Tips on Accutane?

I started accurate roughly 3 weeks ago, and my makeup has SUCKED ever since. One of my biggest issues is sunscreen. I’ve never worn sunscreen before starting accutane (bad, I know.. no judgement okay?) and I’m currently using the neutrogena hydro boost sunscreen. However majority of my base is oil based products and this sunscreen isn’t working for me. Should have predicted that but I was intrigued by the hydration aspect lol. Does anyone have any affordable options for sunscreen? I’m not opposed to higher end expensive products, but I would prefer to keep majority of my routine budget friendly as I am a student.

Furthermore, even without sunscreen, my skin is DRY. I’m using a super high duty moisturizer so that isn’t the issue. It’s just the makeup clinging to dry patches that don’t even exist before makeup.. for reference I’m using nars pot concealer, which causes this issue, and in addition I use the L’Oréal true match foundation — I’ve tried them together, seperate, and the issue still persists. It seems to be more of an accutane issue rather than a product issue. Does anyone have any suggestions? I really love the nars pot concealer and don’t want to switch up on that if I can absolutely avoid it, but maybe a primer or something to help with the dry patch clinging? Thank you guys 🫶
