New expression: make teeth black. Launching a tooth cosmetic that designs facial expressions with 'shadow' and 'accent'!

Cosmetice CCC Winter Black is a tooth cosmetic applied to the tooth surface to make teeth appear black. Unlike traditional methods focused on whitening teeth, adding the color black creates shadows and accents around the mouth, allowing for different facial expressions. Various expressions are possible depending on the application method, such as applying to a single tooth for accent, applying to all teeth for an 'ohaguro' look, applying to part of the front teeth to change their apparent shape (e.g., rabbit teeth), or drawing simple patterns or marks on teeth. This product expands the options for free expression beyond just whitening teeth. The product is priced at 16,500 JPY (tax included) for 2mL. Key features include: color makeup that makes teeth appear black, ability to change impression without grinding or damaging teeth, lasts approximately 20 hours if no food is consumed, main ingredients are food-grade, no preservatives, can be used on metal teeth and dentures, easily removed with brushing, and one bottle provides approximately 200 applications. It will be released on May 31, 2026, and sold directly and at selected contracted stores. The product is applied with a brush attached to the cap. The development background notes that while teeth have traditionally been treated as something to be whitened, there is a growing need to change the impression of the mouth as part of fashion and expression. Focusing on the contrast and shadow that the color black offers, this item was developed to enable unprecedented oral expressions.
