How do I get rid of bumps and tiny bumps? ㅠㅠ It's urgent.

My tiny bumps and uneven skin texture haven't gone away for almost a year... Even though I'm a student, I've spent nearly 600,000 won on skincare at Olive Young, you know? ㅜㅜ But they still aren't disappearing... My skin type is combination to normal, slightly sensitive... I've tried balancing oil and moisture, exfoliating, and following the tips I saw on social media for getting rid of tiny bumps, but far from improving, it's just stayed the same... I want to get rid of most of them by the end of the vacation, so what should I do? What products would be good? What methods should I use? ㅜㅜ
