Trying to find a routine for aging skin with dry patches and fine lines

Hello! About one month ago I asked for your opinion about the skincare routine at that time, which included a lot (way too much actualy!) exfoliating. I had irritated skin, skipped some products for two weeks after your very helpful advice and sticked to only moisturizer and cleanser. The irritation is gone, I incorporated again Vitamin C and a niacinamide serum and twice a week a retinol product, but somehow my skin is not quite happy. In the morning it can feel a little dry, especialy around my mouth, but a little oily around my nose. And I don't now if it is my imagination but it seems my (enlarged) pores and fine lines look more visible lately and in general my skin looks a little dull in my opinion. Can you please advice me one more time? Thank you <3

A bit extra information: I am in my mid fifties, originally from Northern Europe, but I live now in a mediterranean country with lots of sunshine throughout the year, have fair to medium skin. Addition to my routine: every day I add rosehip oil from The Ordinary as a last step of my PM routine.
