Why It Works
Mineral Clay Foam is crafted using Japan’s advanced two-step blending method. By mixing the ingredients in two stages, this process creates a dense, elastic foam even with a small amount. This high-quality foam is easy for anyone to achieve and helps deliver a refreshing cleanse while leaving the skin comfortably hydrated after each wash. Formulated with “marine silt,” a mineral-rich ingredient known for its ability to adsorb impurities and support the skin’s moisture retention. This natural marine silt is formed over many years on the ocean floor in Japan. Because it is gentle on the skin and minimizes irritation, it is thoughtfully suited for even delicate or sensitive skin.

*Based on a clinical trial conducted on 10 participants to evaluate the efficacy of Mineral Clay Foam and Clear Gel Cleanse immediately after use and over a 12-week period.
Japanese Clay
In Japan, natural clay has long been valued for its skincare benefits. Mineral Clay Foam is formulated with this time-honored ingredient. Nurtured over millions of years on the ocean floor, Japanese clay is rich in minerals that help gently draw out impurities while maintaining the skin’s moisture, leaving it soft and hydrated.
Hibiscus Leaf Extract
Traditionally valued in Japan for its skincare benefits, hibiscus leaf extract is often referred to as a plant-based alternative to hyaluronic acid. Known for its excellent moisturizing properties and antioxidant benefits, it also helps minimize the effects of UV exposure, supporting healthy, well-balanced skin.
Sodium Hyaluronate
A highly moisturizing ingredient commonly used in high-quality Japanese skincare. It not only delivers hydration to the skin but also helps maintain moisture within the stratum corneum, keeping skin hydrated and protecting it from dryness.

Step 1: Wet the Foaming Net
Wet the foaming net with water, then gently squeeze out the excess. (Too much water will make it difficult to create a rich lather, while too little water may prevent it from foaming well, so adjust as needed.)
Step 2: Apply the Cleanser
Dispense about 1 cm of the cleanser onto the foaming net.
Step 3: Create a Lather
Hold both ends of the foaming net and rub them together, swirling about 30 times to create a rich, bouncy lather.
Step 4: Squeeze Out the Foam
Once a fine, dense lather forms, gently squeeze the foam out from the net. Aim for about the size of an apple, and it’s ready when it stays in place even if you turn your hand upside down.
Step 5: Start Cleansing
Apply the foam to your T-zone, cheeks, and chin, then gently spread it across your face. Cleanse in soft, circular motions without letting your fingers touch the skin directly. Be sure to cleanse carefully along the hairline as well.
STEP 6: Rinse
Once you’ve gently worked the foam over your entire face, rinse thoroughly. It helps to lightly remove the foam from the surface first, then rinse it away. Use lukewarm water (around 30–32°C / 86–90°F) and rinse as if you’re gently cradling your skin. Aim to rinse about 30 times with running water. Taking the time to rinse properly helps support clear, healthy-looking skin. Be sure to rinse carefully along the hairline and jawline, as these areas are easy to miss and can lead to skin concerns if any residue is left behind.
Step 7: Pat Dry
After cleansing, gently press a clean towel against your skin to absorb excess water. Avoid rubbing, as it can irritate and damage the skin. Lightly patting is all you need.

Our Approach to Cleansing
In Japan, cleansing has been valued for over 200 years, dating back to the Edo period. For example, komenuka (rice bran) was traditionally used by Kyoto’s maiko and kabuki actors as a cleansing ingredient, and its benefits are still recognized in modern skincare science today. In this way, cleansing has long been valued and carefully studied in Japan. When cleansing is not done properly, impurities left on the skin can make it more difficult for lotions, serums, and creams to absorb, reducing the overall benefits of your skincare routine. With this in mind, we focus on cleansing and aim to create formulas that help maximize the benefits of your skincare.
Gentle on the Skin
Cleansing power is one of the most important functions in any face wash. Even if an ingredient is effective, we avoid using it if it may be harsh on the skin. Mineral Clay Foam is designed with a focus on gentleness, using only carefully selected, low-irritation ingredients such as coconut-derived amino acids and sea silt. The formula is designed to be suitable even for babies and those with sensitive skin.
