What it is
CERENOVA Oil Mouthwash is a new oral care product born from the concept of "skin care for the mouth." The mouth, like the skin, is a delicate environment covered with mucous membranes. Rather than a strong rinsing method, it prioritizes maintaining moisture and improving the oral environment. The oil, based on domestically produced rice bran oil, blends with oily stains that cannot be removed with water alone, gently enveloping and caring for the mouth. Its texture changes when mixed with saliva, and its unique formula (patent pending) spreads throughout the entire mouth even with a small amount (approximately 1-2 mL). Along with the gentle scent of rose geranium essential oil, it proposes a new oral care habit.
Ingredients
Rice bran oil, sorbitan sesquioleate, sunflower seed oil, centella asiatica extract, corn germ oil, geranium oil, polyglyceryl-5 trioleate, clove bud oil, tocopherol
How to use
Take a small amount (approximately 1-2 mL) of this product into your mouth, rinse for at least one minute, spreading it throughout your mouth, and then spit it out. The oil will change texture as it mixes with saliva, gently spreading throughout your mouth. For first-time users, we recommend starting with a small amount of about 1 mL. Once you become accustomed to it, you can use 1-2 mL as a guideline.
