I love a multi-purpose product, but sometimes products aren’t always marketed for the things you can actually use them for. Eyeshadow being one of these, can you use eyeshadow to fill in your eyebrows? Yes, you definitely can. Eyeshadow actually has a few other multi-purpose uses as well, such as blush, highlighter, or bronzer. However, we’ll keep things simple today and stick to filling in the eyebrows with eyeshadow.
