What is the best way to get rid of a pimple without leaving a scar?

Some people tell me to just let it go away on its own but other people tell me that if i do that i could get a scar. Then there is other people that tell me that I should pop it and put alcohol on it afterwards I dont know what to do i need help.|||I have found that waiting until it is ready and getting the whole lot core and all out will leave you without scarring.|||MERDERA BLEND IT IS ADVERTISE YOU TV. Costly but works -- as soon as you get the scar and old scars. You may need more than one tube.
