My son had the same problem . Then we went to dermatologist . He appointed treatment. Half-year with medications - tablets . Each month, he donated blood for analysis. But it finished, now his face is clean . It was in Israel .

That irritates me and my face too. So now i'm using Sealling Jell which can vanishes acnes slowly.

But I used to take the medicines few years ago. I think it depends on several causes, like going to bed very late, dirts and smokes, foods etc. The most importanting this is to keep our faces clean, always!
