Wet wrap treatments are often helpful. This involves dampening the skin with lukewarm water until it is well hydrated (usually 10 min). Then, petrolatum or steroid ointment is applied liberally, followed by occlusion for 1 hour with damp pajamas or a nonbreathable sauna suit. For small areas of involvement, plastic wrap may be used to occlude the area. This process may be repeated 5-6 times a day with petrolatum. Caution must be used when prescription steroid medications are used because overuse of these medications can cause striae, thinning of the skin, and, rarely, enough systemic absorption of steroid to affect the hypothalamic-pituitary-adrenal axis.
