ok so i'm an 18 year old male, i started getting acne when i was 16 and then at the end of april this year i started taking accutane. i took it for 4 months and it completely got rid of all my cheek, neck, back and chest acne. however it didn't get rid of the red marks which i had with the acne so they're still on my cheeks and neck. My skin is perfectly smooth with no lumps or acne but i have lots of flat red marks and dots all over and i have no idea what they could be. Can anyone help? Thank you
