The all in one mascara promises to separate, lengthen and amplify lashes. The lash catching brush has over 200 bristles that equally spreads out the buildable formula. The tapered tip can be used for the inner and outer lashes along with the smaller lower lashes. The voluminous formula is lightweight and long wearing. The mascara went on easy and gave me a false eye look. The formula didn't smudge or cause flakes but if you blink to quickly the formula ended up all over my eyelids. A definite new favorite mascara.
