What it is

[Set Contents] - Sonomama Mineral Epsom Salt (actual product) 100g x 3 bags Sonomama Mineral Epsom Salt (100g) x 3 bags set! The ultimate time-saving beauty treatment while enjoying a leisurely soak in the bathtub! We discovered that a 15-20 minute soak in lukewarm water (38-41°C) containing a blend of Humicle® and Epsom Salt provides five beauty benefits not found in plain water. This is the ultimate time-saving beauty treatment that supports the beauty and vitality of busy modern people! Sonomama Mineral Epsom Salt was born from this idea. [Recommended for the following people!] - You're short on time, so you want to cut back on your bath time to get some unfinished work done! - You'd rather spend time on beauty care after bathing than taking a long bath! - You're tired! It's a hassle! You want to get out of the bath quickly and get some rest! For those of you like this, we present a "full-body beauty" treatment that can be done in as little as 15 minutes, twice a week! Only Sonomama Mineral Epsom Salt can provide this effect! Experience the benefits for yourself. <<5 Time-Saving Beauty Treatments>> (1) You can simultaneously perform body, facial, and hair & scalp care while soaking in the bathtub, achieving "Three in One, Full-Body Beauty Care"! (※1) (2) Good sweat = "light sweat"! (※1) "Light sweat" is a natural beauty serum. Keeps your skin moisturized even after bathing! (3) The soft water envelops your skin like a veil, improving skin texture and moisture! (*1) (4) Gently warms your body to the core, keeping you feeling warm even after bathing! (*1) (5) Supports the production of heat shock proteins (HSPs), which protect us from internal and external stress! (*1) (*2) Body Care: Dissolve 50-100g of this product in 200L of water (38-41°C) and soak for 15-20 minutes. The "double effect" warms your body to the core, keeping your entire body warm and moisturized even after bathing! (*1) Facial Care: Soak cotton or a face mask sheet in lukewarm water with this product dissolved in it. Lightly squeeze out the water and leave it on for 5-10 minutes. (*3) It removes fine impurities from the skin's surface, leaving it soft and maintaining excellent moisture retention. (※4) Hair & Scalp Care: Dissolve this product in hot water and pour it over your head, then massage it into your hair and scalp. (※5) The chelating properties of fulvic acid remove scalp impurities and replenish minerals in your hair for smooth, silky hair. (※4) <<Featured Ingredients>> Rare Ingredient "Humicle(R)" Fulvic Acid Mineral "Humicle(R)" is fulvic acid (a natural plant organic acid) extracted from humic shale, an ancient plant deposit dating back approximately 100 million years, using only water. Not all fulvic acid is the same; its properties vary depending on the source. Humicle(R) is a rare ingredient, with only 1.2% of the product being harvested, and contains a balanced blend of over 50 naturally occurring minerals, ensuring efficient absorption. This patented ingredient, supported by extensive evidence from collaborative university research, is the first fulvic acid ingredient in Japan to receive COSMOS certification (*6) from the French company Ecocert. Its benefits extend beyond inner care to include full-body beauty care for skin, hair, and nails. High-Purity Epsom Salt: Epsom salt is a crystal of magnesium sulfate (MgSO4), a natural mineral found in abundance in seawater. While it's called "salt," it contains no salt. Its name, "Epsom Salt," is said to have originated in the late 15th century, when it was discovered in the town of Epsom in southern England, hence the nickname "Epsom Salt." In recent years, its excellent beauty and health benefits have garnered attention. This product uses carefully selected, over 99% pure Epsom salt. It quickly dissolves in hot water, enveloping the skin like a veil, providing a powerful warming effect that gently warms the body to the core. *1: Effect of bathing. Results may vary from person to person. *2: What are heat shock proteins (HSPs)? Their expression level increases in response to stress, such as heat, protecting cells from stress. They also function to repair not only psychological stress but also external damage. Soaking in lukewarm water for 15 to 20 minutes promotes HSP production. This is known as the "HSP bathing method." HSP levels increase, peaking two days after bathing. This method is recommended for maintaining relatively high HSP levels, especially if you practice this method twice a week. *3: Please refrain from bathing if you have skin abnormalities such as redness or cuts. *4: Experiences vary from person to person, and we cannot guarantee effectiveness. *5: Use water that is not too hot. When pouring hot water onto the scalp, be careful not to get it in your eyes. *6: COSMOS stands for Cosmetic Organic and Natural Standard, an international system that certifies the quality of organic and natural cosmetics.

How to use

Add 50-100g of Sonomama Mineral Epsom Salt to water between 38-41°C and soak for 15-20 minutes. Discontinue use if your skin does not respond to the product, i.e., if any of the following occurs. Continuing use may worsen symptoms, so we recommend consulting a dermatologist. (1) If you experience any redness, swelling, itching, or irritation during use. (2) If the above symptoms occur after direct sunlight exposure to the applied skin. If the product gets into your eyes, rinse immediately. Store in a dark place at room temperature. Avoid storing in damp or humid places such as bathrooms. Keep out of reach of children. Do not eat this product. Some bath heaters, such as 24-hour baths, cannot be used with certain machines. Please refer to the instructions for your model. *Magnesium sulfate (Epsom salt) may contain colored particles or form clumps during the manufacturing process, but this does not affect the quality.
