BACKGROUND
Skin moisturizing is advocated to take care of the skin of patients with atopic dermatitis (AD). However, many patients stop using moisturizers in the summer because of excessive sweating and high humidity.
OBJECTIVE
To examine the efficacy of a moisturizing gel containing a pseudo-ceramide and a eucalyptus extract, which enhances epidermal ceramide synthesis of patients with mild AD in the summer.
METHODS
We performed a single-blinded 4-week clinical trial of body care on 44 Japanese subjects who had mild AD. They had not applied any moisturizer on their body in the summer. Twenty-seven subjects used the moisturizing gel containing a pseudo-ceramide and a eucalyptus extract twice a day and the 17 other subjects did not use any moisturizer. Prior to and at the end of weeks 2 and 4, the skin conditions of each subject were evaluated.
RESULTS
During the test period, the atmospheric temperature increased and skin dryness and scaling significantly improved with or without application of the moisturizing gel. However, the improvement in dryness of the treated group was significantly higher than that of the nontreated group. Erythema and itchiness were significantly improved only in the treated group. The skin hydration on the forearm increased significantly only in the treated group. Accompanying those improvements, the quality of life of the subjects, evaluated by Skindex-16® , was significantly improved.
CONCLUSIONS
The usage of a moisturizer containing a pseudo-ceramide and a eucalyptus extract is effective for care of the skin of AD subjects even in the summer.
