I've tried a few clean mascaras that didn't trigger my allergies, but none of them gave me the length and volume I wanted. That is, until I tried Beautycounter's brand new Think Big All-in-One Mascara. When I first received the mascara, I was immediately blown away by the sleek gold packaging that looks ridiculously beautiful in my drawer. Once I got past my obsession with the tube, I decided to give the formula and flexible brush applicator a try. And let me tell you, after one coat, my lashes looked longer, fuller, and clump-free. The more coats I applied, the more voluminous and lifted my lashes looked. Plus, they stayed separated even with multiple layers of makeup, which is a major win in my book. These 16 Mascaras Make Short Lashes Look Super Long While I loved how the mascara looked, the real test was leaving it on long term to see if it irritated my eyes. To my surprise, I was able to comfortably wear it all day as I stared at my computer screen and took a walk around my neighborhood without needing to rely on my emergency antihistamine eye drops. It also didn't smudge at all, even as I sweat on my walk. At the end of the day, the mascara easily came off with a cotton pad and micellar water. Courtesy Shop now: $27, beautycounter.com This true black mascara formula is carbon black-free, which the brand lists as a potential carcinogen and organ system toxin. Instead, it has tripeptide technology, which includes a blend of lash conditioners to nourish your lashes and make them stronger and healthier, and a mix of rice bran, calendula flower extract, and carnauba waxes to give your lashes lightweight volume. The mascara is completely vegan, cruelty free, and Environmental Working Group-verified. I've been waiting a long time for a mascara that would give me the length and volume I wanted without irritating my eyes, and the Beautycounter Think Big All-in-One Mascara does just that. If you also struggle with sensitive eyes, I highly recommend giving this brand new clean mascara a try.
