Pros of Baking Soda

    Baking soda is not a cure for eczema, but it may help relieve the itch associated with it. 

    Baking soda has anti-inflammatory and antibacterial properties. It can dry out your skin due to its alkaline properties, so you can get relief from itching and swelling that comes with skin rashes.

    Cons of Baking Soda

    Skin is meant to be slightly acidic, with a pH between 4.5 and 5.5, but baking soda has a pH of 9. Increasing the pH of your skin can lead to dryness, irritation, and other side effects. Baking soda's alkalinity also makes it too basic of a solution to use as a face wash.

    Baking soda may cause skin irritation for some people. Most people do not know they have a baking soda allergy until they use a deodorant with baking soda or apply a baking soda paste on a bug bite or eczema bump.
