Katelyn Rousselle built a brand with decades of real world skin experience.

With over 20 years spent treating skin across dramatically different environments, from dry desert heat to coastal humidity and urban pollution, Katelyn has worked hands on with thousands of faces and skin conditions. Through that work, one truth became impossible to ignore. Skin does not exist in a vacuum. It responds, adapts, struggles, and changes based on the environment around it.

Atmosphera was born from a refusal to accept the limitations of traditional skincare thinking. Katelyn saw firsthand how often products ignored how skin actually behaves in real life. While much of the industry focused on rigid skin types, trend driven ingredients, and increasingly complicated routines, clients remained frustrated and inconsistent results persisted.

Her perspective was different. Skin type was not the real problem. The environment was.

Weather, climate, stress, pollution, and lifestyle all place daily demands on the skin barrier. When those factors shift, skin shifts with them. Atmosphera was created using this lens, designing products that support skin through change rather than fighting it.

As a founder, mother, and long time practitioner, Katelyn believes skincare should be intelligent, adaptable, and uncomplicated. Atmosphera’s routines are intentionally streamlined, multifunctional, and results driven, created to strengthen skin resilience rather than overwhelm it.

Today, Katelyn remains deeply involved in product development and brand vision, continuing to work with skin and staying connected to the realities her customers face every day. Atmosphera is not about chasing trends. It is about respecting how skin truly works, and giving it what it needs to thrive wherever life takes you.
