Bride-to-be Lauren Conrad is known for her feminine style, her signature cat eye, and, of course, her glowing skin. While her fiancé William Tell may have something to do with her pre-wedding day glow, she recently revealed her other skin secrets.

The style star credits her flawless complexion to products from the emerginC scientific organics line, that combines potent botanicals and marine extracts into a powerful beauty and skin collection. Conrad’s favorite products from the all-natural collection is the emerginC scientific organics phytocell detox mask ($50; emerginc.com), a French-green-clay-based detox mask designed to draw out impurities, nourish, soothe, brighten, fight free-radical damage, and improve tone and texture. And earth-conscious brides, listen up: emerginC plants a tree using Plant-It 2020 for every product sold.
