Hello there, if you're new to skincare, the first thing you'll need to do is to find out what skin type you have. It's very important to have a confirmed answer before you venture into the rest.
A basic skincare routine includes a cleanser, moisturizer and SPF (sunscreen), they won't cost you too much if that's what you're worried about. To further filter what type of products you may want, maybe think about what concerns you have or what improvements you'd like to make for your skin.
