No idea where to start

34 years old and for the most part have had decent skin. As I’m getting older I am starting to see fine lines and a lot of redness. Idk if my redness is rosacea related or just red. I don’t have any issues with acne, I feel like my pores are slightly large and my skin is dry. I honestly find skin care overwhelming and have no idea what I actually need. I see people posting about vitamin c, tret, niacinamide, hyaluronic acid, etc etc. and I am just like…wut??

I am looking for recommendations on products others have used for similar issues that they have found beneficial. Thank you!!
