Strange problem with skin

Hi all,
I have a question about problem which is very significant for me.
I'm young man. I have a strange kind of acne. Strange because I've tried many methods to clear my skin with no result.
I want find the way to make my skin clear and health.
Is that problem essential for you?
What kind of medical preparation do you use? And what about effectiveness?
Can you suggest me treatment which will be efficient for my skin?
I'm really need your practice for it!

Thank you,
David.
