Acne / skin care

I’ve been suffering with acne since I was 14. Now I will say it has gotten a LOT better since I was 14 (19 now). However it just won’t go away. Could it be I’m still young and this is a normal thing to happen ? Could it be that I have super sensitive skin? My skin care routine is just scrubs and mask throughout the week , nothing drastic. Even though my acne has gotten so much better it won’t fully go away. Help?
