I've reviewed enough mascaras in my time to keep my talking points brief on this one. Estee Lauder Sumptuous Waterproof Mascara ($27) delivers the sort of noticeably longer, more voluminous, fanned-out lashes I want from a mascara. The large brush, surprisingly, doesn't clump at all.
The only downside? Despite being a waterproof formula, it flakes and smudges around the 10+ hour mark. Because the benefits are so great though, I've been using it far longer than I should be. If you don't have uber-oily lids like I do, consider this one a must try.
