Last month, black tattoo removal
was completed in an average of 8 sessions.
Please check this before reading
Q. I’ve had more than 10 sessions elsewhere,
so why isn’t it fading?
A. If the device wavelength and pulse width don’t match,
the ink particles won’t break down as well.
When switching to PicoWay,
it is often possible to reduce the number of sessions by about 30%.
Q. Does the number of sessions
really 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 actually hard to explain with
just one number, like “how many sessions”
Tattoo removal is a procedure that uses a laser to
break ink particles inside the skin into tiny pieces,
encouraging immune cells to clear them away.
Unlike conventional lasers, picosecond lasers have
a pulse width measured in picoseconds rather than nanoseconds,
so they break the ink into much finer particles.

Key Insight
Depending on the tattoo’s color, depth, and size,
most cases require about 5 to 10 sessions.
When treated with PicoWay,
it is often possible to reduce the number of sessions by about 30% compared with conventional lasers.

The number of tattoo removal sessions can vary quite a bit
depending on the color, depth,
and size.
Usually, 5 to 10 sessions is a common range,
and when using PicoWay,
it is often possible to reduce the number of sessions by about 30%.
A man in his 30s who visited us last month had
already received 8 sessions elsewhere,
but there was still a faint shadow. After switching the wavelength to PicoWay and having 3 sessions, it became almost invisible.
That’s because the ink particle size and laser pulse width need to match
for the shock waves to break them down effectively.
Director Wi Young-jin’s Key Summary
For a small solid black tattoo, 3 to 5 sessions,
and for a large tattoo with mixed colors, about 8 to 12 sessions
is a good estimate.
If the wavelength is properly matched and a picosecond device is used,
the number of sessions can often be reduced by about 30%.

Estimated Session Comparison by Tattoo Type
Tattoo Type | Estimated Sessions | Notes |
Amateur black tattoo | 3–5 sessions | Ink is shallow and responds quickly |
Professional black lettering | 5–8 sessions | Darker and deeper, so it takes longer |
Mixed-color tattoo | 8–12 sessions | Requires individual targeting by wavelength |
Permanent makeup | 2–4 sessions | Be careful about color changes after treatment |
Cover-up / touch-up work | 10+ sessions | Ink layers overlap, so it takes longer |
To be honest,
it’s difficult to determine the exact number of sessions at the first visit.
It’s more realistic to assess the response after 3 to 4 sessions,
then adjust the remaining sessions accordingly.
The three questions we hear most often in the clinic
Q1. How long should the interval between sessions be?
We usually recommend an interval of 6 to 8 weeks.
The broken-down 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 depends on the area and the number of colors,
so it’s best to set your overall budget before starting.
An exact estimate is
available after we see the actual tattoo during consultation.
Q3. Can scars or pigmentation remain?
When treatment is performed with a picosecond device at the appropriate energy level,
the risk of scarring is low.
If you consistently protect the area from UV exposure after treatment,
most people recover nicely.
If anything is unclear,
I’ll examine it directly in the clinic and guide you.
This has been Dr. Wi Young-jin.

Averages are a starting point, not your number. At Beautystone the Kirby–Desai assessment is used in consultation to review skin type, location, ink amount, layering, scarring and colour, which gives an expected session range for your own tattoo. Responses differ between people, so we treat that range as an estimate and adjust it as sessions progress and we can see how your skin is clearing the pigment.
