I would not use that. There are better options out there than that. One of the main things to remember about acne is it is simple just clogged pores. Keep you face clean and moisturized and that is the best thing you can do to get rid of it.
Neosporin helps to heal small cuts and scrapes. After popping a pimple, cleanse the area and apply Neosporin to help to speed up the healing process and prevent scarring.
Neosporin is not designed to treat the symptoms of acne. However, if you believe an acne blemish might leave behind a scar it is acceptable to apply Neosporin to it.
