With saniderm /second skin:
leave on for max of 3-5 days. If redness or irritation appears, remove, if seal is broken, remove, if you sweat excessively in it or notice large amounts of pooling remove.
in order to take it off lift a bottom corner and pull down and out, ideally in the shower as the steam will weaken the seal.
after saniderm/second skin or without saniderm:
wash with unscented antibacterial soap, let air dry. Apply light layer of unscented moisturizer. Repeat 2-3 times daily
if you choose to use something petroleum based be extra cautions to use light layers.
