Physicians Formula Eye Booster™ Lash 2-in-1 Boosting Eyeliner & Serum, Ultra Black

I will always give a product five stars, if it works. Physicians Formula Eye Booster 2-in-1 Lash Boosting Eyeliner + Serum protects my sensitive eyes. No irritation. I like that it stays on all day and does not smear. This is a great eyeliner. My eyes love it. I would definitely recommend buying this eyeliner, if you have super sensitive eyes. It works. It really works.

I loved this product in the "ultra black" shade.. It is the only eyeliner I have found that does not transfer and ruin my eye make up once I blink, and it dries like lightening! Hope they never stop making it.

Loveeee it!!!! For the price... this eyeliner is amazing! Shame that is out of stock... if you like the black finish...you have to buy the "ultra black" shade... the "black" one...is more like gray color....also like the brown color...so far...this is may favorite aye liner ever!!!

The brush is great for getting a thin or thicker line close to the lashes. It stings if I accidently get it in my eye, but is otherwise perfect. And, it comes in brown!

I'm impressed with this eyeliner. I prefer it over the prestige brands I've tried : MAC, Clinique, Kat Von D, Stila. The color is a deep black that's neither too matte nor shiny. . The brush is what makes this product great. It is fine-tipped with just enough flexibility to create a precise cat eye. I feel the felt tip liners on Kat V D and Stila are too bulky to create a thin, tapered end of the cat eye. The formula applies evenly with no skipping or bleeding on my eyelid, which is a problem I've had with MAC and Clinique eyeliner pens. I purchased the brown color about a year ago and it's almost used up. I plan to stock up on both colors. I like used black on my upper lid and brown to lightly line the lower lid.
