PMU vs Tattoos: What Does Semi-Permanent Really Mean?

"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 with a national qualification in clinical psychology, I wanted to work more deeply with the human face and the impression it leaves — so I became a PMU artist.From my studio in Hongdae, Seoul (Mapo-gu), I've completed more than 30,000 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?

Permanent makeup (PMU) is a form of cosmetic tattooing that places pigment in the skin.Eyebrow, lip and eyeliner tattooing describe the area and design.The term ‘semi-permanent’ does not establish that pigment stays only in the epidermis or will disappear completely.Pigment may remain after fading, and removal can be difficult.Discuss the design and future changes before proceeding.

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

Eyebrow tattooing and eyebrow PMU are broad terms.Powder brows are one technique within that group, using dots to create soft shading.Hairstrokes create hair-like lines; some designs combine both effects.These are not interchangeable technique names.Discuss skin condition, existing pigment and your intended result before choosing.

Is "lip tattoo" different from lip blush?

Lip tattooing is a broad term for cosmetic tattooing of the lips.Lip blush describes a soft colour effect; coverage and intensity depend on the design.It does not require one fixed inner-to-outer gradient.Existing lip colour may call for neutralisation or multiple sessions, so confirm the approach in consultation.

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.

Both are judged by the same thing — whether anyone can tell.

And "cover-up" and "color correction" — more new words?

Cover-up and color correction are the terms for concealing an old PMU result or correcting color that has shifted.

As PMU fades, its color can shift too.Shades that have drifted red or orange are relatively easy to cover, while color that has turned grey or bluish is trickier and needs a plan that neutralizes it first.So the heart of the work isn't "painting over" — it's reading which color to lay down first to neutralize what's already there. Discolored-brow correction and full cover-up work run deeper than this glossary, so if leftover pigment or color shift is your concern, see the PMU cover-up guide.

If the color already in the skin can't be read, the new color can't be predicted.

Then why is it called "semi-permanent"?

‘Semi-permanent’ does not promise complete disappearance after a fixed period. Pigment may fade but remain, and removal can be difficult. Skin, pigment, technique and aftercare affect the course. The name or a single duration cannot predict an individual result.

Which terms come up most in a consultation?

Knowing the words means the consultation is spent on decisions, not explanations.

Undertone is the colour the skin or lips already carry and the direction it leans. Residual pigment is the state in which colour from an earlier procedure has faded yet still shows through the skin, and a retouch is the step that fills in what did not hold the first time and lifts the finish.

Three words are enough to see what a quote has left out.

What if it never comes off… (about how long it lasts)

Fading does not mean the design can always be changed freely.Residual pigment and skin condition may limit correction options.Decide on a touch-up after assessing healing, and check the current pricing page for timing and costs.

So who is it good for?

PMU may appeal to people wishing to simplify makeup or adjust the appearance of brows or lips.An allergy to cosmetics does not make tattoo pigment a safe alternative.If you have a skin condition, allergies, scarring or previous surgery, ask a qualified clinician about suitability first.
