Gently wash your new tattoo with lukewarm water and fragrance-free  soap twice a day for the first week.  Pat dry and apply recommended ointment or fragrance-free  lotion. 

Avoid direct sun exposure, large bodies of water, and excessive sweating for the first 2 weeks to prevent irritation and to allow the tattoo to heal properly.

Contact a medical profession if you begin to experience signs of an infection such as swelling, redness, irritation, or pus.
