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.
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.
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.
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.
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.
提倡皮肤保湿以护理特应性皮炎(AD)患者的皮肤。然而,由于夏季出汗过多和湿度高,许多患者停止使用保湿剂。
研究一种含有假神经酰胺和桉树提取物的保湿凝胶在夏季增强轻度 AD 患者表皮神经酰胺合成的功效。
我们对 44 名未在夏季使用任何保湿剂的日本轻度 AD 患者进行了为期 4 周的单盲身体护理临床试验。27 名患者每天使用两次含有假神经酰胺和桉树提取物的保湿凝胶,而另外 17 名患者则不使用任何保湿剂。在第 2 周和第 4 周末之前和之后,评估每位患者的皮肤状况。
在测试期间,大气温度升高,无论是否使用保湿凝胶,皮肤干燥和脱屑均明显改善。然而,治疗组的干燥改善程度明显高于未治疗组。仅在治疗组中,红斑和瘙痒得到显著改善。仅在治疗组中,前臂皮肤水分含量显著增加。伴随着这些改善,由 Skindex-16 评估的患者生活质量也得到了显著改善。
即使在夏季,使用含有假神经酰胺和桉树提取物的保湿剂也能有效护理 AD 患者的皮肤。
