It is generally recommended to wait at least 2 to 4 weeks before going swimming after getting a tattoo. This waiting period allows the outermost layer of the skin to heal sufficiently and reduces the risk of infection and damage to the tattoo. Your tattoo should be fully healed, with no scabs, redness, itching, or peeling before swimming. Chlorinated water in pools and natural water bodies like lakes or the sea can introduce bacteria and chemicals that may harm the healing tattoo. Always check with your tattoo artist for personalized advice and ensure your tattoo feels smooth and completely healed before submerging it in water.
