Great design unimpressed with formulation
Overall, I was unimpressed with this product. The formulation was underwhelming and a bit drying, not harsh but also not the satin feel I prefer. The neutral color hardly showed up on my skin. It was not pigmented enough in my opinion, at least not for deeper tone skin. Maybe this may work on fair s...

Why would you change the applicator

Comments about SPIKED
I've been using MAC eyebrow pencil ever since I was in high school. I always loved the longevity of the pencil and how I would get so many compliments on my brows. It was easy to use and lasted a long time. Now since they have made the pencil thinner, it doesn't last nearly as long. It's always breaking when I apply it to my brows I use light strokes and it still breaks. The old applicator was thicker and worked way better. Why would y'all change it! I have went through three in the past 2 months . Now I have to find a new eyebrow pencil and I am honestly so sad. MAC was always my go to and I never used any other eyebrow pencil. BRING BACK THE OG MAC EYEBROW PENCIL
Disappointed!
I am a MAC lover and this is the first product that left me disappointed. The product breaks easily because of how thin it is. I've adjusted by twisting a tiny amount from the end of the pencil and working with it that way. I do like the color STUD.

Comments about SPIKED
I've been using MAC brow pencil in spiked since around 2003. I used it so much I would buy several at a time so I had back ups everywhere just in case. Ain't no way I was gonna be caught without brows IYKWIM. Now with my most recent purchases I noticed several things: new packaging, with obvious less product and what looks like a formula change that does absolutely nothing. I thought I was imagining things but after going through all my backups in just a few weeks, I was forced to search for an alternative. The product used to last me months and now it's crazy how it's gone in like 2 weeks. The product itself seems to have less pigment payoff and doesn't glide on as smoothly as it used to. MAC - listen to your long time loyal customer base. We are trying to rock with you all the way but this along with discontinuing cult favorites (studio finish concealer, select cover up concealer, studio fix fluid ) is going to send the company to its demise. By the way, a good alternative for this brow pencil with formula closer to the original is NYX.
Precision brow pencil at its best.

Fantastic brow pencil for adding fullness to thin brows. The precision size of the tip means you can accurately draw on individual hairs for a more natural and realistic look. Downside is it takes longer than a simple brow gel and application is for a more experienced individual
