No homo, but you're looking very buff in that pic. You're nipple looks sort of weird though. I think it's because your pec is so big it's made your nipple un-circular. Is that why?
I wasn't recommending accutane, I was recommending retin-a, a topical medication. A topical medication that isn't designed to be absorbed into the blood stream will almost always be safer than a medication which is absorbed into the bloodstream (antibiotics). If you have acne on you shoulders and your face, and you only use retin-a on your face, you'll still have acne on your shoulders.
Any use of antibiotics can contribute to antibiotic resistance. In fact, low doses of antibiotics can be worse than high doses, because high doses will kill all bacteria, whereas low doses will allow the bacteria with some antibiotic resistance to survive. Antibiotic resistance is a serious problem, there's already doomsday mrsa. You're right, most antibiotics aren't dangerous to use for most people, but they do cause liver strain. If you drink on antibiotics, that can cause liver damamge.
If you use antibiotics to reduce inflamtion and not kill bacteria, why not just use cortisone? Cortisone will be much more effective at reducing inflamtion, and is safer if it's used topically. Antibiotics are used to kill bacteria.
I think you thought I was recommending accutane because my post wasn't clear. Retin-a is less dangerous than antibiotics which are much less dangerous than accutane. Accutane is a very effective treatment, though. It tends to get vilified needlessly.
