The tatourelle should be applied right before bed for best results.

1- Prepare your skin by shaving and exfoliating.  Make sure the skin is dry and free of any skin care products (moisturizers and sunscreen).

2- Peel off the release liner to expose the sticky surface of the tatourelle applicator.

3- Place the sticky part on the skin.  Once the sticker is on the skin it shouldn't be moved.  Avoid placing the tatourelle on a part of the body that emits excessive sweat or oil.  Avoid placing the tatourelle on an area of the body that bends frequently, like a joint.

4- Apply the second-skin breathable adhesive layer over top of the tatourelle applicator to reinforce it while you are sleeping. Be careful not to bend the applicator when it's on the skin as this will affect the image transfer.  It's impossible to stay perfectly still while you are sleeping; the second-skin layer should help hold the tatourelle in place during small movements. 

5-Do not get the applicator wet and try not to sweat while the applicator is on the skin- this will also mess with the image transfer.  It's important to sleep in a cool, dry place.

6- Peel off the applicator and second-skin in the morning - it will feel a bit like ripping off a bandaid!  Your tatourelle should be visible.  It is now fully waterproof and sweat-proof.

7- Tatourelles last a week or two... that depends on you.  To preserve it, avoid scrubbing it in the shower or exfoliating the area with a towel.  If you want to remove your tatourelle, exfoliating the area will likely make it go away in 4-5 days.
