The founder

“I created Le Sérum because intimate skin deserves the same care, attention and innovation as the rest of our body. Eau de Nuit is here to help women feel informed, confident and cared for at every stage of life.”

I’m Kelly Strömmer, founder of Eau de Nuit. With a background in aerospace engineering and stem stell and bacteria research, I saw intimate care as an area ready for more thoughtful innovation.

As a woman, I became increasingly aware that intimate care had not received the same level of attention, research or product development as other areas of skincare. Most existing solutions were created to respond to individual concerns, rather than support intimate skin as part of an everyday care routine. I wanted to change that.

The intimate ecosystem is complex and sensitive, so I knew a meaningful solution would require expertise from several scientific fields. Over four years, I collaborated with specialists in the microbiome, plant stem cell research and cellular rejuvenation to develop our first product Le Sérum Régénérant Intime.

Its biomimetic formulation is designed to support, rebalance and regenerate intimate skin while working in harmony with the body. Le Sérum is the first step in our wider mission to establish a new category: regenerative intimate care.

Welcome to the world of Eau de Nuit, an intimate care for every day and every stage of life.
