I am having worst condition of acne, on my chin I have nodules that never matures, nor form a proper pimple or acne? Any recommendations?

Acne. The best treatment for your type of acne is oral antibiotics like solodyn (minocycline) or monodox. If antibiotics are not helpful, there is also accutane. 80% of patients who take Accutane never have acne again.
