Hi, I have recently started in the last 2 weeks taking vitamin A supplements and also vitamin b5 Pantothenic acid, for my acne, I have oily skin and my acne is mainly just whiteheads around mouth and jawline.

Around how long should I begin to wonder if these supplements do in fact help and take effect?

Also could u recommend anything else? Could my spots be to do with my diet? The picture below there are 2 big spots near my mouth that are very swell and sensitive

Thanks
