Application of a cold compress

Topical drying agents

Baking soda or oatmeal can be combined with water to produce a paste which helps dry the skin and lessen the itchiness. The paste is placed on the site and left to air dry. Both can be added to a cool, tepid bath for relief to the itchiness.

Other drying agents include Burow’s solution and witch hazel but might cause a stinging sensation if applied on the blistered skin.
