How to say "skin" in Japanese

Choosing the right word
  • 肌はだJLPT N3approx.Common
    nounThe skin of a person's body, especially as felt or seen — texture, complexion, bare skin. This is the everyday word when talking about someone's skin, such as skin that is smooth, dry, or sensitive.
    If it continues to be stimulated the skin's protective function causes thickening and it becomes stiff and hard with pores that stand out.
  • 皮かわJLPT N3approx.Common
    nounSkin as an outer layer, especially the hide or pelt of animals, or the peel of fruit. For human skin it is not the usual choice; 肌 or 皮膚 is what you want.
    動物どうぶつの皮かわは毛けでおおわれている。↗
    The skin of animals is covered with hair.
  • 皮膚ひふJLPT N2approx.Common
    nounSkin as the organ of the body — the anatomical or medical term. It is the word you meet in contexts like skin conditions, skin care, or dermatology, rather than in casual talk about how skin looks or feels.
    日光にっこうは皮膚ひふに作用さようする。↗
    The sunbeam acts upon the skin.
  • スキンCommon
    nounThe loanword, used mainly in set borrowed expressions and commercial contexts such as cosmetics. For ordinary reference to skin, a native word like 肌 is usually the better choice.
  • むくJLPT N2approx.Common
    godan verb, transitive verbA verb, not the noun: it means to peel or skin something, such as removing skin or a peel from fruit. It never serves as the noun 'skin' itself.
    このなしの皮かわをむくナイフを貸かして下ください。↗
    Lend me a knife with which to peel this pear.

Use 肌 for skin on the body, 皮膚 for skin as anatomy or in medical contexts, 皮 for animal hide or peel, 「スキン」 for loanword uses, and 「むく」 only for the verb 'to skin'.
