Tegaderm is a sterile, breathable, waterproof, and germ-proof barrier to protect your new tattoo. Leave the Tegaderm on for 3-4 days. Do NOT lift it, change it, or remove it.
The Tegaderm will protect your tattoo from infection, abrasion, irritation, and contamination while it is going through the most important part of its healing. It will also protect your clothes, sheets, and loved ones from coming into contact with excess ink, blood, and fluid that are the normal by-products of healing a tattoo.
You can perform all your usual activities (including exercise) while the tattoo is covered with Tegaderm. Be sure not to rub your new tattoo excessively, or do anything vigorous that will scrape or peel the covering off.
Showering will not affect the Tegaderm; it is reasonably waterproof. You can shower normally while healing, however, do not bathe or swim until your tattoo is fully healed.
After 3-4 days, remove the Tegaderm by carefully peeling it off of your skin. Do NOT quickly tear it off, as this can cause skin irritation. The easiest way to soften the adhesive is to stand in a hot shower for several minutes and remove the covering in the shower.
After removing the covering, rinse the tattoo thoroughly with warm water and wash, then rinse several times using antibacterial soap and warm water. Gently work any excess material off the surface of your skin using the palm of your hand while doing so. Do not use any washcloths, sponges, exfoliators, or brushes.
After patting your tattoo with a clean towel, the skin should be shiny and dry. Apply a thin layer of unscented, colorless lotion for the next 7-10 days a few times a day or as needed (I recommend Eucerin, Aveeno, CeraVe, or Lubriderm).
