Abstract
Abstract The healing of a number of skin disorders is effectively enhanced by prolonged continuous occlusion and/or hydration. Treating these disorders, e.g. psoriasis, is significantly facilitated by occluding affected skin areas with a suitable barrier for a prolonged and continuous period of time. Such occlusion is effective by itself, but is materially improved by concurrent topical administration of medicament useful for treating the disorder. In such cases the prolonged, continuous occlusion markedly increases hydration which has the further therapeutic benefit of tremendously facilitating penetration of medicament. The provided barrier is advantageously one with low vapor transmission or one which is water impermeable.
