An undertone is the color beneath the surface of your skin, which never changes (even with a tan). There are three types of undertones:
Pink/Cool
I see red or pink undertones around the perimeter of my face and neck.
My skin burns easily, but barely tans.
My skin looks better in silver jewelry than gold.
Neutral
I see both pink and yellow undertones around the perimeter of my face and neck.
My skin sometimes burns and sometimes tans.
My skin looks good in both gold and silver jewelry.
Yellow/Warm
I see yellow or golden undertones around the perimeter of my face and neck.
My skin rarely burns, but tans easily.
My skin looks better in gold jewelry than silver.

— Beth T. (5/5)
"This is my third purchase of Brow Up. I have loved the product prior but this balm is coming out clumpy in spots sticking to my brow that I have to fix"
— Amy F. (1/5)
"No hold. Barely any tint. Dried up quickly. I was expecting more. The only good thing is that the brown/black was pretty dark and cool-toned."
— Cynthia (2/5)
"Have tried a few of the brow balms with wands, and this is the best - provides enough product to actually fill in your brows without having to also use pencil, the smaller wand I makes it easy to apply the right amount, and the color is perfect. This is my second purchase of this balm"
— Angie C. (5/5)
"works great to add some definition to my brows while still looking natural! My favorite brow brush I've found so far."
— Christine L. (5/5)
"I love this eyebrow gel and this brand in general :) highly recommend"

"This is my third purchase of this product; twice in this color. I have graying hair, so it took me a couple of tries to get it right. Great formula and natural coverage."
— April F. (5/5)
"I repurchase this frequently. It does get a little dry throughout the day, but I prefer that to a wetter brow formula."
— Mariya N. (5/5)
"Love this brow balm. It's not quite a laminated effect, but definitely makes my brows look fuller, and has just enough hold to not be stiff. Love that it's still a very natural look."
— Jessi (5/5)
"Nice color for blondes who want to fill in a little darker but not look crazy."
— Caroline G. (4/5)
