I was suffering from these Ozzing crusts on my face for about 4 years. I tried all sorts of treatments and diets but nothing worked. Then I was prescribed deolate (terbinafine) by my doctor for an unrelated issue. This seems to have cleared them up completely. I haven’t had a single crust for 8 months and counting, the longest I have gone with out one before deolate was probably 2 weeks.
Hope this helps, cheers
