I have a major acne problem, what should I do?

I have a major acne problem which cannot be corrected. Acne all over my face. Went to several doctors but no solution can be found. Was tested for just about everything. CBC, TSH, HB, Blood sugar and kidney. All normal. Also tried all kind of acne products including clindamycin and minocycline. Nothing. What should I do?
