You AM routine is great because you are using a good sunscreen. You could increase it's anti-aging effect even further if you woudl swap you C-rush cream for a more concentrated vitamin C serum (for example, like this https://whatsinmyjar.com/product/paulas-choice-c15-super-booster or this https://whatsinmyjar.com/product/cerave-skin-renewing-face-serum-with-vitamin-c-and-hyaluronic-acid).
In the PM, I would recommend adding a retinol serum. Start slowly (for example, every other night, avoid using it under the eyes, unless until you are confident that you can tolerate it). A few options: https://whatsinmyjar.com/product/january-labs-triple-active-reclaiming-serum or https://whatsinmyjar.com/product/shani-darden-skin-care-retinol-reform-r for a higher concentration; https://whatsinmyjar.com/product/neutrogena-ageless-intensives-anti-wrinkle-retinol-serum for low concentration + budget-friendly). You'd apply it before the moisturizer.
