No. Do not apply anything under or over the second skin.

I apply the bandage myself over clean, completely dry skin. As long as the second skin stays properly sealed, the tattoo does not need any additional care underneath it.

Do not apply moisturizer, cream, ointment, or any other product on top of or underneath the bandage. Just keep an eye on the seal and follow the removal instructions if it starts leaking, lifting, or opening.
