the best thing i can tell you is to see a dermatologist...(i know it's expensive)
you could just keep washing it, try to dry out all the acne
never pop it, it will cause scars( i learned the hard way)
try to find a way to gently lighten the red scars, try honey day and night,
try apple cider vinegar mixed with water, you can mix honey and apple cider vinegar and use it day and night, don't be harsh it'll worsen, i have acne and acne scarring and it's slowly but surly working... to be honest tho it's not that bad it's nothing to be worked up about i could barely even notice it lol.
