Hey, I am a young male that recently turned 20, my question is about facial hair, my facial hair seems to be growing slowly and I am just worried that, like a few people I know will only grow in certain patches and stop there, how old until my beard is fully grown, will acne prevent hair from growing on that spot, does acne cream stop hair growth because of the chemicals in it, do acne scars without a doubt mean a bald spot for my beard in that scar area. At what age should I expect full growth, also, I think I have noticed my beard growing sligthly quicker when I exercice, this beeing from the raise in testosterone I assume right? I know my questions are a little all over the place, I would really appreciate an asnwer to all of them
