Ink is not erased. It is broken up and carried away.
The laser fragments tattoo pigment into particles small enough for immune cells to remove. That distinction explains everything about the process: why it takes months, why intervals matter, and why some colours are far harder than others.
Different ink colours absorb different wavelengths, so no single laser handles every tattoo. Black and dark grey respond to 1064nm and 755nm; red and orange to 532nm; green and blue to 755nm and 1064nm. Purple, light blue and yellow are the most resistant. Intervals of six to eight weeks or more between sessions are standard, because clearance depends on your immune system doing the removal.
Colour by colour
| Ink colour | Wavelength | Device | Response |
|---|---|---|---|
| Black, dark grey | 1064nm · 755nm | PicoPlus, PicoSure | Generally responds well |
| Red, orange | 532nm | PicoPlus | Usually responsive |
| Green, blue | 755nm · 1064nm | PicoSure, PicoPlus | Treatable |
| Purple, light blue, yellow | 755nm, multiple passes | PicoSure with adjunct devices | Resistant — expect more sessions |
| Permanent makeup (brow, lip) | Test spot first | Assessed individually | Risk of darkening — approached cautiously |
Fractional and Alma Hybrid devices are used as adjuncts for residual ink in resistant colours and for scarring or textural change. Excel V is considered where vascular redness accompanies the site.
Why the approach is adapted for Asian skin
Skin with more melanin absorbs more laser energy that was intended for the ink. That has two consequences: less energy reaches the target, and more heat is deposited in the skin itself — raising the risk of post-inflammatory hyperpigmentation and, at high energy, scarring.
The response is a deliberately conservative protocol: lower energy across more sessions, longer intervals — six to eight weeks or more generally, and eight to twelve weeks for deeper skin tones — and a preference for 1064nm, which is absorbed less by skin melanin. For coloured ink and permanent makeup, a test spot is performed first and assessed before committing to the full area.
Patients sometimes read this as slow. It is the difference between a tattoo that clears and a permanent pigment change where the tattoo used to be. Pushing energy to compress the timeline is the main way tattoo removal produces a worse outcome than the tattoo.
Permanent makeup is a different problem
Semi-permanent cosmetic pigment sits in a shallower layer than tattoo ink and is chemically different — frequently containing iron oxide or titanium dioxide. Those compounds can undergo a chemical change under laser energy and darken instead of fading. Peach, flesh-toned and white pigments are the highest risk, and a single unwise pass can turn a pale brow pigment dark grey.
For this reason permanent makeup is approached with a test spot first, assessed after a proper interval, and only then extended. If you have had brow, lip or eyeliner pigment applied and want it removed, mention the colour and, if you know it, what was used — and be prepared for the honest answer that some pigments are treated cautiously over a long period rather than quickly.
What to expect afterwards
Redness, swelling, fine crusting and sometimes blistering can occur at the treated site. This is part of the expected sequence rather than a complication, and the instruction is the same as always: do not pick, keep it clean and protected, and avoid sun on the area.
Excessive energy can leave scarring, or produce pigment change in either direction — hypopigmentation, where the treated area becomes lighter than the surrounding skin, or hyperpigmentation, where it becomes darker. Both are why the conservative protocol exists.
For visitors: this is not a treatment that fits into a trip. Sessions are spaced six to eight weeks apart at minimum, and a meaningful result requires several. If you begin a course in Korea, plan to continue it — and tell the clinic that at consultation so the plan can account for it.
Frequently asked questions
No. The laser fragments the ink; your immune system then clears the fragments over weeks, and only a portion of the ink is fragmented at each pass. Multiple sessions spaced six to eight weeks or more apart are required, and the number depends on ink colour, depth, density, age of the tattoo and how well the area's lymphatic drainage works. Anyone offering single-session removal of an established tattoo is not describing how the mechanism works.
Yes, but colours differ substantially in how they respond. Black and dark grey generally clear well. Red and orange usually respond to 532nm. Green and blue are treatable with 755nm and 1064nm. Purple, light blue and yellow are the most resistant and should be expected to need more sessions with less complete clearance. A realistic assessment of your specific colours comes after examining the tattoo, not from a colour chart.
It can be treated, but it is approached far more cautiously than a tattoo — because cosmetic pigments frequently contain compounds that can darken rather than fade under laser energy. Peach, flesh-toned and white pigments carry the highest risk. A test spot is performed first and assessed before treating the whole area. If you know what pigment was used, bring that information; it genuinely affects the plan.
Scarring is possible, and it is primarily a function of energy and interval rather than bad luck — which is why the protocol here is deliberately conservative. Existing scarring from the original tattooing process can also become more apparent as ink clears. Fine crusting and occasional blistering after a session are expected and settle; picking at them is what turns an expected reaction into a scar.
It is generally described as more uncomfortable than being tattooed — a rapid snapping sensation, sharper than laser hair removal. It is brief, and the treated area is short. Cooling is used, and how the session is managed for comfort is discussed at consultation. Areas over bone and thin skin are more sensitive than fleshy areas.
No, and this is worth stating plainly. Products sold as tattoo removal creams cannot reach ink sitting in the dermis — topical products do not penetrate to that depth. What some of them do achieve is chemical injury to the skin above the ink, which risks scarring and pigment change while leaving the tattoo where it is. The same applies to salt abrasion and other home methods. The outcome is a scarred tattoo rather than no tattoo.
