Tattoo artists have varied approaches to tattoo aftercare, however, some pro tips:
Do not use A&D ointment.
Moisturize your skin with unscented hand lotion.
Drink plenty of water, because water helps to maintain the elasticity of skin.
Avoid alcoholic beverages as they can cause dehydration, which would be the opposite of hydrating your skin.
Avoid using cocoa butter, and any lotions, soaps, or shower gels that have microbeads or fragrances of any kind.
No direct sun for two weeks. Do not apply sunscreen to the tattoo.
Take short showers and do not swim or saturate your new tattoo.
Do not scratch or pick at it whatsoever.
