I know a lot of people are uncomfortable with this topic but..

Ok ladies.... I am a person who gets cold sores. Yes I know it's gross, but I know there are other people out there who get them too. I don't normally get them unless I'm REALLLLY stressed out which I was about a week ago and it just now popped up on my bottom lip. I had a job interview so I just but lipstick on over it but it was still really noticeable. What do you guys do for cold sores other than abreva? I try to use abreva as often as possible but it's so dang expensive at the store. Any advice would be appreciated 🙌🏻
