If you just got a tattoo, one of the first things any reputable tattoo artist will tell you is how crucial aftercare is. "A tattoo takes approximately four to six weeks to completely heal, and one of the biggest mistakes you can make after getting a tattoo is to let it dry up," says Shari Marchbein, MD, a board-certified dermatologist based in New York City. If you just stepped out of the tattoo studio, your next step is to grab one of the best tattoo aftercare products on the market to soothe, nourish, and moisturize the skin while maintaining color vibrancy.
