Japan Revises the Sun Protection Test Methods

In Japan, the determination of the UVA-prevention efficacy of cosmetics can refer to "ISO 24442: 2011 Cosmetics - Sun protection test methods - In vivo determination of sunscreen UVA protection", which was first published by the International Organization for Standardization (ISO) and adopted by the Japan Cosmetic Industry Association (JCIA) as a voluntary standard for sunscreen cosmetics.
