地域在住高齢者の皮膚乾燥に対する保湿方法の違いによる保湿効果の検討

抄録

[Purpose] To examine the moisturizing effects of applying and spraying a moisturizer composed of a mixture of urea, glycerin, and purified water on dry skin in community-dwelling older adults.

[Methods] This before-after comparative design in quasi-experimental study included 8 adults aged 60 years and older. The stratum corneum hydration was measured using Mobile Moisture HP10-N®. First, both lower legs were allowed to acclimate to the environment for 15 min, after which the stratum corneum hydration was measured. Second, moisturizer was applied to one leg and sprayed on the other leg. Stratum corneum hydration was measured immediately after moisturizer use and 5, 15, 30, and 60 min after use.

[Results] Regarding moisturizing habit, it was found that 7 participants did not habitually moisturize. Skin dryness of the lower legs was observed in 6 participants. No differences were observed between the two methods in terms of the degree or duration of the moisturizing effect. Stratum corneum hydration significantly increased immediately after application and significantly decreased after 5 min for both methods.

[Conclusions] There was no difference in the moisturizing effects between applying and spraying. However, spraying is a simple procedure, it may lead to the development of a moisturizing habit.
