Buxom is a brand from the Bare Essential Cosmetics Company. This mascara is exclusively sold at Sephora. The cost is $22.00. This mascara has the ability to offer volume, lengthening and defining. It has a very unique brush which expands and then shortens. The non-expandable brush defines, separates and adds length. Once you expand the brush it adds volume. I actually just tested the extended brush in the pictures. I love volume, but as you can see it also gave great length to my non-existent lashes. Their was no clumping or flaking. The shorter version of the brush is great as well, it gives a very natural finish to the lash. I love that the black in the mascara is a deep black, your lashes will stand out. It lasted a good 10 hours before the lashes started to droop. It was very easy to wash off with cleanser. It did have a faint smell but quickly went away after it dried. There are no synthetics dyes, sulfates or parabens Overall I give this a 4 out of 5. It was a good mascara.
