Moisturizers(Cosmetic Ingredients)

Moisturizers are formulated to supplement the stratum corneum’s ability to retain moisture and to prevent a decrease in its water content. The stratum corneum is the outermost layer of the skin, and maintaining an appropriate level of hydration helps preserve the skin’s barrier function and flexibility.

However, factors such as the environment and aging can impair its moisturizing capability. Therefore, cosmetics commonly contain ingredients that help retain moisture in the stratum corneum or substitute its natural moisture-retention function.
