I've been loving bottom lash mascaras recently, giving my eye makeup a whole new dimension. The 2 I've been using are Clinique's Bottom Lash Mascara and Daniel Sandler's Baby Jet Mascara.
The brushes are completely different, with the Baby Jet probably quite suitable for short lash owners to use on their upper lashes too. Baby Jet is slightly more difficult to use on the lower lashes as the wand is so long, meaning you can't 'wiggle' as much as the Clinique. The result is more 'dainty' looking lashes.
I like both results and sometimes find the Clinique means I'm a little heavy handed, resulting in quite heavy looking lashes. The real test for this product is smudgeability. In this contest, Clinique wins hands down. This stuff does not move, whereas I find the Baby Jet moves at the sign of the slightest hint of oilyness around my eyes. If you don't have oily lids, you'll get a super performance out of either.
