Remember, your tattoo is an open wound while healing. If you expose your tattoo to unsanitary conditions, infection is possible! Clean clothes & bed sheets are important, and absolutely no baths/swimming pools until the tattoo is completely healed, which should take roughly 2 weeks. It may take a few weeks for your tattoo to settle while your skin repairs itself so you should avoid tanning, and use sunblock to protect your skin and your new tattoo.
Note: Aquaphor is a safe recommended ointment. Do not use alcohol, zinc-based products, or Neosporin. If you have questions about an alternative, please ask your artist.
