Dry skin under the breast can be caused by a lack of moisture in the skin. To treat or prevent dry, rough, scaly, itchy skin, moisturizers can be used. Here are some details on products, ingredients, and materials that can help with dry skin under the breast:

Moisturizers

• Look for a moisturizer that lists glycerin as the first ingredient. It will help your skin hold on to moisture and prevent future dryness.
• Emollients/moisturizers work by forming an oily layer on the top of the skin that traps water in the skin. Petrolatum, lanolin, mineral oil, and dimethicone are common emollients.
• Colloidal oatmeal is a moisturizer that can be used to treat or prevent dry, rough, scaly, itchy skin and minor skin irritations.

Ingredients and materials

• Avoid ingredients that dry your skin, such as isopropyl alcohol, benzyl alcohol, or sulfates.
• Look for ingredients that lock in moisture like petroleum jelly, hyaluronic acid, lanolin, or mineral oils (emollients) .
• Look for ingredients that attract moisture, like glycerin.
• Some products (such as zinc oxide, white petrolatum) are used mostly to protect the skin against irritation (such as from wetness) .
• The most inert natural hypoallergenic product that you can find in a moisturizer is petrolatum.

It is important to note that breast eczema can also cause dry skin, discoloration, and itchiness on the breasts. If you have severe dry skin or breast eczema, you should see a doctor for treatment.
