Alright, so I've been messing around with the Penultimate Brow Marker lately. I am in no mood to go through the past several pages, so I'm sorry if I'm repeating anything that's already been said!
It is AWESOME AWESOME. It goes on super precise and super smooth and its much easier to do than the eyeliner since brows are generally alot less precise and not as fussy as liquid eyeliner. Pressing harder gives you a thicker line, while light sweeps will give you a nice thin line.
It's the perfect shade for dirty blonde to dark brown to red, but I have to tell you that you have to have WARM toned hair, preferably with auburn undertones. I would also suggest that you only use it if you are an NW as well. I have tried it on several people and it looks best on those skins/hair types.
I tried it on an NC15 girl with dyed black hair and it looks SO obvious. Like you could tell she is wearing some kind of eyebrow color in the definite wrong shade. This is the biggest drawback, the single shade in 'Universal' which is honestly not universal at all. Hopefully we will get a cooler blonde, a cool taupe, and a deeper brown sometime.
The BEST feature of this formula is that it is water resistant. It is BUDGEproof once it dries. I let it dry on my hand and it wouldnt rub off, my hand was red and I still had strokes on my hand! Geez!
If the shade suits you I would definitely suggest trying it since the application is a breeze and the product lasts well on the skin. I already have several Clinique and Estee girls putting in orders!
