Alert: We Just Found the Beauty Sponge to End All Beauty Sponges

For the past two years, I have used my beauty sponge of choice (I'll let you guess which one) to apply every single one of my makeup products. Foundation, concealer, bronzer, blush: My trusty sponge can handle it all. Streamlining my makeup application process has significantly expedited my routine, and I have remained faithful to my singular sponge ever since—that is, until two days ago.

Over the weekend, I got my hands on the new beauty sponge from Sigma, which was strategically engineered to surpass all others. Sigma's co-founder Simone Xavier brings to the table not a makeup background, but a PhD in molecular biology and a steadfast commitment to science. There are dozens of beloved beauty sponges on the market right now, but Xavier had a feeling she could design something better.

"When using a regular sponge, I have always encountered challenges, such as applying foundation around my brows and lips, or not being able to reach the sides of my nose," Xavier said in a press release. "I have also observed many users 'pinch' their rounded beauty sponges to try to get the edges they needed for a more precise makeup application." Taking these observations into account, she entered the lab and emerged three years later with the Sigma 3DHD Blender ($15), an angular sponge with three flat surfaces and one round surface, each designed to apply a specific product to perfection.

The science sounded promising, but would Sigma's new blender live up to the sponge I've used and loved for years? Keep scrolling to read my honest review.
