What is HS (Hidradenitis Suppurativa)?

Put plainly, HS (Hidradenitis Suppurativa) is an immune disease that causes recurring boils in the folds of your skin. Usually, that means your armpits, groin, stomach, or buttocks. It’s also known as ‘acne inversa.’ It might be painful, it might be embarrassing, and it might be emotional. But...

  • It is NOT contagious.
  • It is NOT an infection.
  • It is NOT a result of poor hygiene.


People all over the world are living with HS. Some groups are more affected than others.

  • Sex: Women are 3x more likely to get HS than men.
  • Race: People who are Black or biracial are more likely to have HS than Caucasian people.
