What are the types of armpit rash?

  • Contact dermatitis – this skin reaction occurs if exposed to an irritant or allergen.
  • Atopic dermatitis – this generally starts in childhood and likely to form in the body folds such as the back of the knee, interior of the elbows or armpits. It is typically itchy, red and crust over.
  • Seborrheic dermatitis – this is a form of skin irritation triggered partly by excess production of sebum. It manifests as oily patches of scales or flakes that are white or yellow in appearance.
  • Candida – this is a fungus or yeast infection that typically affects moist areas including the armpits.

An armpit rash can be managed with ingredients at home such as:

  • Apply an ice pack against the rash to lessen the itchiness.

  • Coconut, lavender or tea tree oil can reduce the irritation and itchiness as well as deal with fungal infections.

Calamine lotion and hydrocortisone cream are both effective as home treatment for an armpit rash that triggers inflammation and irritation.

For a candida rash or other form of fungal rash, the management includes over-the-counter anti-fungal treatments containing clotrimazole, ketoconazole or nystatin.
