Acne Help

Hey guys, I’ve been trying to get rid of my acne using some of the tips I saw in the archives. I’ve been using a face wash, a salicylic acid based astringent, and a salicylic acid based moisturizer at morning and night. I went and bought some B-5 as well. Now what would be the dose I need to take of the b5. They came in 50mg capsules. I appreaciate any help you guys can throw my way.
