I don’t use foundation either and get compliments on my skin. Foundation (liquid, cream or powder) always made me look dried out. Look up “clean girl makeup” - the terminology is controversial but the concepts are useful. Just make sure you’re decently moisturizing, maybe a hyaluronic acid serum in the winter under your regular moisturizer, and then the under eye concealer. Sunscreen, and then a glow serum or cream/liquid highlighter (people like the Glossier oil serum, I use one of the Fenty highlighters in a tube). Then a little blush or bronzer, mascara, lip, done.
