Wear clothing that does not come in contact with the airbrush tattoo to avoid rubbing the paint off.
Avoid oil or alcohol-based products in the area that has the airbrush tattoo. Cover the tattoo with a water-resistant bandage while in the shower or swimming. Pat the tattoo dry instead of rubbing the skin.
Cover the tattoo with baby powder. Use a makeup brush to dust baby powder over the tattoo and the surrounding skin to help seal the design from oils from your skin. Blot any sweat or water off of the tattoo before applying the baby powder to avoid forming a paste.
