How long do pink acne scars last?

I know they never actually go away ..but how long untill they fade? ..its been a week or so, and i have been using tea tree oil face wash, vitamin e and aloe vera for the full week.help?!|||as i can see that u are using nice products, i use the same. pink ones ---i suppose they arent the deadly ones so they would take 3 months to fade. Good luck.
