Hydrocolloid dressings are supported by scientific evidence for use in managing eczema, particularly in the context of wet or weeping lesions and as a support for healing skin barrier disruption. Hydrocolloid dressings are occlusive or semi-occlusive wound coverings composed of gel-forming agents. In eczema care, especially in cases of severe atopic dermatitis with erosions or excoriations, hydrocolloids can help maintain a moist wound environment, which is conducive to healing. They also serve as a protective barrier, reducing trauma from scratching, decreasing transepidermal water loss, and protecting against external irritants and infection.

Several studies and case series, primarily in pediatric populations, have demonstrated that hydrocolloid dressings can accelerate healing and provide symptomatic relief in both acute and chronic eczematous lesions. Randomized controlled trials are limited, but the available research suggests that hydrocolloid dressings may be superior to standard gauze in terms of healing time, reduction of pain and pruritus, and patient satisfaction. Their use is also recommended in some clinical guidelines as a part of wound care strategies for eczema with secondary infection or persistent erosions. However, hydrocolloids are not a primary therapy for the underlying inflammatory process of eczema and should not replace topical corticosteroids or other cornerstone therapies.

Overall, while the evidence base is not robust and more high-quality trials are needed, there is moderate scientific validation for the adjunctive use of hydrocolloid dressings in managing specific manifestations of eczema.
