Eyelashes and eyebrows are the new frontier of aesthetics.
We were talking about this after dance class earlier this week. One of the younger women is in a college program to become a makeup person for the film industry. As part of the diploma, she has to take a bunch of basic aesthetician courses. Lotions and potions to grow eyelashes and eyebrows (primarily eyelashes) are huge. She noted that none of the teachers or students are actually trying the products.
Permanently stencilled/tattooed eyebrows/eye liner are also discussed in the program. They students have been discouraged from promoting these, as styles of eyeliner and eyebrows change every 3 - 5 years.
Brooke Shields has been part of an ad campaign re some product that grows eyelashes. I'm pretty sure she doesn't need eyebrow help.
