How do you lighten a pimple mark on face?

U should use Bio-oil.it's gr8 for scars and it worked gr8 for me.If u can't get that u should use vitamin e cream/oil.The oil is probably the best.make sure u read up on them first and if u do decide to use them make sure it is applied 2-3 times daily to c quick results.Just a tip don't use home remedies cos most don't work and it could b harmful if u don't know what u r doing.
