What treatment should I do for acne-marked skin? (with photo)

Ever since I was in middle school, I have had small acne on both cheeks very often, and purulent acne has often appeared during my period.
 
I have lived with this skin pattern for 13 years.
 So, I always had red marks on both cheeks like in the picture.
 But these red marks. There are times when it suddenly turns into an itchy pimple.
 
These days, I've been consistently applying Noscarnagel and Acne Ointment, so it's a little better than before, but I still want to completely improve it.
 
What kind of treatment should I get for skin like this??
 I'm a bit worried because I saw on YouTube that if you get laser treatment carelessly, your skin will become thinner and more sensitive, and it could be poisonous.
