Q-switched and picosecond lasers shatter ink so the body clears it gradually, so most tattoos fade over a series of sessions spaced 6 to 8 weeks apart rather than in one visit.
Laser tattoo removal uses ultra-short pulses from Q-switched or picosecond lasers to break ink into tiny particles your body then clears, fading the tattoo over several sessions spaced 6 to 8 weeks apart. At our Incheon Airport (Yeongjongdo) location, Dr. Sunbeen Kim assesses your tattoo first, since color, depth, and size shape realistic clearance.
One-on-One guidance from a dedicated doctor, ensuring your skin is professionally monitored and treated from start to finish.

Laser tattoo removal is a non-surgical procedure that fades or clears unwanted tattoos by breaking down the ink trapped in the skin. Instead of cutting anything out, the laser delivers extremely short, high-energy pulses that shatter pigment particles into fragments small enough for the body’s immune cells to carry away over the following weeks. This is why removal happens gradually across a course of sessions rather than in a single appointment.
The two main technologies are Q-switched lasers, which fire in billionths of a second, and newer picosecond lasers, which fire even faster and can shatter certain inks more efficiently. Different wavelengths target different ink colors, so black is usually the most predictable to clear, while colors such as green and light blue are more stubborn and may need specific settings and additional visits. Tattoo age, depth, density, and layering over old tattoos all influence how a tattoo responds.
At Reberry Clinic, tattoo removal is doctor-led and tailored. At our Incheon Airport (Yeongjongdo) location near ICN, Dr. Sunbeen Kim, Medical Director, examines the tattoo, estimates a realistic number of sessions, and explains outcomes honestly in English. This access point suits international patients arranging removal around arrivals, stopovers, or transit through Incheon.
Laser tattoo removal relies on a principle called selective photothermolysis: pulses so brief that their energy is confined to the ink particles, shattering pigment while sparing surrounding skin. A Q-switched laser delivers pulses lasting billionths of a second (nanoseconds), while a picosecond laser fires roughly 1,000 times faster, generating a more photomechanical shockwave that can fragment certain inks into finer particles. Smaller fragments are easier for immune cells to clear, which is why picosecond devices sometimes reduce the number of sessions needed, though this varies by ink and skin. Wavelength choice is central because each color absorbs light differently: a 1064 nm setting targets dark inks like black and dark blue, a 532 nm setting addresses red and warm tones, and additional wavelengths such as 755 nm or 694 nm help with stubborn greens and blues. Because a single pass only breaks down part of the ink, and the body needs about 6 to 8 weeks to clear the fragments, most tattoos require a series of sessions. Skin tone also guides settings, since deeper tones need careful energy selection to reduce the risk of pigment change. The doctor selects device, wavelength, and spacing based on your tattoo’s colors, depth, and your skin type.

The doctor grades color, depth, size, and layering across the 6 parameters used to estimate how many sessions clearance may need.
Topical numbing is applied for about 20 to 30 minutes, and cooling protects the skin during the short laser pass.
Pulses lasting nanoseconds or picoseconds fragment the pigment, with 2 or more wavelengths matched to the tattoo’s ink colors.
Over the 6 to 8 weeks between sessions, immune cells gradually carry away the shattered ink, so the tattoo fades step by step.
Most tattoos need 3 or more sessions, and the doctor reviews fading at each visit before planning the next rather than promising full clearance.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.
Dr. Sunbeen Kim examines your tattoo’s colors, depth, and size, estimates a realistic session count, and explains the plan in English.
After about 20 to 30 minutes of numbing, a session usually takes 10 to 30 minutes depending on the tattoo’s size.
Removal runs as a course of several sessions spaced 6 to 8 weeks apart, so the tattoo fades progressively over months.
Fading builds with each session as the body clears shattered ink, and progress is reviewed before planning the next visit.
Cleared results are lasting, though some colors may leave faint residual pigment, and diligent aftercare between sessions protects the skin.
