Reg: Acne scars treatment. See results!

I am 28M working professional. I have very bad diet habits , I consume less vegetarian foods. I had lot of acne breakouts in past, I couldn't consult a doctor as the acne always went away in few weeks. Eventhough the acnes went away, they left behind acne scars and now that I look at the mirror, I find many scars on my face. After a quite extensive research on google, I found out that I had all the types of scars:boxscars (approximately 4) , toothpick scars(approximately 3), blemishes and what not. I think I have few active acne as well.  Google suggests various surgical procedures like microdermabrasion, chemical peels that needed to be done by a professional multiple times to get better results. I am not willing to undergo any of the surgical procedures at the clinic. I just want to know if these acne scars can be reduced significantly with over the counter doses/ointments. Also, if there are over the counter doses, please let me know in how many days I can expect to see results
