If a human bats her eyes at you, it's considered flirtation, but only if the eyes' lashes are arranged exactly according to the standards of the International Society of I'm Flirting With You. Send the right signal with today’s Groupon: for $125, you get a full set of eyelash extensions at Integrity Lash in Pasadena (a $300 value).

Integrity Lash's team of stylists––under the watchful eye of lash professional Tussanee––expertly augments peepers with hand-applied lashes in one of four private treatment rooms. With a selection of varied curl shapes, lengths, and thicknesses at their disposal for extra dimension, stylists outfit eyes for any occasion or look, from natural, everyday glamour to the swimsuit portion of a job interview. After carefully considering eye shape and lash direction, they affix a microfiber extension to each lash, plumping up lash lines with a total of 60–100 strands per lid. When the two-hour session is complete, lashes are full, lush, and strong enough to withstand showers, pillow friction, and Martian sandstorms for four to six weeks. To maintain a healthy set of fringe, the team recommends a touchup after four weeks. Integrity Lash's aesthetic expertise also translates to its vintage-inspired space; the boutique’s pink velvet sofas, brocade accents, and chandeliers strewn with crystals evoke a regal, retro feel, transporting guests to a different era without unraveling the delicate fabric of time.
