Of the 23 people we consulted last month,

tattoo removal averaged 7.2 sessions.

Q. I’ve had it treated more than 10 times elsewhere

so why isn’t it fading?

A. If the device wavelength and pulse width don’t match,

the ink particles don’t break down as well.

Switching to PicoWay

can often reduce the number of sessions by about 30%.

Q. Does the number of sessions

vary that much by color?

A. Yes, black fades quickly, but red, yellow, and green

take much longer because the wavelengths are different.

Why it’s hard to explain with just

one number like "how many sessions"

Tattoo removal works by breaking the ink particles in the skin

into tiny pieces with a laser,

and then prompting immune cells to clear them away.

Unlike conventional lasers, pico lasers

have pulse widths in picoseconds rather than nanoseconds,

so they’re structured to break the ink down more finely.

Dr. Wi Youngjin’s

key insight

It depends on the tattoo’s color, depth, and size, but

it usually takes about 5–10 sessions.

If you use PicoWay, you can often reduce the number of sessions by about 30%

compared with conventional lasers.

— Dr. Wi Youngjin (Beauty Stone Clinic, Hongdae)

Tattoo removal session counts vary quite a bit depending on color, depth,

and size.

Usually 5–10 sessions is the common range,

and using PicoWay can often reduce the number by about 30% compared with

traditional methods.

A man in his 30s who came in last month

had 8 sessions elsewhere, but

remnants remained; after switching the wavelength to PicoWay and

doing 3 sessions, it faded to the point of being barely visible.

That’s because the ink particle size and laser pulse width need to match

for the shockwave to break them into tiny pieces.

Dr. Wi Youngjin’s key summary

For a small black single-color tattoo, 3–5 sessions,

for a large multicolored tattoo, 8–12 sessions,

is a good rule of thumb.

If a pico device is used with the correct wavelength,

the number of sessions can be reduced by about 30%.

Expected session count by tattoo type

To be honest,

it’s hard to determine the exact number of sessions at the first visit.

A practical approach is to see how it responds after 3–4 sessions,

and then adjust the remaining sessions.

The three questions most often asked in the consultation room

Q1. How far apart should the sessions be?

We usually recommend intervals of 6–8 weeks.

The broken ink particles

need time to be cleared by immune cells.

If you repeat treatment too soon, the risk of side effects increases.

Q2. How much does one session cost?

It varies depending on the area and number of colors,

so it’s best to set your total budget in advance.

An exact quote can only be given

after seeing the actual tattoo during consultation.

Q3. Can scars or pigmentation remain?

If performed with a pico device at an appropriate energy level,

the risk of scarring is low.

If you consistently protect the area from UV after treatment,

most cases heal cleanly.

If anything is unclear,

I’ll look at it in the consultation room and explain it to you directly.

That’s all from Wi Youngjin.
