Why the “Few-Minute Bath Care” Became a Sensation
The ‘Secret Paste’ resonated deeply with its target audience by transforming the daily bath into a precious self-care ritual. In a society where women often find their personal beauty routines pushed aside by the demands of work and family, this product offers a refreshing alternative.

Feedback poured in, highlighting the product’s seamless integration into hectic lifestyles. Users have shared glowing remarks, with one remarking, “It’s so easy to keep up with, even on hectic days, because I can just use it during my bath. I don’t need to carve out special time; it just fits into my daily routine!” This sentiment echoes a growing trend in Japan for “time-saving beauty” and at-home carbonated skincare, as evidenced by rising search queries like “quick beauty tips” and “busy mom skincare.”

A Brand Born from Real-Life Challenges
PRINCIPAL’s development was driven by a commitment to address the reality of modern women who, despite their desire for beauty, often sacrifice their personal care time. The brand’s powerful message, “I am the protagonist again,” speaks directly to this struggle, encouraging women to reclaim moments for themselves. The ‘Secret Paste’ was conceived not as another chore, but as an opportunity to rediscover oneself within the practical timeframe of everyday life—specifically, during those few minutes in the bath.

Unveiling the “Secret Paste” Features
The ‘Secret Paste’ is meticulously designed with three core principles to ensure consistent use and effective results:
-
Unique Carbon Dioxide Generating Formula: This innovative formula reacts with moisture on the skin’s surface, releasing carbon dioxide. It aims to hydrate the stratum corneum, helping to prevent dullness caused by dryness and promote a brighter complexion.
-
Encapsulated Beauty Ingredients: The paste incorporates encapsulated beauty ingredients, engineered to deeply penetrate the stratum corneum. This design helps maintain healthy skin by delivering beneficial components effectively.
-
Simple Bath-Time Ritual: The product offers a straightforward application: after washing the face, apply an appropriate amount during a bath, leave for a few minutes, and then rinse. This design ensures it integrates effortlessly into existing daily routines without requiring extra time or effort.
