Clinical Evaluation of the Efficacy of Itch-Relief Moisturizers Containing Maltotetraose for Dry, Itchy, and Sensitive Skin.

Itching is a prominent clinical manifestation of sensitive skin; it reduces cutaneous barrier function, mainly caused by dryness. Scratching to relieve itching destroys the skin barrier, thus forming the itch-scratch cycle that results in additional disruption of skin barrier and chronic itching.

Persistence of the Antibacterial and Antiviral Effects after Skin Cleansing ~A New Approach to Suppress the Contact Infection~.

Handwashing represents an important personal hygiene measure for preventing infection. Herein, we report the persistence of antibacterial and antiviral effects after handwashing with fatty acid salt-based hand soap. To this end, we developed a new in vitro test method to measure persistence, utilizing coacervation formed by anionic surfactants and cationic polymers to retain highly effective soap components against each bacterium and virus on the skin.
