Choosing a PMU Studio: Do Reviews Really Decide?
"I went to the place with 5-star reviews and gorgeous photos — so why do my brows look like this?"
"Every studio that comes up for 'best PMU in Seoul' claims to be number one. Who do I trust?"
Hi, I'm CYAN, lead artist at CYAN PMU in Hongdae, Seoul. After serving as a semi-permanent makeup competition judge, teaching powder brows to clinics in Japan, and performing over 30,000 procedures, one thing is clear: the real markers of a good studio aren't star ratings — they're the things you can't easily see. Here are 6 things to check for yourself, beyond the reviews.
Can reviews really tell you who's good at PMU?
Short answer: reviews and star ratings alone can't. A review shows you whether a result looks pretty, but not the hygiene conditions it came from, whether it still looks natural a year later, or whether it suits your skin. Semi-permanent makeup (PMU) is the work of depositing pigment into the shallow layers of the skin to fill in the shape of brows, lips, or eyeliner. It typically lasts 1–3 years (depending on area and skin), and after the first session you'll usually return at least once for a touch-up around 6–8 weeks later. That's why you should look at the system that stands behind the result, not just a single photo.
Reviews are a display case of "results that went well." You need to see the standards behind the glass.
Hygiene — how far should you look to feel safe?
The first thing to check is hygiene and a single-use policy. PMU involves micro-puncturing the skin with a needle, so when hygiene breaks down, the risk of infection and cross-contamination follows. A good studio uses single-use disposables for everything that touches your skin — needles, cartridges, pigment cups, cotton swabs, razors — and opens a brand-new needle in front of you, right before the procedure. Reusable equipment like the machine and mirror is wrapped in protective film to prevent cross-contamination.
✔ Check that the needle and cartridge are opened fresh in front of you
✔ Ask whether pigment, swabs, and razors are single-use too
✔ See whether the pigment is a product with a verifiable maker, ingredients, and expiry date
A studio that proudly shows you the disposables being opened keeps the unseen parts clean too.
Portfolios — which photos are the real proof?
Many people fall for the "right-after" photo, but right after the procedure the color is at its most intense — so it's the furthest from the color that actually stays. What you really want to see are unedited "healed" photos. PMU heals in three stages (clotting and inflammation → proliferation → maturation): for the first 2–5 days it looks darker, around a week the flaking lifts and it lightens, and after about a month it settles into the healed color. So a studio that can show you the one-month result is proving its skill. Trust sets that follow the same person from before → right after → healed — not photos with color painted on by a filter.
✔ Ask for the "one-month healed" photo, not the right-after shot
✔ Look for before → after → healed sequences of the same person
✔ Check for cases with a skin tone and face shape similar to yours
The proof of skill isn't an edited right-after photo — it's an unedited healed one.

How can you tell a studio gives a thorough consultation?
A good studio asks plenty and explains plenty before it ever picks up a needle. It doesn't just hear the shape you want — it reviews the medications you take (over-the-counter blood thinners like aspirin, vitamin E, and omega-3 increase bleeding, so they're usually paused 5–7 days before; but never stop a prescribed anticoagulant on your own — talk to your prescribing physician first), any history of keloids or allergies, pregnancy or breastfeeding status, and your skin type. The ones worth trusting review your allergy history carefully and are honest that no advance check can fully guarantee safety.
✔ Check that they ask about medications, history, and skin type — not just the shape
✔ See whether they ask about pregnancy, breastfeeding, allergies, and keloids first
✔ Confirm that a consent form covers precautions and possible side effects
A studio that asks plenty and explains plenty is just as careful with the procedure.

Touch-up policy — why must you always check it?
With PMU, the first session and the touch-up are one set. The touch-up fills in the areas that faded 6–8 weeks after the first session to complete the final color, so a studio with a vague touch-up policy deserves a second look. Skin renews on roughly a 28-day cycle, and the second pass should happen after that cycle has turned over and the skin has fully healed, so the color sets in evenly — for brows, usually 6–8 weeks after the first session (weeks 4–6, when the color softens by about 30–40% and stabilizes, are just the settling point — not the touch-up moment). A good studio tells you from the very start whether a touch-up is included in the first price, and what the cost is once that window passes.
✔ Confirm in advance whether one touch-up is included in the first price
✔ Check that they keep to the right touch-up window (about 6–8 weeks for brows)
✔ Make sure the cost after the window is stated clearly in writing
A studio that's transparent about its touch-up policy from the start stands behind you to the end.

An artist's experience — how do you judge it?
Experience is less about "how many years" and more about how many different skin types they've worked with. The same design holds differently on oily, dry, and sensitive skin. For context, in Korea a national license for PMU artists (under the proposed tattooist law) is still working through legislation and not yet in effect, and a private certificate doesn't by itself guarantee skill or legality. So rather than the presence of a certificate, judge by whether they can show you healed cases across skin types, and whether the consultation reads your skin and tailors the technique to it.
✔ See whether they can show "healed" cases across a range of skin types
✔ Check that they don't insist on one technique, but recommend by skin type
✔ Ask whether they personally handle your healing and touch-up
The proof of experience isn't years — it's healed cases and an eye that reads skin.

