Aureo culture fluid and EF lactic acid bacteria, which are highly effective moisturizers, were found to be highly safe skin moisturizers with excellent durability of moisturizing effect and usability.

Aureo culture fluid is characterized by its β1,3-1,6 bonding, which has physiological activities such as anti-allergic and anti-inflammatory effects, so it is expected not only to moisturize but also to reduce allergic symptoms such as atopic dermatitis.

Aureo culture fluid and EF lactic acid bacteria were applied to the skin of women in their 20s to 50s, and the moisture content in the stratum corneum of the epidermis was measured.

In a mouse test conducted at Tokyo Denki University, the amount of hyaluronic acid as well as ceramide, which is necessary to maintain the moisturizing effect and protect the skin from external stimuli, increased.
