I LOVE ordering little things from Sephora. Right now their lip balm is like $3, and they have lip masks for $5. Sheet masks and things like that are cheap. I like to order from the site because they allow you to choose 2 samples and I love using them for gift bags.
Think about it as a way to emphasize your best features and draw attention away from blemishes and uneven skin.
You could star with your eye look. Maybe pick up an elf mini palette in neutral colors to practice blending the colors together. Maybe an eyebrow pencil, some mascara and liner.
You can use a concealer to cover anything you want to hide. You can also use a pressed powder foundation for this.
You can use blush, highlighter and bronzer to sculpt your face, but this takes practice and trial and error as far as the right product and colors.
