Applicators are devices designed to apply substances, such as creams, gels, or medications, directly to a specific area of the body. They come in various forms, including syringes, rollers, and brushes, each tailored for different applications. Applicators help ensure precise dosage and even distribution, making them essential in fields like pharmaceuticals and cosmetics. These devices can enhance user experience by simplifying the application process and improving hygiene. For instance, single-use applicators reduce the risk of contamination, while reusable ones may offer ergonomic designs for better grip. Overall, applicators play a crucial role in effective and safe substance application.
