Common treatments for dry skin rashes include changing cleansing products, using an emollient or applying a topical steroid, according to DermNet. WebMD also suggests wearing gloves, taking flaxseed oil and using oatmeal to ease inflammation.
As DermNet explains, soap is typically drying to skin and should therefore be replaced with a synthetic cleanser or bath oil. WebMD points out that common hand sanitizers are also very drying and should be replaced with hydrating versions of the product.
Emollients can add moisture to dry skin. WebMD suggests using petroleum jelly, which is gentle to the skin and can be used on all parts of the body. Damaged and dry skin is likely to respond better to petroleum jelly than to commercial moisturizers, which are typically laden with potentially irritating chemicals. Wearing gloves when handling cleaning products helps protect the hands from the skin irritants typically present in these products. WebMD also suggests taking an oatmeal bath to take advantage of the chemicals in oatmeal that reduce skin inflammation.
When dry skin is caused by atopic eczema, also known as dermatitis, it's often necessary to treat it with a topical corticosteroid cream or ointment, according to WebMD. Over-the-counter products that contain hydrocortisone can ease eczema's itching, redness and swelling. Severe cases may require cortisone shots or prescription-strength pills.
