This eyeliner has been such a disappointment from Ilia. It does not sharpen well and leaves wooden fragments that scratch your eyelid. I gave up and changed to a different brand.

This mascara is amazing! It separates, lengthens, and defines my lashes beautifully without clumping or looking overly dramatic. I love how natural yet noticeable my lashes look. It gives me that perfect lifted, lengthened look, and it wears beautifully throughout the day. One of my new favorite mascaras!
