My eyebrows are a pain to tame! I don't like trimming my eyebrow hairs a lot because it grows back even longer. I used many waxes to try hold them down but they didn't last. This last for most of the day but it's easy to carry around and I apply it 2-3 times through the day but it works!
I haven't used this on my eyelashes as I never saw the need.
I don't use any eyebrow fillers/pencils as my brows are already full enough and this helps me keep them that way! Completely LOVE it! :-)
When I first started growing out my brows, I used this to help shape them. It is pretty much what it says - a gel in a mascara-type applicator.
Essence Lash and Brow Gel Mascara comes in a clear tube with blue accents, and the product itself is also clear. Unfortunately, this means that if you use this over a brow pencil, the colour ends up back in the tube, and it ends up looking murky and dirty even though it's just colour transfer.
The gel helps shape brows and tame flyaways, but doesn't add colour or anything - it's merely a tame and shine.
The applicator is a little large for the task at hand, which makes it easy to get product on your skin - this is easily removed with a cotton bud.
All in all, this is a very simply brow product, but it gave me a good idea of what i wanted, and eventually found in Benefit GimmeBrow (of which Essence does a decent dupe).
I didn't try this on my lashes at all, so can't comment there.
Tips: Super cheap, and good for fuller browed girls to help tame things.
