Use warm, not hot, water for at least 10 to 15 minutes. Avoid scrubbing your skin with a washcloth.
(within three minutes of taking a bath or shower), apply any special skin medications prescribed for you and then liberally apply a moisturizer. This will seal in the water and make the skin less dry and itchy.
The most common skin medications used to treat skin inflammation are prescription and non-prescription topical steroids or prescription topical calcineurin inhibitors (TCIs). Be sure to use these medications as directed. Remember that TCIs can sting if applied to wet skin, so apply a thin coat to affected areas only.
Specific occlusives or moisturizers may be individually recommended for you.
Creams and ointments are more beneficial than lotions. Petroleum jelly is a good occlusive preparation to seal in the water; however, since it contains no water it works best after a soaking bath.
DO NOT completely dry your skin after your shower or bath. Instead, pat yourself lightly with a towel if needed.
