So I've known for a while that my eyebrows desperately needed to be filled, since one spot in particular has been looking patchy. I've tried pencils but it always looked WAY too dramatic and I felt ridiculous.
I read reviews for this and decided to give it a try. I bought the dark brown (after holding the computer screen up to my face and asking my extended family which was the best match), which I was nervous about, since I'm not particularly dark, but this was perfect for my blonde-haired-but-brown-eyebrowed face.
It's WONDERFUL. Very subtle, you have excellent control over how much you apply, and since it comes with the two colors, you can blend to get a perfect match. After I've applied, you can't really tell my brows have been filled, they just look slightly fuller and more even. It's perfect.
Make sure to buy a good eyebrow brush to apply, though. I tried an angled eyeliner brush at first, nope nope nope haha.
