Expensive mascara, lashes, powders, sponges, tweezers, setting sprays, lip liner, and eye lash glue are usually never worth it. Products I’ve found to be worth it are eyeshadows (especially foil or glitter ones), foundation, primer (eyeshadow and face), skincare, brushes, eyeliner, lipstick (especially liquid ones that dry matte). Good brands I like are too faced, urban decay, Mac and color pop (color pop is just name brand but easy on the wallet) Hope this helps!!
