mellow NOIR

mellow NOIR is an active-ingredient-driven cosmetics brand whose core ingredient comes from something that is a by-product of the coffee industry: used coffee grounds. Founder Julian Köster, a scientist and engineer, extracts coffee oil from them – an antioxidant active ingredient that supports skin regeneration and collagen production.

The idea grew out of a simple observation: coffee is shipped halfway around the world and afterwards thrown away almost completely. Julian first developed the extraction process in the garage at home. Almost two years and fourteen development samples later, the first product was there: the Facial Moisturiser. After starting with its broadcast on the founder show “Die Höhle der Löwen” in 2022, mellow NOIR is by now an established brand with more than 15 problem-solving products for a complete routine and is also listed in offline retail.

In June 2026, Good Brands AG acquired 26.14% of Truly Natural Cosmetics GmbH within an SPV together with several co-investors; the effective stake held by Good Brands amounts to 1.92%.
