Tattoo removal is a process used to erase or lighten unwanted tattoos, most commonly done with lasers. Laser tattoo removal works by breaking down the ink particles in the skin so the body can naturally remove them over time. It usually takes several sessions, depending on the tattoo’s size, color, and age. Other methods include surgical excision, dermabrasion, and creams, but lasers are the safest and most effective option. Some redness or swelling may occur after treatment, but serious side effects are rare.
