I purchased this as a gift but didn't use it, so I'm offering it to someone who might be looking for it. Excerpt below: This mouthwash is great for oral care and personal hygiene. While you expect results, you might also be concerned about the ingredients since you put it in your mouth. "THE MOUTHWASH" was created through a collaborative project between THE and Mash Beauty Lab Co., Ltd., which operates Cosme Kitchen, a select shop for natural and organic cosmetics from around the world. The ingredients are 99% naturally derived*. Moisturizing ingredients made from soap nuts and calendula provide moisture in the mouth, and fragrances using menthol derived from peppermint and essential oils of spearmint provide a natural refreshing sensation. It's alcohol-free, so it doesn't sting when you put it in your mouth, and it can be used safely by children. There are two types of mouthwash: "oral rinse," which is used for oral cleansing and as a finishing touch after brushing your teeth, and "liquid toothpaste," which is used when brushing your teeth, like toothpaste. "THE MOUTHWASH" is a liquid toothpaste, so it is most effective when used before brushing your teeth. By putting 5-10mL in your mouth and rinsing for about 20 seconds before brushing, you can brush your teeth with the dirt and debris loosened, so you don't have to use excessive force. Also, since it doesn't contain abrasives, unlike paste-type toothpaste, you can brush your teeth without damaging the tooth surface. After removing the dirt and rinsing your mouth with water, the remaining mouthwash ingredients adhere to the teeth and prevent dryness, also reducing plaque buildup. It is also recommended to use it with THE TOOTHBRUSH by MISOKA, a toothbrush that makes your teeth smooth just by brushing with water. If you put "THE MOUTHWASH" in a cup and soak the bristles in the liquid before brushing, the effect of the toothbrush's nano-mineral coating will give you smooth teeth like a glass surface, and the mouthwash will condition the oral environment, preventing bad breath and cavities, and maintaining healthy white teeth. This is a combination that can be called THE oral care.
