I then applied an eyeshadow primer (I used ELF) and a base shadow that is similar to my skin tone (I didn't add it, as you can use any shade. I used an ELF one from a super old palette because it works for me for the time being).
I applied the base shadow almost to my brow and all over my lid. It'll totally help with blending the matte shades especially. Those can be such a b*tch.
