Review: Physician's Formula Eye Booster 2-in-1 Lash Boosting Eyeliner + Serum

I've had this eyeliner for 3 years now. I had to search for this particular liner for a reason not unknown to you, my readers. For some awful reason, still unknown to me, many liquid eyeliners irritate my eyes when used along my lash line. But it's only liquid eyeliners.

This led to me searching for a hypoallergenic liner!
