Meet our founder

Katelyn Rousselle

Katelyn has over 20 years of hands-on experience treating clients’ skin in dramatically different climates. From dry heat and high-altitude chill to coastal humidity and urban pollution, she’s become an expert in how environment shapes skin. She’s built a skincare line for women navigating everyday stressors that show up on our faces first.

Her own skin story is just as real: breakouts in her teens and twenties, sensitivity and dryness after pregnancy, flare-ups from frequent moves and climate changes. As a mom of two, she’s no stranger to sleep deprivation, hormonal shifts, and the invisible toll that motherhood takes on skin. Like many women, she was frustrated by the endless trial-and-error of overcomplicated routines that didn’t deliver. She wanted something better, something that worked with the skin, not against it.

That vision led to Atmosphera: female-founded, climate-adaptive skincare. Designed to simplify routines and support the skin’s natural resilience, it’s skincare for real life — and for women who do it all.
