You go down a slide made of branches and your skin scrapes right off — ouch! Lucky for you, it was just your old outer layer of skin, and now you've got a fresh shiny layer. Yay for exfoliation! You're not sure what to do with this big, floppy layer of old skin, though…

Without your rough old skin to protect you, you feel the full heat (ひ) of the sun now. It burns… it burns! Yeah, you better protect that fresh new skin from the heat.
