No, when I first stopped biting and left my lip alone it would 'scab up vey quickly - thick in a matter of days and would be a yellow/green colour and would be so thick that it would 'indent' into my lip, like a creator!. I haven't been biting my lips for about 3 years and only been doing this current leaving only route for about 6 months, what I do is leave the scab to develop until I really need to look normal, like going out with mates. Try and peel the scab off as delicatley as possible. To start with this was really hard. Now what is happening is that the peeling is not so violent ie the ' the scab doesn't develop as fast so I believe it is gradually slowing down the immune response that must have been happening.It's much much better than when I first started, when the scab gets bigger it stays a clearer colour too, so you would only notice when you touch it. Basically all the peeling/scab on the affected area IS the skin of the lip so you have got to leave it alone, it's basically exfoliating at a very fast rate and until there are tablets or something the only way to stop it is not touch it - in my opinion!. I know this is virtually impossible but I can't see any other way. I have even ended up timing the process, if I know i've got a big weekend on i'll time it so I can ease the scab off for that day. Also I now take of virtually the whole scab underneath which reveals nearly normal looking lip, it just looks a bit delicate - NOT raw and the process of the buuld up of skin starts again until it stops hopefully!
O, I never get my lips wet by the way, when they turn to mush you might aswell be peeling them off. I went through a stage of sucking them off in the shower but this takes the lip skin right back to it's rawness like you just bitten them off.Also I quit drinking and smoking, this made no difference and I've done the diet thing also no difference, only thing that has made any difference is leaving them alone.
Hope that has given you some insight.
