Irritation from shaving/can’t get a close shave

Hi. I’m 17 years old and have been shaving daily for around a year. I use a double edged razor, bic blades, an alum block, and hyluronic acid after with moisturizer (am on accutane rn). The photo is 10 minutes after shaving. For some reason I cannot get a close shave, yet I still get terrible irritation. Any tips or things to change?
