Efficacy of Topical Application of a Skin Moisturizer Containing Pseudo-Ceramide and a Eucalyptus Leaf Extract on Atopic Dermatitis: A Review

Abstract

Atopic dermatitis (AD) is a chronic inflammatory skin disease associated with pruritus, an impaired cutaneous barrier function and a disrupted water holding capacity. Levels of ceramides, which are major components of intercellular lipids and are crucial for their functions, are decreased in the stratum corneum of patients with AD. Treatments to increase ceramide levels are effective for AD care. Synthetic pseudo-ceramide (cetyl PG hydroxyethyl palmitamide (SLE66)), which has a structure developed via molecular designs, and a eucalyptus leaf extract (ELE) enhance ceramide synthesis in the epidermis. The topical application of a skin moisturizer containing SLE66 and ELE improves the barrier functions and water holding capacity of AD skin accompanied by an improvement in skin symptoms. This is a multifaceted review that summarizes the efficacy of the topical application of a skin moisturizer containing SLE66 and ELE on atopic dermatitis.
