I have had a VL for almost 24 years on my lower lip. It has been examined by several consultants and recommendations have been for deep laser treatment as it is very large and goes quite deep.
I've already had cryosurgery on it in the past and that made it twice as big, a big white inner scarring next to it and now it is like a ball rather than flat. I've never tried the castor oil but I'm going to give it a go!! At the same time I'm going to try it on my xanthelasma too! There is no risk of cancer btw
