How to say "acne" in Japanese

• にきびJLPT N1approx.Common
  nounThe word for pimples and for acne as a skin condition; normally written in kana. Use it when the topic is acne itself rather than skin trouble in general.
  ニキビが治なおりません。↗

  I can't get rid of my pimples.
• 吹き出物ふきでものCommon
  nounA broader term for skin eruptions, rashes, pimples and spots. It can cover acne, but it is really a general word for blemishes breaking out on the skin, not a specific name for the condition.
  暑あつい季節きせつには息子むすこの皮膚ひふに吹き出物ふきでものがでやすい。↗

  During the hot season, my son's skin breaks out easily.

For acne as a skin condition, 「にきび」 is the direct match; 「吹き出物」 is broader, covering skin eruptions, rashes, pimples and spots, so it suits such blemishes in general rather than acne specifically.
