What does skin biopsy reveal in lab tests?

Hi MeFi, I've asked about skin issues before sometime last year and I still haven't found what it could be. My dermatologist said that I have become immune/resistant to topical treatments (benzyl perox, clindamycin, clindamycin, erythromycin) and that he needed to take a sample and conduct a skin biopsy. On a first whim, he said I likely have 'Folliculitis' but he's not sure since my skin didn't respond to topical treatments. So today he did a skin sample and I'm just curious to what exactly do lab-results show when it comes to skin biopsy. Do they look for certain bacteria or do they get an overall result of what has been in my body as far as food, drugs, liquids go? All I really use 'recreationally' is marijuana through a vaporizer to treat my neck pain but this dermatologist is sorta ultra-conservative and a friend of the family so I'd hate have to explain stupid things to him should they even come up during the test results. TL;dr - Do Skin Biopsy lab results show drug use or just skin bacteria? Thanks everyone!
