Infused with fermented camellia flowers from Japan’s Goto Islands, Shiseido’s new Ultimune Power Infusing Serum is more than a pretty bottle—it’s a powerhouse of hydration, resilience, and glow. Here’s how this serum made me a believer in floral-based skin care and why it’s earned a permanent spot on my vanity.
A flower with a secret
Tucked along Japan’s western coast, the Goto Islands are known for their serene blue waters, lush green hills, and one striking bloom: the camellia. With petal patterns resembling nature’s own mandala, camellias have long been prized for their beauty. But thanks to Shiseido, these flowers are now taking center stage in skin care.
Camellias on the Goto Islands have had to toughen up—weather in the region can shift rapidly, with strong winds and harsh conditions. This resilience is exactly what makes the flower so potent as a skin care ingredient. Building on centuries of Japanese fermentation expertise—think sake and miso—Shiseido has taken camellia extract and fermented it to enhance its skin-healing properties. “Through the fermentation, we are able to increase the amino acid volume to 3.4 times higher,” a brand rep shared. That’s good news for your skin: amino acids help boost collagen, improve hydration, and support the skin’s natural barrier.
From root to petal: every part matters
The Ultimune Power Infusing Serum doesn’t stop at fermented camellia—it goes deep, using every part of the plant. The petals, seeds, leaves, and stems all serve a unique purpose. Camellia seed oil and extract deeply moisturize and help promote collagen production. The leaves and flowers, meanwhile, work to calm inflammation and soothe sensitive skin.
But the serum’s formula is even more complex than a single flower. Other natural actives, like reishi mushroom and iris root, come together to fortify the skin barrier. These ingredients are known for their adaptogenic and antioxidant properties, meaning they help skin resist stress and environmental damage. In essence, it’s not just a product—it’s a floral shield for your face.
This multilayered approach to formulation is deeply rooted in Japanese skin care philosophy, where layering, nourishment, and prevention take precedence over quick fixes. The serum reflects that sensibility. It’s not flashy in how it works—it simply makes your skin feel… better.
A red bottle with real staying power
Admittedly, I was initially drawn to the serum by its packaging. The red bottle is striking and elegant—a perfect pop of color on my countertop. But beauty packaging can only go so far. What surprised me most was how quickly this serum became a part of my daily rhythm.
The texture is lightweight and almost water-like, absorbing instantly without any sticky residue. It layers beautifully under moisturizers, sunscreen, and even makeup—no pilling, no fuss. After using it every morning and night for three months, I noticed that my skin felt consistently more hydrated, plump, and, dare I say, luminous. The fine lines on my forehead seemed softer, and my usual dryness during seasonal transitions was a non-issue.
I’m someone who tests dozens of skin care products each year, and I rarely finish a bottle of anything. But this serum? I used it down to the last pump. That in itself is rare—and telling. Even more surprising: I’m already planning to crack open another bottle. In a world of endless new launches, this one has earned its place in my long-term rotation.
A floral ritual worth repeating
More than a product, Shiseido’s Ultimune Power Infusing Serum has become a moment of calm in my daily routine. There’s something grounding about applying a formula made from a resilient, windswept flower—fermented and fine-tuned by centuries of Japanese wisdom. Each drop is a quiet reminder that beauty can be both delicate and strong.
Whether it’s the result of camellia’s natural potency or the thoughtful formulation behind it, this serum has transformed how my skin looks—and how I feel. It’s proof that sometimes, the simplest rituals rooted in nature can deliver the most powerful results.
