The fact that she keeps mentioning it in her video and blog suggest that she was wearing it and loving it before. I don’t think is one time.Lily claims her lip issue came from the cheap lipstick she used (or that was used on her by Sam) on her wedding day. So you're right I just think a lot of us don't believe that the one-time use of one cheap lipstick caused a problem for 3 (?) years. Whatever reaction she had to the product could have been reduced if she had given her lips a break instead of applying even more lipsticks (pr experiences) and lip balms later on.
