The recommended instructions are to apply at the finish of the tattoo and leave on for 24 hours. This will fill up with plasma. At the 24 hour mark, remove and wash the tattoo.
Once dry, apply a second piece that will stay on for up to 6 days for a total healing time of 7 days.If the tattoo weeps into the second piece of film, follow the above instructions at the next 24 hour period and apply a 3rd piece.
The third piece would then stay on for 5 days. You can change the film as early as 8 hours into wear, though, if the tattoo is heavily weeping.
