Best basic Skin care items for woman in 30s

Embarrassed to post this but basically I'm a woman in my 30s with no skin care routine. I occasionally moisturise but that's about it, I have started to notice more signs of ageing and want to start taking better care of my skin but lost as to where to start. I would say my skin is on the dry side with no issues with break outs. I also dont wear make up , if that makes a difference. I'm looking for recommendations of basic (hopefully cheap) products I can get in Ireland to get me started on taking care of my skin. So girls what are some items you love and would recommend
