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...

Comments about SPIKED
Bring back the pencil!! We do not want this mechanical stencil. The pencil was thicker and it lasted longer. The product is already expensive, and you all change it and give us less of it??? It's not as sturdy and the pencil. Bring back the eyebrow pencils!! I had to find a similar shade from another store to keep from buying this one every month!
New Formula Terrible

Comments about SPIKED
I have been using Spiked on my brows faithfully for the past 16 years and this new formula is the demise of the product. As others have mentioned, the product just crumbles away when applying. Due to working remotely I don't even apply daily anymore and still only get 1 to 2 uses per pencil. I literally found an old spiked that I had to use in a pinch to finish my eyebrows mid makeup because for the second time this new formula failed me. I'm officially on the market for a new brow pencil. MAC if you bring back the original let us know.
Love the new improved Pro Brow Definer

Comments about BRUNETTE
Way to go MAC! Thank you for making improvements to this eyebrow pencil. I love the finer tip, making the fine-like coloring on the brows instead of coloring the skin under the brows. I also love the new transparency of lid for the the brush end. I never confuse the ends now. THANKS MAC!
Breaks Easily!!

Comments about ONYX
Would not recommend. Breaks off way too easily. Did not even last a week because it kept breaking off. Please update the design or thickness of the pencil.
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.
