Brow Tattoos in Korea: Cover-Up, Colour Correction or Removal?

"That eyebrow tattoo I got a few years ago has gone red, and I can't stop noticing it :("

"My brows from another shop are uneven and a little blue — should I remove them or cover them up?"

If you're unhappy with an old semi-permanent makeup result and unsure how to fix it, you are far from alone.

Hi, I'm CYAN (HSIN SIAN), the artist behind CYAN PMU. I came to permanent makeup with a national qualification in clinical psychology, and I now serve as a semi-permanent makeup competition judge. Since opening my studio in Hongdae, Seoul, I've met just as many people coming in to fix an old result as first-timers.

Today I want to walk you through one question that confuses almost everyone: how PMU removal differs from a PMU cover-up (correction). The honest answer can't be settled by a single photo — it depends on the color, depth, and shape of what's still left in your skin.

Why does an old brow tattoo change color over time?

The three most common complaints are color shift, blurring, and asymmetry.

Semi-permanent makeup places pigment in the upper layers of the skin, so as the brown fades, the underlying undertone surfaces — which can read as red, blue, or gray.When pigment was implanted too deep or at the wrong needle angle, it can spread sideways into blurring (a blowout), and if the left and right brows weren't matched well to begin with, fading can make the asymmetry stand out even more.

"Semi-permanent means the color fades — not that it disappears cleanly on its own."

Often it didn't change — it was always going to settle into that colour.

Why the color drifts to red, gray, or blue in particular — and how each is neutralized — is covered in depth in the brow discoloration & color correction guide.

What's the difference between PMU removal and a cover-up?

In short: removal takes pigment out, while a cover-up corrects by layering over it.

PMU removal reduces or draws out the remaining pigment itself.It splits broadly into laser and remover solution methods — and importantly, laser removal is a medical procedure, so it must be done at a licensed medical institution, not a PMU studio.

A PMU cover-up (correction) doesn't pull the old color out. Instead, it lays new pigment and a new design on top to set things right. The key here is color neutralization. For a brow that has gone red, a complementary tone is mixed in to cancel the redness; for blue or gray tones, a warm tone neutralizes them back toward a natural brown. Exactly which complementary color is used for which cast is covered in the brow discoloration & color correction guide.

Whether to cover or remove isn't a preference; the pigment still in the skin decides it.

You can see real tone changes on our services and gallery pages.If you're getting it in Hongdae, see the Hongdae cover-up page too.

Can my brows be covered, or do they need to be removed?

Honestly, this can't be decided without seeing them in person. Two "red brows" can be completely different cases.

If the remaining color sits light and shallow, color-neutralizing cover-up is usually enough to correct it.But if it's dark, deep, or covers a wide area, new color laid on top can still show the old color underneath and turn muddy — so a lightening step may be needed first. When laser or another medical removal looks necessary, we recommend a medical consultation first.

That's why, for fixing a bad PMU result, a studio that tells you honestly what is and isn't possible matters more than flashy before-and-afters.As the PMU principle goes — adding is easier than taking away — the safest path is to correct gradually and lightly, not all at once.

A studio that won't judge from one photo is the one to trust over the studio that will.

How does CYAN handle other-shop corrections and color neutralization?

One of the requests we get most often is fixing PMU that was done somewhere else.

The challenge of an other-shop correction is that we have to read a color we didn't put in. We can't see which pigment went in or how deep, so we use color theory to reverse-engineer the tone that's surfacing now and decide the neutralization direction from there. And with my clinical-psychology background, I make a point of first hearing the feeling underneath — "I want this fixed, but I'm scared it'll go wrong again" — and agreeing honestly on what's possible before we start.

"The first step in fixing a bad PMU isn't drawing something new — it's reading exactly what's left behind."

Telling you it can't be covered is also part of doing the correction properly.

What should you bring to the consultation?

One photo of your brows taken in daylight matters most.

Residual pigment is the state in which colour from an earlier procedure has faded yet still shows through the skin, and whether it reads red or grey changes the approach entirely.Indoor lighting hides that difference.

One piece of history left unsaid changes the whole assessment.

How many sessions, and what happens in between?

We do not cover it dense in one go; we go in thin layers.

Complementary neutralising is the method of mixing in the opposite colour to push down what is surfacing and bring it back to a natural brown, and red versus grey-blue run in exactly opposite directions.So it is normal for the colour not to be fully brown after the first session.

A studio that warns you about the in-between stage is one that can see it through.

Is aftercare different following a cover-up?

You have to be more careful with sun than after ordinary work.

The healing period is the stretch in which scabs form, fall away and the colour settles, usually 4～6 weeks.In a cover-up the old colour underneath and the new colour settle together, so heavy sun in that window can shift the tone again.

With a cover-up the result is decided in healing more than on the bed.

Why does it turn red, blue, or grey?

First, be reassured. The color changing isn't because you cared for it wrong. It's mostly something that happens as pigment and skin react naturally.

Brown pigment contains a component called iron oxide, and over time it oxidizes or shifts position a little.Then what was brown surfaces as a red or orange cast.Also, if pigment goes too deep into the skin, a "Tyndall effect" of scattering light arises, showing through like blue-grey.Add pigmentation from the procedure's stimulation on top, and it can darken dully too.

And let me note one thing.Because of the name "semi-permanent," it's easy to think "it'll vanish without a trace over time," but it's a bit different. It does fade, but grey or blue residual color often remains faintly. So when doing a new procedure, this remaining color must be calculated in.

Otherwise it blends with the new color and an off color comes out.

Q. What is complementary correction? Is it different from covering color?

Yes, it's different. Complementary correction isn't "covering" — it's "settling down."

It slightly mixes the opposite color (complement) into the discolored color to lower its saturation.Colors facing each other on the color wheel cancel each other's cast. So for a blue or grey cast we add orange tones, for a red shift we add green/khaki tones, and for a darkened black we add yellow tones to suppress the cast.

Sounds hard, right?Picture the color corrector you use in makeup — green for redness, apricot for bruises or blue.Same principle exactly.

But here's where we have to be honest. Complementary correction makes the remaining color "less visible" — it doesn't remove pigment.So it's truly important to determine in the consultation whether correction alone is enough, or whether tidying (removal) comes first.

This isn't something you get from a pigment chart — it's a feel built from seeing countless cases. (I'm a little… confident about this part.)

Removal — laser and remover, and the honest limits

When covering won't solve it, we consider "removal" to lighten the pigment. There are broadly two.

Laser shatters pigment particles small so the body can expel them.But there's a trap here. Iron oxide commonly used in PMU, eyeliner, and lips, or titanium dioxide used in flesh-tone or pink corrections, can undergo "paradoxical darkening" — turning grey or black — when hit with laser. Trying to remove it makes it darker. So the principle is that laser removal is done at a medical facility, first testing on a small inconspicuous area before proceeding.

The saline (remover) method draws pigment up by osmotic pressure and expels it with the scab.The darkening risk is relatively lower, but effectiveness varies greatly between people and it can take several sessions.

With either method, it's hard to promise it's all erased in one go. You have to go in stages with recovery time. This is the honest thing to say.

In short

CYAN is located in Hongdae, Seoul (Mapo-gu), an easy subway ride from Gangnam and Myeongdong.For what's actually possible and the cost, see our pricing and contact and booking pages. This was CYAN (HSIN SIAN) of CYAN PMU in Hongdae.

CYAN is a semi-permanent makeup (PMU) studio, not a medical institution. Laser pigment removal and any case requiring medical judgment must be handled at a licensed medical institution. Whether a cover-up or correction is possible depends on the remaining color and skin condition. 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.
