How can I prevent a cold sore?
assistant
To prevent a cold sore, you should practice good hygiene such as washing your hands regularly and avoiding touching your face. Avoid kissing or sharing items like lip gloss, toothbrushes, or eating utensils with people who have the virus. If you do get a cold sore, avoid touching it and try using an over-the-counter cold sore cream to help reduce pain and speed up healing.
