Detailed answer

To prevent lip balm contamination, it is important to cleanse your lips before applying. This helps remove any buildup of bacteria or dirt that may be present on the lips. Additionally, avoid sharing your lip balm with others to prevent the spread of germs. Each person's mouth contains its unique microorganisms, which can transfer to the lip balm and increase the risk of contamination. It is also crucial to keep the lip balm tube clean by wiping off any visible residue or dirt. Regularly inspect the product for signs of contamination, such as changes in texture, odor, or color. If any of these signs are present, it is advisable to replace the lip balm to avoid potential infections or irritations.
