This is a guide to PicoSure tattoo removal compiled by Dr. Choi Byeong-geun of SHINE U Clinic Konkuk (3 minutes walk from Konkuk Univ. Station Exit 1).
Many people think that small tattoos are easy to remove, but tattoos, regardless of size, are more difficult to erase. To understand the difference, it's necessary to look at the laser's pulse duration. In this article, we compare picosecond and nanosecond units to explain the removal principle.
Why Even Small Tattoos Are Tricky
More important than size is the state of the pigment.
- The color, size, type of pigment, and depth vary from person to person.
- Removing a tattoo is a more delicate process than getting one.
- Therefore, even mini tattoos require a cautious approach.
The Picosecond Unit
The key to a laser is its pulse duration.
1 millisecond is 0.001 seconds, 1 nanosecond is 0.000000001 seconds, and 1 picosecond is 0.000000000001 seconds. The shorter the unit, the greater the power concentrated in an instant.
- Conventional lasers typically operated in the 2-40 nanosecond range.
- Pico lasers are shorter, around 450-750 picoseconds.
- This is 3 to 10 times shorter than conventional lasers.
Why Short Pulse Duration is Important
A shorter pulse duration is more advantageous for breaking down pigments.
- High energy is concentrated and delivered in a short instant.
- It helps break down ink into finer particles for faster expulsion.
- It targets pigments deep within the pores.
Advantages Compared to Nanoseconds
Pico lasers differ from conventional methods.
| Item | Nanosecond Laser | Pico Laser |
|---|---|---|
| Pulse Duration | Longer, accumulates irritation | Shorter, less irritation |
| Pigment Breakdown | Relatively coarse | Breaks down into finer particles |
| Number of Sessions | Tends to be more | Reported to be fewer |
- It tends to cause fewer blisters and inflammation by minimizing damage to surrounding tissues.
- It selectively targets ink and melanin particles.
- However, results and the number of sessions may vary depending on the individual.

Also Used for Pigmentation Improvement
PicoSure is used for pigmentation improvement in addition to tattoos.
- It is utilized for improving stubborn and complex melasma, freckles, age spots, and blemishes.
- It can also help with managing pores, fine lines, and acne scars.
- For managing pigmented lesions, please refer to PicoSure Toning.
Precautions After Treatment
It is recommended to follow these guidelines after treatment.
- Refrain from alcohol and smoking due to the risk of inflammation.
- If scabs form, allow them to fall off naturally.
- Avoid jjimjilbangs (Korean saunas), saunas, and strenuous exercise, and visit the clinic if you experience any adverse reactions.
Tattoo removal can be performed regardless of the season. If you wish to reduce the burden with a laser that has a shorter pulse duration, please feel free to inquire about My Removal Plan.
