Works great and cuts right through mascara and eye makeup without having to rub. I have no eye irritation during or after use. This product works in a similar way that another high end makeup line eye makeup remover does. (One I always used in the past.) I need to shake together the the two liquids right before adding it to a cotton pad before wiping eyes clean. Clearly with the shaking and liquid separation there is some sort of oil and water mixing going on, but the final effect does not leave your eyes looking or feeling greasy.
