Human: Is there a way I can prevent a cold sore from forming? Assistant: 
Yes, there are ways to reduce the chances of getting a cold sore. One is to practice good hygiene by washing your hands regularly and avoiding touching your face. You should also avoid kissing anyone with cold sores or using lip balm that contains ingredients like petroleum jelly, which can increase your risk of developing cold sores. Additionally, you can use over-the-counter cold sore treatments such as topical creams or ointments to help reduce pain and speed up healing.
