@Patty111,
Hiya,
Well, obviously this is a question you can ask your doctor, and maybe get a referral to a dermatologist for the specifics. I'd also ask either/both about scar revision if it bugs you.
I can tell you, though, that I am 51 years old and I still get acne. For me it is a stress-related thing. So, anecdotally at least, I'd say it's possible for you to continue getting it.
Some people swear by Arnica for scars but it didn't seem to do anything for me re scars on my abdomen from surgery. Didn't try it on my face, though. As always, your mileage may vary.
