Face Serums

Hello ladies. So I’m looking into getting some face serums just for anti aging mostly. But they all say the same freaking stuff “best serum” “anti aging” “vitamin c” “hyaluronic acid” “stem cells” bla bla bla. But what brands are ACTUALLY going to help my skin in the long run? I don’t need help with acne and my skin tends to be very sensitive so seeing the word acid in all of them scares me. So if any of you know what that stuff does please let me know. Any kind of information helps. My head is just spinning from the hundreds of products.
