Can eczema be treated without medication?

Protect. Avoid things that make you break out, soaps & wetness. Wash your hands only when necessary. Wear gloves when needed. Wear clothes made of cotton. Bathe only with a small amount of mild unscented soap, such as dove. Keep the water temperature cool or warm, not hot. Use the medicine your doctor gave you. Use a plain moisturizer daily. Avoid scratching or rubbing the itchy area. Manage stress.
Sometimes. Mild eczema can be treated without daily medication. Eczema is called the "itch that rashes" not the rash that itches. Controlling itching eliminates scratching & permits the skin to heal. Start with daily bathing not showering. Soak for 10-15 minutes. Use cetaphil or cerave cleanser. Then moisturize the entire body with an unscented cream, ointment, or petroleum jelly. Use a lot. Avoid lotions.
Yes. Partially. Eczema often involves dry skin. Gentle skin care is very important. Use mild skin cleansers, moisturize immediately after bathing using a high quality lotion or cream, and avoid using products with fragrances or dyes.