Laser tattoo removal fires ultra-short pulses that shatter ink into tiny particles your body’s immune cells then clear over the following weeks. Because each pass breaks down only part of the ink, tattoos fade gradually over several sessions. You can see the broader approach on our laser treatment page first.
Most tattoos need several sessions spaced 6 to 8 weeks apart, with small black tattoos usually needing fewer and professional multicolor work needing more. Clinical scales estimate the count from color, depth, size, and layering. Your doctor reviews fading between visits and adjusts the plan as your tattoo responds.
Black is usually the most predictable to clear because it absorbs a broad range of wavelengths, while green and light blue are the most stubborn and may need specific settings and extra sessions. Red and warm tones respond to a 532 nm wavelength. Your laser treatment plan is matched to your ink.
Q-switched lasers fire in billionths of a second, while picosecond lasers fire roughly 1,000 times faster, shattering some inks into finer particles that can clear more efficiently. Picosecond devices sometimes reduce sessions for certain colors. Your doctor chooses the device and wavelength based on your tattoo’s colors, depth, and your skin type.
Most patients describe a snapping or hot-elastic sensation, but topical numbing applied for about 20 to 30 minutes and cooling make sessions tolerable. The discomfort is brief since each pass is quick. Your doctor checks your comfort throughout and can adjust cooling and pacing for sensitive areas.
Expect temporary redness, swelling, and sometimes small blisters or pinpoint bleeding that settle over several days. Crusting can form and should not be picked. Most people return to daily activities quickly, but the treated area needs gentle care and strict sun protection until it heals between sessions.
Many tattoos fade substantially or clear over a full course, but some colors and heavily layered inks may leave faint residual pigment. Complete clearance is not guaranteed for every tattoo. Your doctor gives a realistic outlook at consultation based on your ink, depth, and skin so expectations are grounded.
Fading builds gradually across sessions rather than after one visit, as the body clears shattered ink over the 6 to 8 weeks between treatments. Some lightening is often visible after the early sessions. Your doctor reviews progress at each visit so the plan stays matched to how your tattoo responds.
Laser removal can be used across skin tones, but deeper tones need careful wavelength and energy choices to lower the risk of pigment change. Your doctor assesses your skin type at consultation and selects conservative settings where needed, so treatment is both effective and appropriately cautious for your skin.
Yes, older or already-faded tattoos often respond well because the ink has partly broken down over time, sometimes needing fewer sessions than fresh work. Very deep or amateur ink can vary. Your doctor assesses the tattoo’s age, depth, and density to set a realistic plan for fading or clearance.
Keep the area clean, apply any prescribed ointment, avoid picking scabs, and protect the skin rigorously from sun until it heals. Gentle skincare supports recovery. A supportive skin care routine between sessions helps the skin heal evenly and reduces the chance of pigment change.
Most adults wanting to fade or remove an unwanted tattoo who can commit to a multi-session course are suitable. Active infection, a fresh tan, or a keloid history need assessment first. A laser treatment consultation grades your tattoo and confirms it fits your skin and ink.
Yes, international patients can be seen at our Incheon Airport (Yeongjongdo) location near ICN, convenient for arrivals, stopovers, and transit visits. Dr. Sunbeen Kim, Medical Director, assesses your tattoo with English-language support. You can review the approach on our laser treatment page.
A single session needs only 1 to 2 days, covering a consultation and the quick laser visit. Because removal runs as a course spaced weeks apart, many international patients start near Incheon Airport and plan later sessions around future trips. Our English-speaking team helps coordinate the timing.
Yes, flying within a day or so is generally fine because laser tattoo removal is minimally invasive. The area may be tender or blistered, so keep it clean, moisturised with prescribed ointment, and out of the sun while you travel. This aftercare suits our Incheon Airport location for transit patients.
International patients can complete a removal course across several trips, and the clinic helps schedule sessions and remote check-ins in English between visits so the plan stays on track. You can continue supportive skin care at home, and your treatment notes are kept on file for continuity.
