Does Rosacea and Acne have an effect on the growth of facial hair?

I'm a healthy 29 year old man but I have almost no facial hair. I have a little on my chin and a little stubble on my upper lip but thats it. I had bad acne during my teens and eventually got on accutane. I have rosacea as well. Every guy on my dad's side can and my moms dad could. Whats the deal? Did all those years of acne medication mess something up?
