An armpit rash, also known as axillary dermatitis or underarm rash, refers to the redness, irritation, and inflammation that can occur in the skin of the armpit area. It can be caused by a variety of factors, and understanding the underlying cause is essential for effective treatment.

10 Common Causes of Armpit Rashes

  • Friction: Skin-to-skin friction or friction from clothing, especially tight or rough fabrics, can lead to irritation.
  • Heat and Sweat: Excessive sweating in hot and humid conditions creates an ideal environment for rashes to develop.
  • Deodorants and Antiperspirants: Some ingredients in these products, such as fragrances or alcohol, can irritate the skin.
  • Allergies: Allergic reactions to fabrics, laundry detergents, or skincare products can cause rashes.
  • Fungal Infections: Fungi, particularly Candida, thrive in warm, moist environments, making the armpits susceptible to infections.
  • Bacterial Infections: Bacterial overgrowth, often due to poor hygiene, can result in painful rashes.
  • Contact Dermatitis: Skin reactions to allergens or irritants like poison ivy or nickel can lead to rashes.
  • Eczema: Atopic dermatitis, a type of eczema, can affect the armpits, causing redness, itching, and inflammation.
