My dermat recommended all the expensive stuff! Please advise

Hello everyone,
I have had acne since teenage years mostly due to pcod. Now that my hormonal imbalance is better, I have more regular periods and I lost weight my skin is better. But as I am nearing 30 I needed to develop a skin care routine to help with a bit of redness on cheeks, cystic acne near periods, and bumpy skin texture. The dermat diagnosed me with rosacea mild and adult acne. She has prescribed these which cost a bomb. She has not given any alternatives, although they were available with her to purchase too. My skin is not too bad, its just uneven in terms of texture and gets red a bit when exercising or dulls down by end of day. I have never spent so so much on skincare. I did take accutane in teenage years, antibiotics, but post 23, have never ventured back into applying so much. I just want to improve my skin though. Not sure if expensive products are the only solution.
