PMU vs Tattoo: Eyebrow, Lip & Eyeliner Terms Explained (Seoul Guide)

"Is eyebrow tattoo the same thing as eyebrow semi-permanent makeup? I'm so confused."

"I searched 'lip tattoo' and lip blush kept coming up… are they the same?"

"And what is scalp SMP — do they actually tattoo your head?"

Hello, I'm CYAN (HSIN SIAN), founder of CYAN PMU ^^

After working as a nationally licensed clinical psychologist, I wanted to work more deeply with the human face and the impression it leaves — so since 2018 I've walked the path of a PMU artist. From my studio in Hongdae, Seoul (Mapo-gu), I've completed more than 40,000 treatments, and the question I'm asked most often is about terminology. When "tattoo," "semi-permanent," "blush," and "SMP" all blur together in search results, of course it's confusing. This isn't an ad — it's a clean guide to untangle the words. Give it three minutes and your search results will look completely different ^^

If you're flying in from abroad, CYAN is easy to reach: Myeongdong is about 25 minutes and Gangnam about 30 minutes to Hongdae by subway.

What's the real difference between semi-permanent makeup and a tattoo?

Semi-permanent makeup (PMU) and tattooing differ in depth and purpose — and almost every cosmetic treatment done on the face is PMU.

A tattoo deposits pigment deep into the dermis to set strong color in a single session and keep it for life. Semi-permanent makeup, on the other hand, places a thin layer of natural, skin-toned color much more shallowly, near the boundary of the epidermis and dermis. That's why it softens gradually over time, and why a retouch about a month later lets us reinforce the color and refine the design. Unlike the bold, varied palette of tattoos, PMU uses a limited range of natural shades to make everything look "like it was always there" — a cosmetic treatment, not body art.

You can see how our four core treatments are structured on the services page.

Are "eyebrow tattoo" and "eyebrow PMU" the same word?

"Eyebrow tattoo" is just a search term — in reality it means eyebrow PMU, such as powder brows.

In everyday use, eyebrow tattoo, eyebrow semi-permanent makeup, and powder brows all point to the same area. The proper name is powder brows (soft shading), and "eyebrow tattoo" is simply what people type into the search bar. By technique, microblading (natural hair-stroke brows) uses a fine blade-like tool to draw individual strokes that mimic real hairs, while shading (powder) builds up tiny dots into a soft, makeup-like gradient. The recommended technique depends on your skin type — for oily and combination skin, crisp strokes tend to blur, so shading-based styles often settle more reliably.

Is "lip tattoo" different from lip blush?

"Lip tattoo" is the umbrella term for lip PMU, and lip blush is the go-to choice for a natural flush.

Think of these as variations within the same lip PMU family. Among the treatments people call lip tattoo or lip PMU, the most loved right now is lip blush. Lip blush deposits color thinly — deeper at the center, lighter at the edges — as if staining the lips, for a soft, tint-like natural color. Filling the entire lip with solid, lipstick-like color is called full lips instead. And if your natural lip color is dark or dull, it often isn't a one-session job: we first balance the darkness with a neutralizing pigment to create a brighter base, then build the color you want in a later session.

Pricing and longevity for each treatment are laid out clearly on the pricing page.

What about eyeliner tattoo and scalp SMP?

Eyeliner tattoo is lash-line PMU, and SMP is scalp PMU that draws follicles — naturalness is the key to both.

Eyeliner tattoo refers to lash-line semi-permanent makeup. The crucial point: pigment is placed only on the skin outside the lash line. The inner rim of the eyelid (the waterline / tightline) is directly tied to eye health, so the safe principle is to never treat it. SMP (scalp micropigmentation / scalp PMU) places tiny dots that resemble hair follicles onto the scalp, making hair look fuller or softly camouflaging scars. Because it builds density with dots rather than drawing hair strands, it looks natural once settled and tends to last longer than other treatments.

Then why is it called "semi-permanent"?

Semi-permanent doesn't mean "makeup that washes away" — it's a treatment that lasts a long time while fading slowly.

This is the biggest misconception, so let's settle it. The name "semi-permanent" dates back to an era when pigment was placed poorly and faded quickly, and it stuck partly because clients liked the lower commitment compared to a permanent tattoo. But properly placed pigment may lighten over time without disappearing entirely — some residual color can remain. So the accurate phrase isn't "vanishes without a trace" but "fades gradually." Because color can stay for the long term, the design and shade are decisions to make carefully at your very first consultation.

To wrap up, here are today's three key takeaways. First, almost every cosmetic treatment on the face is shallow-depth PMU, and eyebrow tattoo, lip tattoo, and eyeliner tattoo are all just other names for PMU. Second, each area has its own signature name — powder brows for brows, lip blush for lips, SMP for the scalp. Third, remember that "semi-permanent" doesn't wash away cleanly; it fades gradually.
