Lichen planus is difficult, I've had it for 7 years now. Hate it. But recently I've been using pure virgin coconut oil on my skin have not had an out break yet and always have it in Dec. near christmas time and in July. I've been using it for about 3-4 months. If one appears it just dries up in a day or so, haven't had a huge break out to know what the reaction would be. My suggestion try extra virgin coconut oil.
