Start up beauté innovante 2022



Mastel was imagined in San Francisco in 2020, and was born from the desire to create a cosmetics company that respects the skin and the environment while breaking down the rules of beauty.

An adventure that began at the University of Berkeley Botanical Garden 🌱.

It was at the sight of a very beautiful Ginkgo biloba that the idea of ​​a range of cosmetics centered on the properties of this tree was born: an incredible longevity ensured by numerous antioxidants.
