Laser removal shatters ink so the body clears it over roughly 6 to 8 weeks per session, so most tattoos fade across several sessions rather than in one visit.
Laser tattoo removal uses Q-switched and picosecond lasers to break ink into tiny fragments your body clears over the following weeks, fading the tattoo across several spaced sessions. The number of sessions depends on ink color, depth, and size. For international patients near Hongdae (Hongik Univ.) Station, treatment is provided at our Seoul locations with English support.

Laser tattoo removal is a non-surgical procedure that fades or clears a tattoo by breaking down its ink with rapid, high-energy light pulses. The laser targets pigment particles trapped in the skin and fragments them into smaller pieces. Your immune system then gradually carries those fragments away over the weeks that follow, so the tattoo lightens progressively rather than disappearing at once. This is why removal is done as a series of spaced sessions, not a single appointment.
Two laser families are used. Q-switched lasers deliver nanosecond pulses across several wavelengths, making them versatile for different ink colors. Picosecond lasers use even shorter pulses that rely more on a photoacoustic (pressure-wave) effect, which can fragment ink more efficiently and often clears many tattoos in fewer sessions. Different colors respond to different wavelengths, so the clinic’s doctors choose the laser and settings that suit your specific ink and skin type.
Realistic expectations matter: black ink usually clears fastest, while colors such as green and blue can be more stubborn, and some ink may not disappear completely. At Reberry Clinic, removal is doctor-led and staged for safety. For international patients searching near Hongdae (Hongik Univ.) Station — 홍대입구역 — treatment is carried out at our Seoul locations (Gangnam, Myeongdong), easily reached from 홍대입구역, with full English support.
Tattoo ink sits in the dermis as particles too large for the body to remove on its own, which is why tattoos are permanent without treatment. A tattoo-removal laser fires pulses lasting only nanoseconds or picoseconds, delivering intense energy in a fraction of a second so the ink absorbs it and shatters into microscopic fragments. Nanosecond Q-switched lasers rely largely on a photothermal effect, while picosecond lasers, with pulses roughly 1,000 times shorter, produce a stronger photoacoustic effect that can break ink more efficiently and with less surrounding heat. Wavelength choice targets color: 1064 nm suits dark inks, 532 nm addresses red and warm tones, and additional wavelengths help with greens and blues. After each pass the fragmented ink is cleared by the immune system over about 6 to 8 weeks, which is why sessions are spaced and why 1 session is never enough. The clinic’s doctors match wavelength, energy, and pacing to your ink colors and skin type, keeping settings conservative on darker tones to reduce the risk of temporary pigment change.

Doctors evaluate ink colors, depth, size, and skin type across about 5 factors to plan the laser and realistic session range.
Topical numbing or cooling is used for comfort, and a session typically takes about 10 to 30 minutes depending on tattoo size.
The laser fires 1 rapid pulse after another in nanoseconds or picoseconds, fragmenting ink into pieces small enough for the body to clear.
The immune system removes fragmented ink over about 6 to 8 weeks, which is why sessions are spaced rather than back to back.
Most tattoos need several spaced sessions, and the doctor reviews fading each time to adjust wavelength and settings.

