Neutrogena Spokeswoman Kristen Bell Spills Her DIY At-Home Beauty Secrets

Forgetting Sarah Marshall actress Kristen Bell has always believed in going green.

The Neutrogena spokeswoman is now sharing her at-home beauty tips and do-it-yourself ways to keep your skin young and healthy without any added chemicals or harmful products.

The 34-year-old Veronica Mars star has been the spokeswoman for Neutrogena's Naturals line since 2011, and she has the skin to prove it.

"She's got an all-American look that is very relatable for a lot of women. She is a great fit for the brand," a source exclusively told E! Online when the actress landed the campaign in 2011.

Bell's eco-friendly upbringing has made it easy to think green in all aspects of her life, including skin protection.

"I think I grew up being taught a sense of responsibility, and that translated into blanketing the world around me, where it was my love for animals or my personal challenge to myself not to be wasteful," the actress told Us Weekly.

That being said, the Frozen actress — who is expecting her second child with husband Dax Shepard — loves using her own homemade beauty products to keep her healthy and youthful.

"I'll rub raw coconut oil on my tummy and then it's moisturizing and you smell like a Mai Tai, which is really lovely! I also love making little scrubs to keep in the shower. I'll mix brown sugar, honey and a little bit of olive oil and scrub my body with it," the When in Rome star said.

Now that fall has come, Bell has advice for women on how to keep their skin fresh and flawless in harsh conditions.

"Going into fall, I have drier skin because I wear so much makeup. When I use a cleanser, I need it to be a little bit creamier, and there's a purifying cream cleanser now and I'm excited about that," Bell revealed to the publication.

"I always wash my face before I go to bed with the Naturals cleanser," she explained about her most important bedtime beauty tip. "Consistency and simplicity is what my skin really, really responds to."
