For those of you with clear skin, please help?

Ok so I have daily regimen, I wash my face with Aveeno Clear Complexion foaming face wash, then I use Neutrogena Triple Action Stress Control Toner, then I finish with Aveeno Calming facial lotion. My face is clear except for those occasional zits that come at the most inconvenient times. But the problem is that even though I do all that twice a day I'll get that zit, it'll go away and it'll leave a little small tan-ish "scar" thing! I have no idea how to get rid of it and it's really annoying! So if anyone knows how to get rid of stuff like that and get COMPLETELY clear skin that'd be awesome if you could share your advice and tips! Thank you :)
