For how cheap this is, I wasn't really expecting much of anything, but after two weeks of using this morning before mascara and at night after cleansing my face, I've noticed that my lashes are definitely thicker, softer, and slightly longer. I feel like it's really helped prevent shedding and breakage from mascara and makeup removal, and I can tell when I apply my mascara that my eyelashes look awesome nowadays!
