I've been researching skin bacteria a lot lately, and i'm really confused. Everything is saying that skin bacteria are actually really important for our skin function, not gut flora so much, eventhough it is. However, I dont understand where they come from and what happens when people use antibiotics or antibiotic soaps and such...it's not like these bacteria are wiped out, eventhough they should be when we use such products? What happens to them? Do they go dormant? I feel like you could take antibiotics for a year, but the skin bacteria, such as p acnes or armpit bacteria would come back? If they only live on human skin, where the hell are they coming from? If you wash them away, how do they come back, and do they ever? I'm starting to be worried about if I can have healthy skin without surface bacteria?

Get into an intimate relationship with someone. That should replenish much of your microbiome.

The bacteria come from the environment in which you live. If you use antibacterial soaps to kill them, then you must wait for them to recolonize on your skin.
"I feel like you could take antibiotics for a year..." Not unless you have an chronic or stubborn immunological disease. Otherwise, you're carpet-bombing all the symbiotic bacteria in your body, and your immune system will be seriously impaired.
"I'm starting to be worried about if I can have healthy skin without surface bacteria?" Stop worrying. Human evolved to co-exist intimately with some bacteria and defend against others. In fact, washing or showering too often to get rid of surface bacteria removes the top layers of skin oils that protect against pathogenic bacteria from getting into your body.

Maybe it is simply from interaction with other carriers [people]? Which is pretty much unavoidable.
With something like acne you can improve it, or get rid of it even, by constantly "killing" the p-acnes but poor old p-acnes isn't actually the real root of the problem, it's our bodies over reaction to the poor guys. No doubt there is probably some side effect to getting rid of the the p-acnes and whatever else lives on our skin, but as with most of medicine, the benefits are considered to out way the side effects.
The human microbiome is a very interesting area and still so misunderstood. After all, they say the average adult human posses 10 times the number of microbial cells than human cells. Which is a lot.
Like everything in life there has to be a balance between everything or you start getting trouble. Just how much disease in the World is connected to the critters that are part of us all?
