Objectives: This study aimed to evaluate the effects of a magnesium chloride-containing moisturizer on skin health indicators and subjective symptoms in older adults with dry and itchy skin. Methods: A single-blind intervention study was conducted with 34 nursing home residents aged 65 and older in Daegu. The experimental cream was applied to the right calf and the control cream to the left calf twice daily for four weeks. Skin pH, hydration, transepidermal water loss (TEWL), pruritus, and subjective skin symptoms were assessed at baseline, two weeks, and four weeks. Results: The experimental site showed significantly lower skin pH compared to the control site (p<.001), with trends of increased hydration and decreased TEWL. Repeated-measures analysis showed significant changes over time, but no interaction effect between time and group. Subjective symptoms such as moisture, scaling, roughness, itching, and scarring showed greater improvement in the experimental site compared to the control site. Conclusions: This study confirmed the positive subjective responses, maintenance of acidic skin pH, and potential alleviation of symptoms with a magnesium chloride-containing moisturizer, suggesting its viability as an adjunct ingredient to ceramide-based formulations.
