It's been a minute since Laguna Beach, but damn, Kristin Cavallari still looks good.

If anything, the 29-year-old former reality star looks better than ever. What's her secret? Sleep...and a pretty fancy face cream. At the relaunch of her Emerald Duv jewelry line, the mother of three shared her beauty staples and the surprising product she thinks is totally overrated (as well as advice for Kendall and Kylie Jenner).

Keep reading for her no-fuss, simple beauty tips as well the as product she's obsessing over.

What's your everyday makeup look?

Very simple.

What is your signature lip color?

Nude.

Bronzer or blush?

Bronzer.

What is your best non-product related beauty tip?

Sounds stupid to say, but drink a lot of water and make sure to take your makeup off at night. If I don't take off my makeup at night, my skin feels so clogged and disgusting. For me personally, that's huge.

Any current product obsessions?

Sisley Paris Black Rose Cream Mask—it gives you a youthful glow. Today, someone asked me if I got Botox...clearly it works. It fills in all your lines; it's really cool.

What product do you think is overrated/underrated?

I hate lip liner...totally overrated and I never use it. [For] underrated...I'd say brow pencil.

What makeup do you wear to the gym, if any?

Mascara.

What's your signature scent?

Michael by Michael Kors—I've been wearing it since I was 16.
