Sebaceous filaments and texture?


Hey all- I'm super new to skincare. Super new as in don't have a routine at ALL. As I'm getting older I'm starting to have serious texture and pore and/or sebaceous filament issues. I have a total crater nose! I feel sooo self conscious as I already dislike my nose due to its prominence and I feel like these holes are making it stand out even more. Does anyone have any suggestions on products and/or a routine I should be following? I've tried researching and just get overwhelmed.
