How Jennifer Lopez Remains an Age-Defying Unicorn

POPSUGAR: You always serve up serious glam, but Las Vegas seems like it calls for extra glitz. How did you intensify your beauty look for the Sin City stage? And how do you keep it from melting off while you're dancing?

Jennifer Lopez: So true! If not in Vegas, where? Between Rob Zangardi [wardrobe] and Mariel Haenn [wardrobe], plus Mary Phillips [makeup], Tom Bachik [nails] and Lorenzo Martin [hair], I am so fortunate to collaborate with some of the top creative visionaries in beauty and fashion. The results you'll see are flawless attention to detail and countless hours spent planning with this talented group of people. Touchups are always necessary between performances, but a setting spray, waterproof mascara, and long-wear foundation are crucial from the start to make sure meltdown is kept to a minimum. I really like the L'Oreal Paris Infallible Makeup Extender Setting Spray ($17) and Foundation ($12). Expect to see lots of lashes, and a spectrum of lip color.

PS: Your eyelashes are so long that I could see them from the audience. So I have to know: what are your mascara application tricks?

JL: Primer goes first, then after a few minutes I'll coat with color. I usually opt for blackest black and comb it out while coating, so lashes are bold but never clumpy. I love L'Oreal Paris Voluminous Superstar Mascara ($10) right now.

PS: I am fascinated by your skin care routine because your complexion is always so gorgeous and glowy! What's the secret?

JL: My makeup artist always says that people should think of their skin care as their makeup, which is so true. I'm religious about SPF use and really think that there is no other way to maintain a healthy glow — which is kind of ironic because in our younger years we always want that instant gratification of a tan. I also think that regular workouts, lots of water, and fresh foods all play into the quality of skin's appearance, plus the obvious removal of makeup at the end of the day. Without all of these, you're not setting your face creams or facials up for success.

PS: Your hair has amazing texture — that effortlessly cool, relaxed wave. What products and techniques get it to look that way?

JL: A lot of them — and, for appearances, a professional! My day to day is fairly simple. I like a deeply hydrating shampoo and conditioner, since my hair gets put through a lot on set, and, if I have the time, an oil-based deep treatment like L'Oréal Paris Advanced Haircare Extraordinary Oil Curls Re-Nourish Mask ($6) is a nice treat.
