The Foundation of Our Formulas: Hadasei-3
A proprietary complex of three ingredients, each chosen with precision, each sourced from a specific region of Japan where the conditions for growing them are perfect and nowhere else on earth quite replicates.
Akita Rice
From the cold northern prefecture where the purest water and the sharpest seasons produce a grain of extraordinary quality. Supports skin’s natural moisturizing factors for a healthy barrier.
Uji Green Tea
From the misty hills outside Kyoto where green tea has been cultivated for over eight centuries. Helps neutralize oxidative damage to reduce signs of premature aging.
Okinawa Algae
From the waters surrounding the island where the population has long been studied for its exceptional longevity. Helps moisture retention with skin-plumping polysaccharides.
Camellia Oil
Feather-light and fast-absorbing, camellia oil benefits the skin in numerous ways and is a treasured secret in Japanese skincare.
Colloidal Oatmeal
The calming variant of oatmeal has been used for centuries to relieve the painful itch and irritation common with sensitive skin.
Cranberry Extract
Full of antioxidants, collagen, and elastin, this extract supports the skin’s healthy appearance, radiance, and barrier function.
Japanese Indigo
The botanical is regarded for its deeply soothing, restorative, and calming powers, as well as supporting the skin barrier.
Peony
The blossom moisturizes, soothes, and provides superior antioxidant benefits, thanks to a natural active ingredient: paeoniflorin.
Red Algae
Red algae is packed with antioxidants and water-binding properties that deeply hydrate the skin for a healthy-looking appearance.
Japanese Rice Bran
Rice bran not only decongests pores, but can also brighten and allow better absorption of the next steps in your skincare ritual.
Sea Fennel Extract
Sea fennel extract can soothe visible irritation, minimize the appearance of fine lines and wrinkles, and boost skin’s overall appearance.
Silk
Silk is easily absorbed when infused into skincare and helps skin to look healthier, smoother, and plumper.
