Welcome to Beauty Around the Clock, Marie Claire's weekly peek into the daily lives of the most influential women in their industries. How do these women get their day's work done?

In 2018, Randi Christiansen stepped down from her executive role at beauty powerhouse Estee Lauder Companies and teamed up with Nick Axelrod to launch Nécessaire (opens in new tab), a clean body and sex care line. The brand reimagines self-care with gender-neutral products and chic, minimalist packaging. Scroll through Instagram and you'll rarely find an influencer's vanity or bathtub without the brand's cult-favorite body lotion (opens in new tab), body serum (opens in new tab), or sex gel (opens in new tab). The idea behind Nécessaire is to create a sustainable personal care destination," Christiansen says. 'Body care tends to get put on the back burner because it's not something we think about first. We wanted to change that paradigm. We start where [other companies] end up." Here is a day in the life of the co-founder and CEO.

At 7 a.m. I splash water on my face, run down to make coffee, and wake up my three daughters. Then I run back down and give my husband a good morning kiss. My Bullmastiff usually joins me every step of the way.

Since I am a Scandinavian girl, my beauty ritual is simple: in the morning, I spend a maximum of five to ten minutes on my beauty routine. After rinsing my face with water, I mix a good serum and a good moisturizer in one step. Most days, I put on sunscreen and lipstick. These days I use Charlotte Tilbury's Bond Girl.

My hair is Nordic fine, so I clip it up.

I love to run. My favorite time to run is just as the sun is setting. For me, time spent in nature is always my favorite.

Baths are my dream. But the shower is my reality. I first put The Body Wash (open in new tab) in the water. Then I use The Body Serum (open in new tab) and The Body Lotion (open in new tab). For the face, I usually cleanse with Tatcha's Deep Cleanse (open in new tab) and then use Vintner's Daughter Botanical Serum (open in new tab). Finally, use Dr. Barbara Sturm's Face Cream Rich (open in new tab). Do not mix. Step by step. For hair, simply spray rose water.

11pm is optimal. Midnight is my reality.
