Jennifer was glowing as she hit the red carpet with her fiance Justin Theroux at the premiere for his new show 'The Leftovers' in New York City on June 23.

In her first major red carpet appearance in nine months, Jennifer Aniston, 45, looked better than ever! Maybe her secret to flawless, glowing skin is a good moisturizer! Luckily, we know what product she loves! Get her beauty look below!

Jennifer looked amazing standing by her fiance Justin Theroux. Her gorgeous blue eyes were lined in black, even on the bottom. Her cheeks were flushed in pink and she wore a shiny gloss on her lips.

Her skin looks seriously amazing. Jennifer is the spokesperson for Aveeno, so try out their Aveeno Positively Radiant Daily Moisturizer Broad Spectrum SPF 15 to get her look.

It helps improve tone, texture, dullness, blotchiness and lighten brown spots. Plus, the fact that it has an SPF built-in is a huge plus.

Jen's makeup was consistent with her usual look, but that isn't necessarily a bad thing. She knows what works for her!

Jennifer co-owns the company Living Proof. They have a bunch of new products for summer, including Living Proof Style Lab Prime Style Extender Spray.

We love this spray because it keeps your hair looking better, longer, as it repels dirt and oil. It detangles, smooths and perfects your locks. It's especially great for fine hair, and is safe for color-treated hair.

It's a weightless shield for your strands - perfect for summer!
