Until the tattoo is fully healed, the area is vulnerable to the bacteria found in swimming pools and lakes. Waiting a minimum of two weeks to go swimming reduces the risk of irritation and infection, but if the tattoo has not completely healed, it is necessary to clean the area thoroughly after swimming.