The clinic’s doctors assess ink colors, depth, and skin type, then explain the laser choice and realistic session range in English.
After a short numbing period, a session usually takes about 10 to 30 minutes depending on the size of the tattoo.
Sessions are spaced roughly 6 to 8 weeks apart so the body clears ink and the skin fully recovers between visits.
Ink fades gradually across the sessions, with black clearing first and colors like green or blue often needing more passes.
Cleared ink does not return, though some colors may not fully clear, and diligent aftercare protects the skin between sessions.
Laser tattoo removal is a non-surgical procedure that fades a tattoo by breaking ink into tiny fragments the body clears over the following weeks. It uses Q-switched or picosecond lasers over several spaced sessions. You can read more about the technology on our laser treatment page.
The laser fires pulses lasting nanoseconds or picoseconds that shatter ink particles into fragments small enough for your immune system to carry away. The tattoo then fades gradually over about 6 to 8 weeks after each session. This is why removal is staged rather than achieved in a single visit.
Q-switched lasers use nanosecond pulses and are versatile across ink colors, while picosecond lasers use much shorter pulses with a stronger photoacoustic effect that can clear ink in fewer sessions. Your doctor chooses the best fit for your ink and skin type. Learn more on our laser treatment page.
Most tattoos need several sessions spaced about 6 to 8 weeks apart, though the exact number depends on ink color, depth, size, and skin type. Black-only designs often clear faster than dense multi-color pieces. Your doctor gives a realistic estimate at consultation and reviews it as the ink fades.
Yes, ink color strongly affects removal because different colors absorb different laser wavelengths. Black ink usually clears fastest, red responds well, while greens and blues can be more stubborn and need more passes. A multi-color tattoo therefore typically takes longer than a same-size black design to fade.
Most people describe a snapping, elastic-band sensation on the skin during the pulses. Comfort measures such as cooling or topical numbing are used to make sessions tolerable. The area may feel tender briefly afterward. Your doctor explains what to expect for your specific tattoo before the first session.
Downtime is usually minimal, with temporary redness, mild swelling, or small crusts that settle over several days after each session. You can generally return to daily activities quickly. Keeping the area clean and protected from sun between sessions helps the skin recover and the ink clear efficiently.
Fading builds gradually as the body clears fragmented ink over about 6 to 8 weeks per session, so it appears between visits rather than immediately. Some layers lighten before others. Your doctor reviews progress at each session and adjusts the laser and settings to keep the tattoo fading steadily.
Many tattoos fade substantially, but some ink, especially certain colors or very dense professional work, may not clear completely. Removal aims to fade or clear as much as safely possible. Your doctor sets realistic expectations at consultation so you understand the likely outcome before starting a course.
Laser tattoo removal is widely performed and generally considered safe when a trained doctor matches wavelength and settings to your ink and skin type. Conservative settings reduce risks like temporary pigment change or blistering. You can review the doctor-led approach on our laser treatment page first.
Yes, deeper skin tones need more conservative laser settings to protect surrounding pigment and reduce the risk of temporary lightening or darkening. This careful pacing can mean more sessions. Your doctor accounts for your skin type so the plan stays both safe and effective for your particular skin.
Yes, partial fading is common when preparing for a cover-up, since a lighter base helps a new tattoo sit better. This usually needs fewer sessions than full removal. Your doctor maps which areas to fade and how many passes each needs, matching the plan to your cover-up goal.
Keep the area clean, apply any prescribed ointment, avoid picking crusts, and use diligent sun protection between sessions. Sunscreen reduces the risk of pigment change on treated skin. A gentle skin care routine supports healing so each session builds on the last effectively.
There is no operating Reberry Clinic branch in Hongdae itself yet. Patients searching near Hongdae (Hongik Univ.) Station — 홍대입구역 — are cared for at our Seoul locations (Gangnam, Myeongdong), easily reached from 홍대입구역, with full English support. See options first on our laser treatment page.
For a single session, 1 to 2 days covers a consultation and treatment. Because full removal needs sessions spaced 6 to 8 weeks apart, many international patients begin in Seoul and return, or complete a few passes per trip. Our English-speaking team helps coordinate timing around your travel plans.
Yes, flying within a day or so is generally fine, since laser tattoo removal is non-surgical and localised. Keep the treated area clean, moisturised, and protected from sun while you travel. If crusting or blistering occurs, follow your doctor’s aftercare so the skin heals well between sessions.
International patients often complete removal across several trips, spacing sessions the recommended 6 to 8 weeks apart, and the clinic offers remote check-ins in English between visits. Your progress photos and notes are kept on file, and you can continue supportive skin care at home for continuity.
