Is there an ultimate "age gracefully" skincare method?

I am wondering what your take is on the "best pay for your buck" skincare regime if the goal is to look the best you can into your later years? I don't mean just in terms of money, but the time & effort too. My issue is that I have good skin now (mid 30s), and I don't know what my skin concerns will be when I get older. What is the "gold standard" for a skincare routine for milder, more graceful ageing? I know I can't prevent ageing, and i don't want to, but looking good while getting wiser is appealing to me:). I mostly mean products, but not opposed to procedures (non surgical at least).