Why be wary of "lowest price" and "event" deals?
The last skill is reading the ads. Lines like 'No.1 PMU in Seoul/Hongdae,' 'lowest price in the industry,' or 'today-only event price' make poor selection criteria. A "No.1" claim you can't verify, or a lowest price where you don't know what's included, is an ad with a weak signal. Compare price by what's included. At the same number, the real cost changes completely depending on whether the touch-up, pigment, and aftercare guidance are part of it. A price that's too low may have cut invisible costs like disposables or the touch-up, so for an accurate figure — which varies by area, design, and skin condition — it's best to be guided through it in consultation and on our pricing page.
✔ Compare what's included rather than "No.1 / lowest price" claims
✔ Check whether touch-up, pigment, and aftercare are in the price
✔ Ask what a suspiciously low price has cut to get there
Compare price not by the number, but by what's included.
How does CYAN hold itself to these standards?
What sets CYAN apart is a deep consultation grounded in clinical psychology, a nano-milling technique that works texture in 0.1mm increments, and experience proven through healed cases. The studio is built to practice the six standards above, exactly as written.
With my background in clinical psychology, I put the consultation first — listening fully and deciding together, rather than pushing a quick yes. The work itself focuses on naturalness through nano-milling, handling fine texture in 0.1mm increments. And the experience of teaching powder brows to clinics in Japan as a Korean instructor, together with data from more than 30,000 procedures, is the base for reading how color settles on each skin type. One thing you won't hear from us, though, is "the best, the only, flawless" — that judgment is yours to make, through healed cases and a consultation of your own.
✔ A clinical-psychology background — a consultation that listens fully and decides together
✔ 0.1mm nano-milling — natural, not simply darker
✔ Teaching experience in Japan + 30,000-procedure data for reading how color settles by skin
The proof of a good studio isn't the word "best" — it's healed cases you can check for yourself.
In closing
✔ Key 1: Hygiene — do they open a fresh needle in front of you?
✔ Key 2: Portfolio — are there unedited "healed" photos?
✔ Key 3: Consultation — do they review medications, history, and skin type?
✔ Key 4: Touch-up — is the inclusion and timing stated from the start?
✔ Key 5: Artist's experience — can they show healed cases across skin types?
✔ Key 6: Ads — don't be swayed by "No.1 / lowest price"; compare what's included.
The real standards are the things you can't easily see. CYAN is a semi-permanent makeup (PMU) studio in Hongdae (Mapo-gu), Seoul — and from areas like Gangnam or Myeongdong it's reachable by the Line 2 and Airport Railroad stops at Hongik University Station (travel time depends on where you start). Wherever you go, I hope these six standards lead you to a choice you won't regret.

CYAN is a semi-permanent makeup (PMU) studio, not a medical institution. Results and longevity vary by individual skin and aftercare. Pigment allergy, infection, and temporary swelling or redness are possible. Details are explained in the pre-procedure consultation.
Frequently Asked Questions
Can I choose a good PMU studio on star ratings alone?
Reviews and star ratings alone aren't enough. A review shows you whether a result looks pretty, but not the hygiene conditions it came from, what the healed color looks like a month later, or whether it suits your skin. Reviews are closer to a display case of only the results that went well, so it helps to also check the standards behind them — hygiene where the needle and pigment are opened fresh in front of you, unedited healed photos, a consultation that asks about your medications, history, and skin type, and a clear touch-up inclusion and timing.
Which photos should I look at in an eyebrow tattoo studio's portfolio?
Look at unedited "healed" photos, not right-after shots. Right after the procedure the color is at its most intense and crisp, which is the furthest from the color that actually stays, and PMU only settles into its healed color after about a month. It helps to look for before → right after → one-month healed sequences of the same person, photos taken in natural light without heavy filters, and cases with a skin tone and face shape similar to yours.
When should the touch-up usually happen?
For brows, 6–8 weeks after the first session is the right window. Skin renews on roughly a 28-day cycle, and the second pass should come after that keratinization cycle has turned over and the skin has fully healed, so the color sets in evenly. Weeks 4–6 — when the color softens by about 30–40% and stabilizes — are just the settling point, not the touch-up moment, and reinforcing too early can mean more pain and patchy color. A good studio states clearly from the start, in writing, whether one touch-up is included in the first price and what the cost is once the window passes.
When choosing a semi-permanent makeup studio in Seoul, why be wary of the "lowest price"?
Because price should be compared by what's included, not by the number. At the same amount, the real cost changes completely depending on whether the touch-up is included, and whether pigment and aftercare guidance are part of it. A price that's too low may have cut invisible costs like disposables or the touch-up, so always ask what's included. Definitive claims like "industry No.1 / lowest price" are also hard to verify and make weak selection criteria. The accurate cost varies by area, design, and skin condition, so it's best confirmed in consultation.
Should I judge an artist's experience by their certificates?
It's more accurate to judge by how many different skin types they've worked with through the healing stage than by certificates. In Korea, a national license for PMU artists (under the proposed tattooist law) is still in legislation and not yet in effect, and a private certificate doesn't by itself guarantee skill or legality. So rather than whether a certificate exists, look at whether they can show you healed cases across oily, dry, and sensitive skin, and whether the consultation reads your skin and tailors the technique to it.
Results and longevity vary by individual skin and aftercare. Pigment allergy, infection, and temporary swelling or redness are possible. Details are explained in the pre-procedure consultation.
