Should Emollients Be Recommended for the Prevention of Atopic Dermatitis?—New Evidence and Current State of Knowledge

Abstract

Introduction: Atopic dermatitis (AD) is a chronic, pruritic skin disease with complex pathogenesis, which affects about 43 million children aged 1–4 years. One of the most known methods of alleviating symptoms of AD is emollient treatment, which varies depending on formulation and additional active ingredients. There is some evidence that emollients could be used in AD prevention in high-risk children. Materials and methods: A search of the literature from Cochrane Library, PubMed and Medline was conducted between August and September 2023 with the following keywords: “atopic dermatitis”, “emollients”, and “prevention”. Only randomised clinical trials published in the last 5 years were included into the meta-analysis. Results: Considering the inclusion criteria only 11 randomized clinical trials were taken into account, and six of them proved lack of effect of emollients in the prevention of atopic dermatitis among neonates from AD risk groups. Conclusions: Emollient treatment has a good safety profile and most of the ingredients used in formulations are nonirritant for sensitive newborn and infant skin. There is some evidence of the positive effects of emollient treatment in prevention of AD in predisposed populations. The relatively high cost of emollient treatment (vs regular infant skin-care routine) would support the necessity for further evaluation of their effectiveness in nonpredisposed populations.
