About the feminak Intimate Care Series
feminak has been widely supported for its easy-to-use and cute design, achieving Rakuten ranking No. 1* for its Japanese-made menstrual cups. Through this experience, we observed a common sentiment regarding intimate zone care: "I'm interested, but I can't take the first step." Many people are hesitant, saying, "I don't know what to choose" or "I don't know how to start," which has prevented it from becoming a daily habit. In response to this background, we developed the "Intimate Care" series, proposing intimate zone care not as something special, but as a casual care routine that can be easily incorporated into daily life.

The products are designed to be easily absorbed and non-sticky, providing a comfortable feeling even when wearing underwear immediately after care, making it easy to continue as part of a daily routine.
Furthermore, by combining two types of soaps and three types of moisturizing items, each designed for a specific purpose, users can select care tailored to their skin concerns and preferred texture.
All products contain Vitamin C derivatives, Niacinamide, Dipotassium Glycyrrhizate, and Ceramide to address various skin concerns. Additionally, moisturizing items include specialized ingredients tailored to their respective purposes.
