History and Development
Uruhime Momoko was established by STEP WORLD Co., Ltd. The brand’s initial concept distinguished itself by moving away from traditional topical applications of ceramides, instead positioning them as the centerpiece of an oral beauty supplement. This approach aligns with the Japanese phrase 「美味しく飲むだけ！簡単美活！」, which translates roughly to “Delicious to take, easy beauty care.”
The name 潤姫桃子 combines characters associated with moisture (uru) and peach (momoko), reflecting the product’s signature peach flavor and broader aesthetic focus on hydration and natural beauty.
Oral Ceramide Supplement
The flagship product is a powder-type oral ceramide supplement. According to official descriptions, it is designed as a smooth, melt-in-the-mouth powder that requires no water for consumption.3 Each box contains 30 sachets, with each sachet weighing 1.5 g, for a total net weight of 45 g.
The formulation emphasizes “beauty from within,” utilizing specific ingredients sourced and manufactured in Japan:
- Glucosylceramide: Derived from 100% domestically grown Japanese rice. STEP WORLD specifies a content of 1.8 mg of glucosylceramide per serving.
- Collagen Peptides
- Vitamin C
- B Vitamins: Including Vitamin B1, B2, B6, and B12.
The brand markets this supplement for its association with the skin’s barrier function and moisture balance. It is manufactured at a GMP-certified factory in Japan.
A limited edition grape-flavored version has also been released specifically for the Japanese market.
URUHIME MOMOKO S1 Serum
Expanding into topical skincare, the brand introduced the URUHIME MOMOKO S1 Serum, a 30 mL serum manufactured in Japan. This product represents a shift from internal supplementation to external application, described by the brand as moving “from within to the surface.”2
Key Ingredients:
- Niacinamide: Present at a concentration of 10%.
- Centella asiatica (CICA)
- Peach Leaf Extract: Highlighted for its moisturizing properties.
- Tremella fuciformis polysaccharide
- Glycerin and other moisturizing agents.
The S1 Serum is formulated without fragrance, colorants, silicone, parabens, mineral oil, UV absorbers, synthetic surfactants, or animal-derived ingredients.
Manufacturing and Quality
“Made in Japan” is a central component of the Uruhime Momoko brand identity. The company highlights that both its supplements and serums are produced in Japanese facilities, with the signature glucosylceramide ingredient sourced exclusively from rice grown in Japan. This focus on provenance distinguishes the brand from competitors that may use Japan merely as a country-of-origin label without emphasizing local ingredient sourcing.
International Presence and Recognition
While originating in Japan, Uruhime Momoko has established a significant presence across Asia. The brand identifies active distribution and customer bases in Singapore, Malaysia, Taiwan, Hong Kong, and other international markets.
As of March 2025, the brand reported cumulative sales exceeding 1 million units for its series. In the retail sector, STEP WORLD has noted several awards and recognitions received by the brand in Asian markets, including:
- Guardian Singapore Awards 2023: Best Newcomer, Beauty Enhancement Skin Supplement
- Guardian Singapore Awards 2024: Best Newcomer, Beauty Enhancer Skin Supplement
- Guardian Singapore Awards 2025: Most Trendy Anti-Aging product recognition
- Watsons Taiwan Health & Beauty Awards 2023: Best Sales Award (Supplement Category)
These accolades are cited by the company as evidence of the brand’s reception in regional retail environments.
Brand Identity
Visually and conceptually, Uruhime Momoko occupies the intersection of Japanese wellness trends and accessible beauty care. Its core associations include:
- Japanese Quality: Emphasis on GMP manufacturing and domestic ingredients.
- Peach Imagery: Reflected in the name and flavor profile.
- Hydration: Focus on moisture and skin barrier support.
- Convenience: Waterless powder formats and simple daily routines.
The brand positions itself closer to the functional wellness and inner-beauty supplement category rather than traditional luxury cosmetics houses. Its trademark, registered internationally under STEPWORLD CO., LTD., protects the name 潤姫桃子 / URUHIME MOMOKO in multiple jurisdictions.2
