What must be done to pencil cosmetics before each use?

Pencil cosmetics must be sharpened before each use to ensure they apply smoothly and effectively. Sharpening helps to create a fine point that allows for precise application, which is especially important for products like eyeliners and lip liners. Additionally, the action of sharpening removes any outer layer that may have been contaminated during previous applications, thus promoting hygiene and reducing the risk of bacterial growth. This practice aligns with industry standards for maintaining cleanliness and safety in cosmetic application.

While other options, like wiping with alcohol, could also be important for maintaining hygiene, sharpening specifically addresses both the functionality of the product and the cleanliness by removing any potential contaminants. Storing in a refrigerator is not a common practice for pencil cosmetics and tossing out the product would not be practical or necessary with proper maintenance.
