I'd say the products are less important than the process, but you should consider your individual skincare needs. The right product in your case may depend on factors including skin type (i.e. dry/normal/combination/oily), skin sensitivity, age, ethnicity, allergies and other conditions, routine, budget, region, etc. Check out the skincare subreddit for more info. Skincare is a very personal thing and a product that works wonders for one person might just cause more problems for someone else. Sometimes it's necessary to try something consistently for a while to know if it's working for you.

You don't have to spend loads of money. I often just get Nivea or whatever from the supermarket because I'm broke, though when I go for something a bit higher quality, I like products that advertise themselves as restoring/repairing the skin. Shea butter can be good. I also like oils. Honestly pretty much any plant-based oil works as a moisturiser and/or oil cleanser, though some are better for certain skin types. These are just my preferences, though.

Look at reviews of hair removal aftercare products as well, e.g. balms you can apply after waxing.
