I have acne treatment questions

I am an adult, and I was hoping by now I would not have to deal with acne anymore. Most people think of acne as a problem for teenagers, but I am one of those unfortunate people that get acne all through adulthood too. My mother still gets acne, so I doubt I will stop getting it anytime in the near future. How can I treat this? Many acne treatments aren’t safe if you are pregnant and nursing, so I need to find a different solution. What are the best natural acne treatments? Are these treatments safe during pregnancy and nursing? Maybe I will simply wash my face with glycerine soap and not use any treatments.
