What natural ingredient did Japanese women use as a toner?

Japanese women traditionally used a rice and water mixture as a toner due to its beneficial properties for the skin. The starch in rice water contains vitamins and minerals that can help improve skin texture, brighten complexion, and provide hydration. This practice has been part of Japanese beauty rituals for centuries, reflecting a deep understanding of natural ingredients and their effects on skin health.

Using rice water as a toner can enhance the skin's elasticity and promote a smoother appearance, making it a popular choice among women seeking to maintain youthful and radiant skin. Additionally, the gentle nature of rice water makes it suitable for various skin types, contributing to its long-lasting use in Japanese skincare routines.
