Tattoo removal is often done as an outpatient procedure with local anesthesia. Common techniques for tattoo removal include laser surgery, surgical removal and dermabrasion.
Laser surgery
Q-switched lasers — which release energy in a single, powerful pulse — are often the treatment of choice for tattoo removal. A special type of laser — called a Q-switched Nd:YAG — might be used on darker skin to avoid changing the skin's pigment permanently.
Before laser treatment, the skin is numbed with an injection of a local anesthetic. Then a powerful pulse of energy is applied to the tattoo to heat and shatter the tattoo ink. Multicolored tattoos might need treatment with various lasers and different wavelengths.
After the procedure, you might notice swelling and possibly blistering or bleeding. Antibacterial ointment can help promote healing. You'll likely need repeated sessions to lighten the tattoo, and it might not be possible to completely erase the tattoo.
Surgical removal
During surgical removal, the skin is numbed with an injection of a local anesthetic. The tattoo is removed with a scalpel, and the edges of skin are stitched back together. After the procedure, antibacterial ointment helps promote healing.
Surgical tattoo removal is effective — but it leaves a scar and might be practical only for small tattoos.
Dermabrasion
During dermabrasion, the tattooed area is typically chilled until numb. Then the tattooed skin is sanded down to deeper levels with a high-speed rotary device that has an abrasive wheel or brush. This allows the tattoo ink to leach out of the skin.
The affected area feels sore and raw for several days after the procedure. Recovery can take up to two to three weeks. Due to unpredictable results and less effective outcomes than laser or a combination of laser and excision, dermabrasion isn't a common choice.
