Evaluation of the Relationship between Optimum Application Time for Moisturizers after Bathing and Their Effects on Humans

Abstract

To evaluate the hydration effect of combination bathing and moisturizing regimens, we applied moisturizers after bathing every day and quantified cutaneous hydration status for 2 weeks in eight healthy volunteers. Hirudoid (Heparinoid)^® soft, Vaseline, and Pastaron (Urea)^® soft were applied at 2 mg/cm² to their forearms 1 minute and 1 hour after bathing for 2 weeks. We measured the cutaneous hydration before and after the study almost every other day. There were no significant differences between the application of each moisturizer at 1 minute and 1 hour after bathing. These moisturizers provide hydration benefits by continuoususe. In conclusion, to be effective, patients should apply moisturizers every day at any time they prefer.
