When she’s not filming her latest projects (like the sequel to Frozen!), Kristen Bell‘s most likely spending time with her two adorable children, helping husband Dax Shepard prep for a nude scene or working with Neutrogena as its brand ambassador. And with such a busy schedule, there’s not much time for the actress to relax and unwind — or wash her face each night. Lucky for her, she lives in a state that’s requiring residents to save water, which is great timing, as the star has partnered with Neutrogena Naturals to stop washing her face for seven days to bring attention to water conservation efforts.

The 34-year-old actress plans to use Neutrogena Naturals Makeup Remover Cleansing Towelettes for a week in order to help promote water conservation across the country, as part of The Nature Conservancy and Neutrogena’s new campaign, Wipe For Water.

“It’s a fun way to engage people, but The Nature Conservancy does really great work protecting ecologically important land, and [its] main focus is water and they release amazing stats,” she told PEOPLE. “I think people inadvertently consider water a never-ending resource, and the goal behind the campaign is just to enlighten people that hopefully — not anytime soon — but one day, we will have to start thinking about our water conservation, because it’s not an endless resource.”

Not to mention, Bell is glad to have one less step in her nighttime routine. “It’s a nice, lazy challenge, which I always enjoy, since the lazy challenges always tend to be easier,” she said.

She also enjoys keeping things low-maintenance when it comes to her hair, she said — and that includes her new bangs. “I had not had bangs for so long up until this year that I was craving a change … I cut them very long in an attempt to be a little bit more of a French fringe,” she told PEOPLE. “I enjoy that I can either push them to the side, pull them back or wear them down. So, I find them quite versatile right now, and I think bangs bring out a lot of youth, so climbing into my mid-30s, I really enjoy them.”

And though she’s constantly picking up beauty tips and tricks from her job, Bell’s sweetest beauty advice came from her husband, who told her to “stop wearing makeup, which is obviously very flattering!” she said. “I think he prefers me makeup-free.” Bell has even picked up a beauty tip (or two) from kids. “Not specifically [from my daughters], but I think what I’ve learned about beauty from children is number one, you’re always more beautiful when you’re laughing, and number two, a little bit of sunscreen can go a long way,” she said. “Your skin will simply look more youthful if you commit to wearing sunscreen and protecting yourself from UV rays.”

That explains why the star feels most comfortable in her own skin when she’s with her family. “I honestly feel most beautiful when I’m in a snuggle pile with them, and also when there’s no mirrors around,” she told PEOPLE. “Because I think it’s such a trap to think that beauty is all visual, and the more you focus on it being a feeling, the happier you’ll become. I truly believe that.”

Still, it’s fun to get dolled up for date night, just for a change of pace. “[I] usually [go with] a bold lip because I so rarely do that on the day-to-day, and it makes me feel very dressed up,” she said. “And as a mother of two young children, it’s a quick way to feel jazzy. I would love to say I did a gorgeous smoky eye, but I just don’t have the time. And I think that makeup is especially about balance, and I find that all I have to do is a swipe of mascara if I do a bold lip and it tends to be a quicker makeup process.”

And she treats herself to a beauty splurge whenever she has an extra minute. “If I have the time, I get a pedicure,” she said. “I usually stick in the red families; I like to stay bold for my feet. I think feet are not innately gorgeous, so they deserve a lot of pizzazz. [That’s why] I usually stick with a pretty bright red.”
