Key Points: Tattoo ink sits deep in the dermis, and different ink colors respond to different laser wavelengths — which is why a single-wavelength device often falls short. ADO Clinic uses pico laser combined with multi-wavelength technology (532nm, 585nm, 650nm, 1064nm) to target tattoos by color and depth, from solid black lettering to multicolor designs and semi-permanent brows.
Why Is Tattoo Removal So Difficult in the First Place?
Tattoo ink is deposited into the dermis — a deep layer of skin — precisely because it is designed to be permanent. Reaching that depth accurately is the first challenge any removal method must overcome.
Each ink color absorbs a different wavelength of light. Black responds in a relatively predictable way, but reds, yellows, and blues each require their own specific wavelength. Using a mismatched wavelength means the ink particles are not broken down efficiently, which increases the number of sessions needed.
Beyond color, the density and layering of ink vary by artist and by how many touch-up sessions the tattoo has received. Tattoos that look similar on the surface can behave very differently during treatment — meaning what appears straightforward may take longer than expected.
How Does Pico Laser Multi-Wavelength Technology Remove Tattoos More Effectively?
Pico laser delivers energy in pulses measured in picoseconds — one trillionth of a second. This ultra-short pulse duration shatters ink particles into extremely fine fragments, making it easier for the body to absorb and eliminate them naturally. Smaller fragments clear faster, which can shorten the interval between sessions.
Because energy is released so rapidly, heat has little time to spread to surrounding tissue. This characteristic is associated with a reduced risk of thermal damage compared with older laser technologies.
ADO Clinic applies what it calls Adormaizing Multi-Wavelength technology, combining four wavelengths — 532nm, 585nm, 650nm, and 1064nm — within a single treatment. Each wavelength is selected based on the color and depth of the ink being targeted, allowing the device to address surface pigment and deeper dermal layers in the same session. This approach covers solid black tattoos, multicolor designs, and semi-permanent makeup correction within one platform.

How Does Tattoo Location and Size Affect the Number of Sessions?
Giving a fixed session count is difficult because ink density and color composition matter as much as size. The same area of skin can behave very differently depending on how the tattoo was applied.
Semi-permanent eyebrows are often assumed to be easier to remove because the pigment sits at a shallower depth. However, brows that have been corrected multiple times may have layered pigment that requires more sessions than a straightforward single-color tattoo.
Single-line lettering is small in area but often has dense, tightly packed ink. Black-only lines are relatively predictable, but lettering with a black outline and colored fill requires different wavelengths for each element, adding complexity to treatment planning.
For larger tattoos — business-card size and above — the combination of increased surface area and multiple colors makes wavelength selection more involved. A multi-wavelength approach is particularly relevant here, since no single wavelength can address every color present in one pass.
What Should You Look for When Choosing a Tattoo Removal Clinic in Gangnam?
Rather than focusing on a device brand name or a promised session count, it is more useful to ask how the clinic identifies which wavelengths are appropriate for your specific ink colors and depths. A thorough consultation should review the color composition, estimated ink density, and any previous removal or correction history.
The variables that most affect outcomes — ink density, layering, and exact color composition — are not always visible to the naked eye. A structured pre-treatment assessment helps set realistic expectations and guides wavelength selection from the first session onward.
Frequently Asked Questions
Why does tattoo removal require multiple sessions?
Each session breaks ink particles into smaller fragments, which the body then processes and eliminates. Multiple sessions are needed because the body requires time between treatments to clear those fragments before the next round of laser energy is applied.
Can all tattoo ink colors be removed with laser?
Most colors can be addressed, but each color responds to a different laser wavelength. Black is generally the most responsive. Colors such as red, yellow, and blue require specific wavelengths, which is why multi-wavelength devices tend to produce more complete results on multicolor tattoos than single-wavelength alternatives.
Is pico laser safer for the skin than older tattoo removal lasers?
Pico laser pulses are extremely short, which limits heat transfer to surrounding tissue. This is generally associated with a lower risk of thermal side effects compared with nanosecond-based lasers, though individual outcomes vary depending on skin type, ink composition, and treatment settings.
Does semi-permanent makeup removal differ from regular tattoo removal?
Semi-permanent pigment is typically placed at a shallower depth than conventional tattoo ink, which can affect how it responds to laser. However, brows or eyeliner that have been corrected or layered multiple times may have accumulated pigment that requires careful assessment and potentially more sessions.
How should I prepare for a tattoo removal consultation?
It helps to know the approximate age of the tattoo, the number of colors it contains, whether it has been touched up or previously treated, and the location on the body. This information allows the clinician to assess ink density and plan an appropriate wavelength approach before treatment begins.
