What makes this applicator so different – besides that it’s a fab hot pink shade – is that it’s elliptically-shaped with suede texture. The rounded curves of the brush supposedly help achieve a clean, even finish with no hard or visible edges, while allowing easier access to the under the eyes area and the sides of the nose.
So basically bouncing or stippling the BeautyBlender sponge on your face is supposed to help blend in foundation or concealer without lines and streaks. I haven’t tried this myself, but I’m guessing it def works better than fingers (which is what I use for the most part!), though I’m not sure that it’s that much different from a triangular sponge. That said pink suede seems pretty hard to resist:-).
