What is in a wand? The different wands on mascara are responsible for the distributing of the actual product over the lashes….have a look at the pic and this will give you an idea.

A smaller wand will enable you to get into the base of the lash whereas a fuller wand will give you more volumptous lashes…

I use Estee Lauder Double wear on my bottom lashes and Sumptous extreme on my top ones! Oh the vanity…..
