A number of vitamins fall under the vitamin B umbrella, including B-2 and B-3, both of which are used to treat acne. B-2 acts on the nervous system, and may have a calming effect, which can help to relieve the stress and anxiety that is believed to worsen acne. B-3 helps to improve healing, which may result in acne blemishes healing faster. A good B-Complex supplement formula should provide beneficial amounts of all important B vitamins.
