Skin

Skin is a layer of tissue that covers the body of most living beings, offering containment and protection for their internal organs. In mainstream Smurfs media, Smurf skin is normally blue, though the shade of blue tends to vary with the visual media. It can turn other colors depending on various conditions, though they are mostly magical in nature. Like humans, Smurfs can suffer the condition of sunburn, where their skin turns literally red from too much exposure to the sun without any form of protection. There are other types of skin diseases that are native to the media the Smurfs appear in.
