The duration for keeping the protective material on depends on the type used. If a medical polyurethane film (dermal bandage) was applied, it should usually remain for 12-24 hours; if traditional plastic wrap was used, this period is 2-3 hours. Once removed, the tattoo must be gently washed using antibacterial soap and drinking water.
Why?
Tattooing involves placing ink into the lower layer of the skin by passing through the upper layer, which the body sees as a 'fresh wound.' During the first 24 hours, the body produces a fluid rich in plasma and immune cells to stop bleeding and protect the area from germs. Protective bandages work by keeping the wound slightly moist, which helps cells repair faster, prevents infections, and avoids heavy scabbing.
