What to Know Before Removing a Large Tattoo

Removing large tattoos is not a simple procedure; it's a long journey with your skin. The larger the area, the greater the risk of side effects and pain. However, if you understand the principles well, you can reduce skin concerns and gradually remove the tattoo. Today, we will summarize four essential things you should know before undergoing large tattoo removal.

Firing the laser too frequently does not make the tattoo disappear faster. This is because after the laser breaks down tattoo particles, it takes time for our body to expel and absorb those particles.

Therefore, it is important to break down the particles at appropriate intervals rather than too often. If the laser is fired too frequently, repeated damage can occur to the surrounding area during the particle breakdown process, and that area may turn into scar tissue.

Just as getting a tattoo is painful, removing it also involves pain. This is because tattoo particles, when hit by the laser and broken down, can irritate surrounding tissues and nerves.

Ultimately, pain is a sensation produced by nerves, so it can be controlled by various methods that dull nerve sensation. For example, if the treatment area is cooled, pain is reduced because the nerves that sense cooling and the nerves that sense pain use the same pathway. If the tattoo is not too severe, the procedure may even be performed without anesthesia.

Blisters can form after laser tattoo removal. Usually, small blisters appear, and even if large blisters form, there is no need to be overly concerned. However, if the blisters are too large, the following points should be noted:

• First, if they are large, management itself is difficult.
• Second, secondary bacterial infections can occur.
• Third, there is a higher possibility of scarring due to damage to surrounding tissues.

Therefore, if large blisters form, it is best to visit the clinic immediately for management. These blisters are completely different from burns caused by other lasers. This is because tattoo removal lasers deliver concentrated energy in a very short time. It's the same principle as quickly passing your hand over a candle flame without getting burned. The PicoWay Laser, which has recently become the standard, delivers energy in an even shorter time, so blisters may be larger and more common, but this does not significantly affect the outcome.

After removing color tattoos, the skin may appear slightly whiter than the surrounding area, more so than with black and white tattoos. This is different from vitiligo.

Vitiligo is a disease where melanin-producing cells that determine skin color are attacked and die, but the whitish appearance in the area of a color tattoo is a temporary hypopigmentation phenomenon that occurs when scabs form and fall off. However, since the color contrast with the surrounding area may be noticeable, it is advisable to consistently use moisturizers and sunscreen overall.

When removing large tattoos, the faster you try to finish, the greater the risk of scarring and pigment changes. By approaching it calmly with an understanding of appropriate intervals, pain control, blister management, and pigment changes, you can reduce the burden on your skin and remove the tattoo.

If you are concerned about a large tattoo, we recommend setting up intervals and a plan that suits your skin condition rather than simply increasing the number of sessions.
