[routine help] starter routine for dry skin

I’m 23 and need help with my skincare routine. My skin is dry, but not too dry, and right now the only thing I use on it is the Neutrogena Hydro boost water cream. My skin has always been very sensitive to products, so I am hesitant to try too much at once. But I think I need another moisturizer from what I have read as well as a cleansing step and perhaps a serum. My first question is whether I should stick with the water cream or use what seems to be the lighter water gel. Then, what sorts of products do you add before or after those in a skin care routine? Likely looking at other Neutrogena products just because so far I haven’t had a problem with them irritating my skin. Would love any advice!
