SHIRO Unveils Revitalized “Rhubarb Hamanasu” Skincare: Nature’s Vitamin C Powerhouse for Radiant Skin

SHIRO’s “Rhubarb Hamanasu” Series Gets a Powerful Upgrade

SHIRO is set to unveil a revitalized “Rhubarb Hamanasu” skincare series on April 9, 2026 (Thursday). This enhanced lineup introduces new and renewed products, harnessing the natural goodness of solar-kissed Hamanasu fruit and Rhubarb to bring a vibrant glow to your skin.

The inspiration for this renewal began in 2024, stemming from a conversation with Hamanasu producer Mr. Kamide in Okopcho, Hokkaido. Due to severe summer heat and prolonged rain, the delicate Hamanasu flower petals were difficult to harvest. However, the Hamanasu fruit remained abundant. This led SHIRO to re-evaluate the potential of the fruit itself.

Upon tasting the Hamanasu fruit for the first time, the development team exclaimed, “It’s sour and delicious!” This simple, joyful discovery solidified their belief that ingredients delicious to eat are also beneficial for the skin. While the flowers offer a sweet, elegant scent, the fruit delivers a distinct tartness, brimming with nutrients.

The Power of Hamanasu Fruit and Rhubarb

Hamanasu fruit is a treasure trove of nutrients, particularly rich in Vitamin C and polyphenols. These components are known to promote clear, translucent skin2 and offer benefits for anti-aging care3. Complementing this, Rhubarb4 extract contains malic acid, which is believed to gently soften old keratin, aiding in skin renewal. By combining these two powerful ingredients, SHIRO has crafted a series that maximizes their natural efficacy.

“The natural pigments of Rhubarb4 and Hamanasu1 create a beautiful pink hue when fresh5, adding a delightful visual element to the refreshing feel,” explains a SHIRO representative. This new series embodies SHIRO’s dedication to working in harmony with nature’s cycles, utilizing available resources to evolve beloved products.

The New Lineup: Four Essential Items for Luminous Skin

Here’s a closer look at the enhanced “Rhubarb Hamanasu” collection:

Rhubarb Hamanasu Cleansing Water 150mL / 4,950 yen (tax included)

This wipe-off cleansing water not only removes makeup but also helps to gently clear away excess keratin and pore impurities, leading to refined and clear2 skin. The addition of Hamanasu fruit extract1 to Rhubarb extract4 creates a slightly thicker texture, providing long-lasting hydration after use. Its oil-free formula makes it suitable for use on bare skin, perfect for pre-makeup exfoliation. Infused with lemon essential oil6, it offers a refreshing scent with every use. Shake well before use. One bottle lasts approximately 1.5 months with 3 pumps per day.

Rhubarb Hamanasu Oil-in-Serum 30mL / 8,470 yen (tax included)

This two-layer oil serum combines extracts from Hamanasu flower7 and fruit1 with Rhubarb extract4, Marula oil8, and vibrant orange Rosehip oil9. It targets various skin concerns like dullness10 and roughness, promoting moisturized and healthy skin. Its light texture absorbs quickly, making it ideal even for first-time oil serum users. Lemon essential oil6 provides an invigorating aroma. Shake until cloudy before applying. One bottle lasts approximately 1.5 months with 3-6 drops morning and evening.

SHIRO uses Hamanasu cultivated without pesticides or chemical fertilizers by Kamide Farm in Okopcho, Hokkaido. This rose family plant’s petals and fruit are rich in Vitamin C and polyphenols. The new “Rhubarb Hamanasu” series incorporates plenty of Hamanasu fruit extract1, resulting in a fresher, more skin-friendly texture.
