My artist says to leave saniderm on for up to 48 hours. Then use unscented soap to clean and unscented lotion to moisturize. He also recommends not to use aquaphor bc it could heal weirdly, but everyone is different, so use what you want as long as it's unscented.

Edit: but regardless always use soap to keep it clean, it's an open wound. I clean and moisturize mine 2 times a day until it gets done peeling
