We receive many questions about tattoo removal through various channels. We've selected the most frequent ones and compiled the answers.
Two Variables in Tattoo Removal Time
The principle of tattoo removal is that a laser breaks down the ink into the smallest possible particles, and then immune cells, such as macrophages, transport that ink away.
While there are many variables, two are largely important:
- How well the tattoo ink is broken down
- How well the broken ink is transported, i.e., the activity of immune cells
With the PFD special medication, up to 4 treatments are possible at once, making it more effective than traditional methods. You can find the details in the R-Zero Pico-Frectat Tattoo Removal guide.
Will Multiple Treatments Cause Scars?
Scars from laser removal do not occur from repeated treatments.
Scars occur when treatment is performed excessively in an attempt to achieve an exaggerated effect in a single session. They can also occur in individuals with a skin type prone to scarring.
Yonsei Star Dermatology Sinchon is a clinic specializing in scar treatment, so we have expertise in scar prevention. Our prevention methods are outlined in the Pinhole for Burn & Surgical Scar treatment guide.
Is the R-Zero Pinhole Technique Used for Eyeliner?
Theoretically, it is possible. However, the eyes are a vital organ in our body. While the possibility of special medication entering the eye and causing problems is very low, we prefer to avoid that possibility altogether.

| Eyebrow Tattoo | Applied |
| Eyeliner Tattoo | Not Applied |
Can You Tell the Number of Sessions Just by Looking at a Tattoo?
It is difficult to know precisely. The number of sessions varies depending on the amount of pigment and the colors mixed to achieve the final color, which is not always apparent. Like the depth of a lake that cannot be known just by looking at the surface, it is difficult to accurately determine the amount and depth of pigment with the naked eye.
The activity of immune cells also varies from person to person, making it hard to predict the exact number of sessions. However, it is true that tattoos with darker or more mixed colors, and those located further down the legs, generally require more treatment sessions.
Do Painkillers Eliminate the Pain?
The pain experienced during tattoo removal is slightly different from typical pain. It is a physical pain caused by the tattoo ink bursting within the skin.
While painkillers can reduce chemically perceived pain, they cannot fully block the tearing sensation in the skin. However, if you experience fever and mild pain on the evening of the procedure, painkillers can be effective, so it is acceptable to take some. If the pain is too severe, please visit the clinic where you received treatment.
Can a Full Body Tattoo Be Removed in One Day?
Treating a large area in one day can be excessive. If you wish to remove a full body tattoo, we recommend receiving treatment in separate sessions.
After the procedure, complications such as bacterial infection can occur, making post-treatment care crucial. Treating a large area makes this care proportionally more challenging.
Can I Use a Hydrocolloid Dressing?
Generally, it is better not to apply a hydrocolloid dressing after tattoo removal.
When tattoo particles are broken down into small pieces, some particles drain out with exudate. A hydrocolloid dressing can hinder this process, which may slow down the tattoo removal speed. We recommend managing the area by applying ointment instead of a hydrocolloid dressing.
