Modified dressings for inflammatory dermatoses
Modified dressings are dressings that are used to treat severe dermatitis. They include wet dressings, the ‘soak and smear’ technique and occlusive dressings. Choice may depend on condition present and patient preference.
Wet dressings and the ‘soak and smear’ technique increase hydration of the epidermis, increasing penetration of topical corticosteroids. They are particularly useful for:
- severe acute dermatitis
- thickened and lichenified skin
- discoid dermatitis.
Wet dressings and ‘soak and smear’ technique are usually used for a few days (7 to 10 days) with specialist guidance. The risk of systemic absorption from using a potent topical corticosteroid under a wet dressing or with the ‘soak and smear’ technique is not clinically significant.

Soak dressings in water that is a comfortable temperature
- for infants, use a jumpsuit as the dressing
- for older children and adults, use pyjamas, elasticated tubular bandages, towels, sheets, cotton socks (for feet) or cotton gloves (for hands) as the dressing
Take a bath or shower and lightly pat skin dry
Apply topical corticosteroid to affected skin
If the skin is particularly dry, apply a layer of bland greasy emollient after applying topical corticosteroid
Cover treated skin with damp (wrung-out) wet dressings
Wrap up in a towel or wear dry clothes on top of wet dressings, to keep warm and ensure the damp layer is in close contact with the skin
Remove the wet dressings after 15 to 60 minutes
Dry the skin, then apply an emollient

Soak in a warm bath of plain water for 20 minutes just before bedtime
Don’t dry skin after getting out of bath
Smear affected skin with large amounts of topical corticosteroid
Put on old pyjamas or loose clothes
Apply an emollient to the skin the following morning
Occlusion with an impermeable film increases absorption of a topical preparation and promotes skin rehydration. Occlusive dressings are particularly useful for:
- thick skin surfaces (eg palms and soles)
- hypertrophic skin conditions (eg nodular prurigo, hypertrophic lichen planus, hypertrophic scars).
Clean the skin and apply the topical preparation while the skin is damp. Cover affected skin overnight with a waterproof dressing or plastic film wrap. For fingers or toes, hypoallergenic adhesive tape can be used as an occlusive dressing.
Monitor for possible adverse effects of occlusion, including maceration, folliculitis and miliaria. Occlusion can potentiate adverse effects of topical corticosteroids (eg atrophy, telangiectasia) and should be used with caution in children.
