Simply put, this is a great product.
I have blonde hair and really light, thin eyebrows with gaps throughout. From a distance it looks like I don't have eyebrows at all.
I've tried a lot of products that have looked really unnatural or too dark, but the blonde tone of this product is perfect for me.
Not only does it fill in the gaps and add a bit of colour, but it holds the eyebrows perfectly in place for a really polished look. It lasts until I wash my face.
Overall, I'm very happy with the Colorstay Brow Enhancer and I will definitely buy it again.

Bought the shade in dark brown. Looks super unnatural on my brows. This is also almost twice the price of my etude house HG brow pencil, hence i really had high expectations. Will not repurchase again.

The concept of this product is great, but the reality...not so much. The tinted wax does nothing to hold the brows in shape and the tip of it is much too big, making it very difficult to apply precisely. I'm a big fan of a well-drawn, defined, and clean brow and this just isn't capable of achieving that. The wax goes on patchily and does not provide any definition; rather it achieves a more haphazard, messy look. The highlighting end is fabulous, however I wouldn't repurchase solely for that as I can easily achieve a highlight with a different product.

I would recommend this to someone who already has dark brows who might just want to define and darken them a bit more. As mine are very fair and sparse, this product just doesn't do it for me.

The shade is quite nice but when applied on my brows, it doesn't stay on long. Even when I put primer over it, the color just rubs off. I just use the highlighter instead. Unfortunately, this product doesn't work for me.

I have sparse eyebrows, thin eyebrow hair and as a teenager of the 90's, I over-plucked my eyebrows, so I have a lot of bald spots. I now prefer my eyebrows to be a straighter, fuller and in slightly thicker/wider shape. This requires me to color in parts of my skin and most eyebrow pencils leave the bald patches too pigmented, so my eyebrows look unevenly dense. Eyebrow powders don't last long for more than a couple of hours and I'm never able to get a clean, defined edge. Separate eyebrow waxes end up erasing all the hard work I put in to shading in my brows.

So I really really really like this product! The waxy texture of the eyebrow color allows me to fill in the bald spots without worrying about certain parts being too pigmented. I can apply this with fairly heavy hand and still get natural looking brows. Since I still have my other eyebrow pencils, I do touch up my edges with them, as this product is better at filling in large areas of skin rather than defining.

In terms of my coloring, I'm pretty pale, with dark brown hair. I was only able to find the light brown color for the pencil and it's actually the perfect color for me. My eyebrow hairs blend in well with wax and my brow shape looks good 8 hours later.

HG alert!!! Finally, a brow product that does not look fake , keeps my brows in place and stays on!! The only problem with it is the gel can sometimes dry and leave a couple of white patches but that is easily fixed. I have previously used Urban Decay Brow Box (my former HG), Benefit Brow Zings, MAC brow pencil, Laura Mercier Brow Definer etc and this beats all of them in terms of looking natural and lasting all day. Will continue to repurchase. Thank you Revlon!

This is a great budget brow enhancer. I have very sparse eyebrows and a lighter skintone, and it still looks quite natural (I have this in blackened brown/taupe). The highlighter is subtle and versatile as well, though I would not use it liberally on other areas of the face, as it's pretty pink. I would definitely purchase this again, as I find the dual-purpose packaging pretty convenient for traveling/makeup bags. The only complaint I have, however, is the twist-up functionality. It makes the makeup sticks somewhat unstable, as they tend to wobble inside the packaging. It is very noticeable with the highlighter end. But overall, good value/convenience for the price.

This product is mediocre and looks really fake without using a brush to brush out the brows. I bought two colors: light brown and the black brown one! Because it is a hybrid between a pencil and a wax, it tends to look really thick and fake. It's really hard making it look realistic especially since the pencil itself is pretty thick so making thin strokes is impossible. I find that the product does say in place all day unless you touch your eyebrows. Also throughout the day I find my eyebrows to look oily and shiny.


Pros:
Hybrid between wax and pencil
Comes with a highlighter
Long-lasting


Cons:
Smudges
Fake looking, need to use eyebrow brush
Hard to make thin strokes
Not a lot of product
Expensive for drugstore brand $8-10


Would I re-purchase?
No No NO!! I purchased two of these, I'm sure for $20 I can buy a product way better than this!!! Gave it 2/5 because I really wanted to like these since I bought two and they were pretty pricey :(

About me: NW10-15 (neutral-cool toned, very fair), blue eyes, Color season is True Summer, Baumann Skin Type is OSPW.

BEST BROW PRODUCT EVERRRR. Caused me to stray from my Anastasia brow powder. It's a tinted wax pencil, so it shapes, fills in gaps, and holds all day. Additionally, there is a tinted highlighter on the other end. The highlighter leaves much to be desired because it is stiff and tugs, but it actually does stay on all day and can even be used as a base when in need.

The Blonde shade is perfect for blonde and light brown brows. I have brown brows and brown hair, but I like to use this when I am NW10 because its less harsh than my actual color. Comes with a golden highlighter.

The Light Brown shade is perfect for brown brows, it's slightly ashy, which is great for me, because most people don't have red-brown brows, so I don't know why they even make pencils in that color. I wear this when I am NW15-20 in the summer. Comes with a champagne highlighter that is slightly bronzey.

The Medium Brown shade is more like the typical reddish-brown found in many brow products. I keep this shade around for when I am going out, as I like to have strong brows for an evening look. Comes with a pink highlighter.

EDIT Jan 2013: I lowered this product to a 3, as it is no longer my HG brow product for two reasons: First, it doesn't last as long as some of the other products I have tried, I notice it fades after a few hours on me. Second, you can't sharpen the point of the brow wax to a fine point, therefore, it is more obvious when you draw that it is not fine hair strokes.

I've bought about 5 of these already: 1. because it's a great versatile product. I can fill in my brows and the waxy texture holds my unruly hairs in place. The highlighter is OK too, it works as a highlighter and brightener for under the tear duct. It's a bit chalky but it is not overly shimmery, which is a problem I see with many highlighters. and 2. Because they run out really fast: there's not much wax pencil end for the buck IMO. I'll keep purchasing until I find something better. I like the range of colors: the browns tend to be neutral with no red undertones. This is true for the blonde, medium brown and blackened brown, to my eye. I've tried all these colors and somehow they all work with my fair complexion and dark brown sparse brows.
