best drugstore bb cream ?

Use vitamin C serum and moisturizer that should help get rid of the scars as well as Bio-Oil. The best BB cream to use would probably be Bert's bees just because it's natural. It looks very good on the skin. 

Try cleaning your face better. And using bunches of lotion all throughout the day. Dry skin can cause acne. Not cleaning enough to. Use hot watee to open pores to clean then cleanse with soap or whatever you use. Follow up with moisterizer soon after shower to help lock in the moister. Keep reapplying it all throuout the day. If that doesnt help/work try your diet. Your diet may be to blame. It can cause acne to ive heard. Only drink filtered water to help flush out the toxins and help clean your skin from inside out. A good example of a bad diet would be to much sugar for example. Ive heard someone say that can cause acne. Who knows what else can. Just best to eat really healthy and organic whenever possible and see if that helps.
