Physician's Formula Eye Booster Instant Doll Lash Extension Kit is a two-step mascara product. In the package is a tube of mascara & a tube of fibre "extensions". Per the directions, you apply the mascara, tap off excess extension fibres from the brush (yes, DO this!), apply the extension fibres (they sweep on like mascara), then apply a second coat of mascara to seal the fibres. Repeat the steps for added drama.

The Good: The mascara alone is GREAT! For days when you don't want the over-the-top drama of the lash extensions, it does a fab job of lengthening & colouring the lashes. A bonus--it seemed to curl my lashes as it dried! The combo of mascara + extensions is dramatic. I found it added both volume & length. I've also used the "leftover" fibres (after the mascara was gone) with other mascaras.

The Bad: As you brush on that second coat to seal the fibres, there are of course fibres being picked up on the brush. The brush gets clumpy pretty fast (easy fix, wash it off) & the mascara seemed to dry up quickly.

The Ugly: For the love of all that is holy, TAP THOSE EXCESS FIBRES OFF THE BRUSH! Do NOT let them drop into your eye. They are very uncomfortable bordering on painful, & do not just wash away as your tears flow.

Picked it up at SDM, wait until it goes on sale for better value.
