  • "This product is one of the most recent mascaras that just came out from Mac. My lashes are usually straight and need some volume. But with this mascara I was able to get every single lash and coat it equally and pretty much get the perfect application . The two wands help you choose and match the perfect way to apply your mascara. As well as gives you more volume and length." in 6 reviews

Great mascara with 2 brushes, I love the way it accentuates my lashes, especially after using the Rodan + Fields Lashboost which has grown my lashes ridiculously long. It makes my blue eyes POP! I recommend Bold & Bad Lash. Only downside is it's a big mess to remove. Takes more than a few wipes n washes. Pricing... Not so hot. M.A.C Cosmetics Bold & Bad Lash Mascara

Ok now MAC outdid themselves with this one! You are literally getting TWO mascaras in one! The main wand instantly gives your upper lashes length, volume, and a thickness, that is absolutely bananas because the difference of before and after just ONE coat is truly crazy because it doesn't even look remotely like the same lashes! AFTER JUST ONE COAT! That would've been enough to sell me on this product alone, however, MAC being the cosmetic geniuses that they are, decided to take it even one step further and included another wand screwed into the top of the big wand. THIS wand is made specifically for your dainty lower lashes because of it's tiny size & smaller bristles, it is made to coat, seperate, and lengthen your baby lashes, so that they look as amazing as your top lashes! Using [product:mac-bold-&-bad-lash-mascara] I have literally put the false eyelashes away and do not feel the need to wear them EVERY single time because Mac's B&BL Mascara brings out the absolute best of my natural lashes and makes them look so good that they only LOOK like they can't possibly be natural, but they are! -AND THAT MY FRIENDS, IS THE BEAUTY OF IT! 💋

I’m a big fan of this mascara! The dual chamber packaging is amazing. The mascara contains a large brush for voluminous upper lashes and a smaller brush for a defining smudge proof lower lash!

Favorite mascara. Packaging is cute and I love that it has two brushes so you can get top and bottom lashes with ease. This mascara brings more life to my eyelashes. Well worth the price!

Best Mascara that I love. The one thing I love about it is the smaller wand because it makes it easy to do your bottom lashes as well as the inner and outer corners with ease.

I wouldnt say the larger chamber does anything revolutionary to your lashes. It is black and provides your lashes with a whispey sort of volume, just like any decent mascara does. However, the small chamber is a GAME CHANGER. SOOOOOO great for getting your lower lashes. They stay separated without looking clumpy or gross. Love it!

I have a new holy grail mascara. I have very long lower lashes and never new what to do with them until now! What an amazing product, my lashes look better than they have in a while! Would definitely recommend especially to those who do not wear falsies! UPDATE: I still love this mascara but I know have a new holy grail; however I still use this mascara first bc I always use two mascaras if I am not wearing false lashes

Been on a hunt for a good mascara! Would this be on your top three for mascaras? Does it make your eyelashes look longer and fuller?
