Most moisturizers only hydrate. But when skin is irritated, the barrier weakens and moisture escapes. That’s why hydration alone isn’t enough.
Onsen Water Cream hydrates, repairs, and calms all at once.
Our Offense–Defense Skincare™ system makes this possible. Skin-identical ceramides strengthen the barrier. Japanese botanicals calm irritation and redness. Mineral-rich Onsen Water, known in Japan as a “natural lotion”, delivers deep hydration and increases skin moisture by up to 165%.
The result: soft, calm, balanced skin. Hydration that lasts all day.
For best results, apply Onsen Water Cream morning and night, after serums.
Targeted Correction (Offense)
Hydration that holds.
Skin Protection (Defense)
Irritated skin can’t hold onto moisture.
Calm skin is consistent skin.
Most moisturizers use water as filler. Onsen Water Cream uses water that’s been healing skin for 1,300 years.
Ushio Onsen Water from Izumo, Japan—rich in calcium, magnesium, and silica—calms inflammation, supports barrier repair, and creates the ideal environment for skin to receive hydration.
It’s not just a moisturizer. It’s the foundation that makes everything else work better.
For best results, apply Onsen Water Cream morning and night as your final step, after serums
and treatments

Apply a small amount evenly across the face and neck.

Waters from Japan’s Spiritual HeartlandUshio Onsen Water is sourced from Izumo, Shimane Prefecture—which is nicknamed “the prefecture of beautiful skin”.
For over 1,300 years, people have traveled to these waters to heal—muscles, joints, skin conditions. In Japan, doctors still prescribe onsen visits for recovery. The same waters that once healed samurai after battle now help your skin recover from the stress of everyday life.
“Bathing just once in this hot spring will clear your skin... people call it ‘the water of the gods’”—Izumo no Kuni Fudoki, 733 AD
