The three balls on the packaging of the oral products of the KIN Laboratory constitute a classification system according to the indication and the time of use of each product.
Thus, those that show a single black ball are products for daily use, for cleaning purposes, mainly with hygiene and refreshment functions.
When there are two black balls, it means that the product is intended for maintenance (for example, of the gums after an intervention at the dental clinic). Its use is indicated by the professional for a certain time.
Finally, products with three black bags are intended for intensive care and are generally recommended by professionals. Its use time is limited and less prolonged than that of maintenance products.
