Question

Eczema bleach bath: Can it improve my symptoms?

What is a bleach bath? Can it treat chronic eczema symptoms?

Answer

from Lawrence E. Gibson, M.D.

An eczema bleach bath — a bath with a small amount of bleach added to the water — may help lessen symptoms of chronic eczema (atopic dermatitis). Eczema is an itchy skin condition that's most often seen in infants and children, but it can continue into adulthood or first appear later in life.

A bacterial infection often accompanies eczema and can worsen symptoms. An eczema bleach bath is thought to kill bacteria that grow on the skin, which reduces itching, redness, scaling and other symptoms of eczema. An eczema bleach bath is most effective when combined with other eczema treatments, such as medication and daily moisturizers.

If properly diluted and used as directed, a bleach bath is safe for both children and adults. For best results:

  • Add 1/2 cup (118 milliliters) of bleach to a 40-gallon (151-liter) bathtub filled with warm water.
  • Soak the affected areas of skin for at least five to 10 minutes.
  • Dry your skin thoroughly and apply a thick layer of moisturizer.
  • Take a bleach bath no more than twice a week.

Though some people experience positive results, a bleach bath can cause skin dryness if the bleach concentration is too high or if the bath is done too often. If your skin is cracked or extremely dry, any bath — including a bleach bath — may be painful. Talk to your doctor before trying an eczema bleach bath.
