the past 6 months. Your skin may be dry and fragile, so the same strength can irritate it more. Our medical staff will decide the timing and strength of care.
- Deep, painful acne such as nodules and cysts is not resolved by cleansing care. This kind of acne is treated medically.
Even with the same care, results and how it feels depend on your skin condition, amount of sebum, lifestyle, and home care, and vary from person to person.

FAQ
01Is Qrity a laser?
No. According to the manufacturer's materials, Qrity has two handpieces: a water jet/suction handpiece and an ultrasound handpiece. No part of it emits laser or light. You can think of it as cleansing care that rinses pores with water.
02Does Qrity hurt?
Qrity care is usually done without numbing. You may feel stinging or tickling when the water jet touches the skin, and a pulling sensation during suction. If it feels strong, tell us right away, and our medical staff will lower the water jet strength and the suction strength. How much you feel varies from person to person.
03How long does Qrity care take?
Qrity care usually takes about 30–40 min. Consultation and cleansing take extra time. Because it is usually done without numbing, there is no time spent applying numbing cream and waiting. We tell you the actual care plan and time after an examination.
04Can I wear makeup on the day of Qrity?
You can usually wash your face and wear makeup 1–2 hours after care. Redness usually settles within 1 day, and in sensitive skin it may last 1–2 days. On the day of care, skip saunas, hot spas, and intense exercise. If redness remains, keep makeup light that day.
05How often should I get Qrity?
Generally, 3–6 sessions are planned. You start with sessions every 2 weeks, then space them out to every 3–4 weeks once your skin is stable. Having it too often can make your skin sensitive. We tell you the actual schedule after an examination, based on your acne and any medical treatment you receive alongside it.
06Can I get Qrity together with other treatments?
Qrity, comedone extraction, and Aqua Peel do not replace one another; they are chosen or used together depending on your acne. If you have many red, swollen pimples, you can look into medical treatment and DM Inflamed Acne care; if enlarged pores concern you, Triple Pore Care. If you have had a laser or peel recently, please tell us at your consultation. Whether to combine them, and in what order, is decided after an examination, based on your skin.
07How is Qrity different from Aqua Peel?
Both are cleansing care that uses water and suction. Aqua Peel places a tip on the skin and draws in care solution as it flows out, while Qrity sprays a fine water jet and then draws it back in. Qrity also has a separate ultrasound handpiece. Which one suits you is decided based on your skin condition and how sensitive your skin is.
08Will Qrity get rid of my blackheads?
Qrity may help rinse away sebum and dead skin cells built up at pore openings. However, sebaceous glands keep making sebum, so even pores that have been squeezed can fill up again within 30 days. That is why we do care at regular intervals and, if needed, add a topical medication that helps keep pores from clogging.
09Are all the dark dots on my nose blackheads?
Not necessarily. The white or yellowish dots packed closely on the nose are often sebaceous filaments. Sebaceous filaments are a normal structure in which pores are filled with sebum, so it is natural for them to fill again after being cleared. Squeezing them hard can irritate the skin around the pores.
10Can I get Qrity if I have inflamed acne?
If only a few small red pimples are mixed in, our medical staff can lower the strength or avoid those areas. If you have many pus-filled pimples or deep, painful nodules or cysts, medical treatment comes first. The doctor examines you and decides whether medication or injection treatment is needed.
11Can Qrity get rid of Demodex mites?
Demodex mites are tiny mites that live in pores, and most adults have them. Skin inflammation caused by an overgrowth of Demodex is confirmed by examination and treated with topical or oral medication. Cleansing care such as Qrity does not replace this treatment.
