Although there does seem to be some connection between a person’s blood lines (genetics) and whether they are or are not prone to getting acne, there are no clear cut definitive answers as to whether acne is definitely a genetic trait or not, because there hasn’t been a specific gene difference discovered yet for this. I can tell you that for me personally, my mother never had acne really and my sister did not either. My dad said he used to get acne when he was in his teens, but none of them had it as severe as I did when I was in my teens and even into my early adulthood. So for me, I was trying to figure out what the genetic connection was, if any, and it was pretty clear to me where my genetic connection came in. It was definitely on my mom’s side, with my mom’s sister (my aunt), and her daughter (my cousin) had acne pretty bad too. I traced it to them because my cousing and I also had the exact same birth mark on our legs, a dime sized dark spot which she had gotten removed years and years ago for safety reasons and whih I also finally broke down and got removed just two years ago from my leg for the same reasons. We both had acne that was so bad at times it becamse cystic and painful. She actually went on Accutane when she was younger, and it did help her skin immensely, but now that she is older she does think that it has also dried her out as well, because it does basically cease your oil production, which is the whole point of the medication. This was the only genetic link for me though. Some of you that have acne may have a parent that has acne as well, and for you that would be where you can trace it back to, but there are also those anomalys who have acne when absolutely no one in their family suffered from acne. It really is hard to tell, but it definitely has something to do with the individual’s hormone balance, which can definitely be a trait that is inherited or not inherited.
