Wet Wrap Therapy

Wet wrap therapy (WWT) uses two layers of fabric over freshly moisturised or medicated skin: a damp cotton layer next to the skin and a dry layer on top. It is a treatment for severe flares of Atopic Dermatitis, especially when itch or pain is stopping a child sleeping. The National Eczema Association (NEA) describes it as part of an evening routine. First comes a Soak and Seal: a 5–10 minute lukewarm bath, gentle fragrance-free cleanser, pat the skin until it is just damp, apply prescribed medicine to affected areas, and moisturiser to the rest within three minutes. Then cotton dressings or clothing are dampened in warm water, wrapped over the affected areas, covered with a dry layer and pyjamas, and left on for two hours or overnight. Cotton gloves or socks can be used for hands and feet; wraps on the face should only be done as shown by a clinician. Here water works as a delivery vehicle: it cools and calms itch, rehydrates the stratum corneum, and the damp occlusion helps Emollient Therapy and Topical Corticosteroids penetrate.

Evidence: helpful in practice, weak in trials. The only meta-analysis, González-López et al. (Br J Dermatol 2017), found six RCTs that compared WWT plus topical steroids with topical steroids alone in children or adults. They were small (19–51 patients each), and results on severity and quality of life were reported incompletely and were inconsistent. The overall quality of evidence was low, and the authors concluded “the evidence that WWT is more effective than conventional treatment with topical steroids in AD is of low quality”. The 2022 Cochrane review of TCS strategies (Lax et al.) looked for trials of steroid cream used with wet wraps, but listed it only among “other comparisons” with too little data to draw a conclusion. Supportive data come mostly from uncontrolled programmes. The NEA cites Nicol et al. (J Allergy Clin Immunol Pract 2014), where children with moderate to severe eczema in a multidisciplinary programme had an average 71% reduction in symptoms that held a month later. The 2023 American Academy of Dermatology guideline on topical therapies (adults) gives wet wraps a conditional recommendation.

Conflict: [National Eczema Association, 2025] says wet wraps can help topical medicines work better and cites a 71% average reduction in symptoms in children with severe eczema (Nicol 2014, uncontrolled). [González-López et al., Br J Dermatol, 2017] says evidence that WWT beats topical steroids alone is of low quality, with heterogeneous results across six small RCTs.

Use with topical steroids and NICE advice. Occlusion increases steroid penetration several-fold, which is why wet wraps work and also why they carry risk (Topical Corticosteroids). NICE CG57 (children under 12) says: do not use whole-body (limbs and trunk) occlusive dressings, including wet wraps, or whole-body dry bandages as first-line treatment; if they are used, a healthcare professional trained in their use should start them. When whole-body wraps are combined with TCS, use them for 7 to 14 days at first, get specialist advice before continuing, and consider stopping the steroid and carrying on with wraps over emollient alone until the eczema is controlled. Localised medicated dressings or dry bandages with emollients (with or without TCS for 7–14 days) can be considered for flares or thickened, lichenified patches. NICE also says not to use Topical Calcineurin Inhibitors under bandages or dressings in children without specialist advice, and not to use occlusive dressings on infected eczema.

Infection and steroid over-absorption under wraps

In the 2017 meta-analysis, children and adults treated with wet wraps had a non-significant trend toward more mild skin infections (pooled RR 6.35, 95% CI 0.83–48.55). Do not wrap weeping, crusted or suspected Infected Eczema, and get the child seen urgently if they develop punched-out sores or fever (Eczema Herpeticum). Because wraps boost absorption, only use the steroid strength and duration prescribed: NICE limits whole-body wraps with TCS to 7–14 days without specialist advice.

Toddler safety. The main risks are skin infection, Folliculitis (blocked, inflamed hair follicles from too much ointment under prolonged covering; the NEA advises stopping until the bumps clear), and more systemic steroid exposure with long or whole-body use. Damp layers can also chill a small child, so the room should be warm and the dry outer layer and pyjamas should cover the wet one. Wraps are labour-intensive and some toddlers will not tolerate them; NICE’s requirement for a trained professional to start them reflects how easy they are to get wrong at home.

What parents report (evidence: anecdotal). On Reddit, parents of toddlers describe overnight wet wraps after bath, cream and petroleum jelly as the step that brought a bad flare under control: “Wet wraps and bleach baths saved us!” (r/beyondthebump), and “my second kid actually needed full-body wet wraps for a bit” (r/toddlers). A simpler home version, “basically wet pjs for 15-20 min”, then petroleum jelly and dry pyjamas, was suggested by one family’s paediatric dermatologist (r/SkincareAddiction). Another parent, whose toddler reacted to every bleach bath dilution, said “wet wraps worked better for us” (r/eczema). Parents also use wraps and sleeves at naps and night to limit scratching.
