I use Eye Envy on Chanel with her long hair - both mine love to play outside alot and they tend to get dust etc in their eyes - Eye Envy takes the stains almost completely away within a week - I love the stuff. I just always forget to use it. you have to keep it refridgerated too - which is WHY I always forget to use it.
I tried the eye pads and took it back within the 2nd week of buying it - I saw NO change
