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.
Skin-identical ceramides strengthen the skin 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.
10% Glycerin—draws and retains moisture for long-lasting hydration.
Mugwort Extract + Dipotassium Glycyrrhizate: soothes everyday sensitivity.
Ceramide Care Technology—ceramides (NP, AP, EOP) that mimic skin’s natural structure to strengthen the barrier.
Ushio Onsen Water—19 essential minerals that hydrate, calm, and help skin absorb treatments better.
Bio-Squalane—lightweight, breathable.
Dokudami Extract + Phytosphingosine—helps sensitive skin stay stable.
Shikuwasa + Acerola Fruit Extract—antioxidant support against UV and pollution.

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 creates the right environment for actives to penetrate effectively.
For best results, apply Onsen Water Cream morning and night as your final step, after serums and treatments
Apply
Apply a small amount evenly across the face and neck.
For enhanced results, pair with De-Spot or C³ Glow Veil.
Ushio 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

Powerful actives that visibly improve skin concerns.
Soothing ingredients that strengthen and protect.
Each DEAU formula includes Japanese botanical extracts, carefully curated to reflect a formulation mindset rooted in balance, restraint, and respect for skin—principles central to Japanese skincare.

Most notice improved hydration and comfort within the first week of consistent use.
I have redness and sensitivity across my cheeks that nothing has consistently improved. 3 weeks into using this and my skin started looking calmer throughout the day. Not completely gone but noticeably less reactive. Something in this is doing more than other moisturizers have.
My toddler caught me across the cheek and every product I tried to put on it stung. Put this on expecting the same. It just felt calm. Completely gentle. The scratch cleared up faster than I expected. My go-to now when my skin needs something calm.
Cleanser, this, SPF. That's it. My skin has been more hydrated and clearer than it was with a 10 step routine. Sometimes the answer really is less.
My skin gets really dry in winter and I always have to switch to something heavier. This year I just used more of this and never switched. Skin stayed comfortable and hydrated through the whole winter. That's never happened before.
I have oily skin and most moisturizers are too heavy or leave a film by noon. This one absorbs completely in under a minute. My skin stays hydrated all day without adding any extra shine. No breakouts in 2 months. First moisturizer I've actually stuck with.
I wear makeup every day and my moisturizer has to perform under foundation. This absorbs in about 45 seconds and my foundation sits perfectly on top. Zero pilling or sliding. My skin has also been more hydrated overall for 2 months. Two wins in one product.
I ran out for 4 days while waiting for my reorder. Those 4 days told me more than weeks of using it did. Skin was tighter, duller, more reactive. Back on it and back to normal within 2 days. That's how I know it's actually doing something.
Living in Florida means most moisturizers add to the stickiness I'm already fighting. This one absorbs completely even in the heat and humidity. My skin stays hydrated without feeling like my face is wrapped in something. First one that's worked here.
