Moisturize: Keep your tattoo moisturized to prevent scabs from forming. Using an unscented lotion apply a thin layer one to two times a day for the duration of the healing period (which can take anywhere from 2 - 4 weeks) A thin layer of skin will start to peel off like a sunburn. It's normal to see some flakes of coloured skin fall off. DO NOT PICK OR SCRATCH THIS OFF. Let it fall off naturally. 

Avoid soaking: Don't fully submerge your tattoo in water for at least two weeks. Don't go swimming or use a hot tub. 

Avoid abrasive materials: Don't wear jewelry, shoes, clothing, or other abrasive materials that rub against your tattoo. 

Wash hands: Don't let anyone touch your tattoo unless they've washed their hands (and only if they are helping you moisturize in an area you yourself cannot reach)

Wash gym equipment: Wash gym equipment well before using it.

After you take your bandage off KEEP IT CLEAN: Clean your tattoo to remove excess blood, plasma, or ink. Use an unscented soap to wash it first with warm water (lather wash and rinse, just with your hand, not a facecloth or anything) and then back to back with cold water (lather wash and rinse). Warm water gets off any extra blood or plasma. It's normal for a tattoo to bleed after getting it. Cold water cools your skin down. 

Pat dry or let air dry and then apply your first THIN layer of an unscented lotion, tattoo ointment, etc. This usually goes on 1 - 2 times daily throughout the duration of the healing period. 

Avoid picking: Don't pick, scratch, peel, rub, or irritate your tattoo. Scratching can lead to scarring. If you absolutely HAVE to slap it with clean hands (how technical right? lol)

Protect from the sun: Avoid direct sunlight for at least two to four weeks. UV rays can cause sunburn or make it fade. When you can go outside, wear loose-fitting clothing and stay in the shade. Once your tattoo is healed, use sunscreen regularly to protect it. 

Hydrate: Drink lots of water to keep your skin healthy and your tattoo vivid.
