Firn: The Alpine biotech company reinventing skin regeneration

Alpine Glaciers: The Source of Cell Regeneration

It is there, where the cold is extreme and life seems to stand still, there in the heart of the Alpine peaks, that the power of cellular regeneration lies hidden… It is in this harsh environment that microorganisms and plant cells develop powerful and unique mechanisms of resilience and regeneration, preserved for millennia beneath the ice. A natural intelligence that raises the question: if these organisms are able to withstand UV rays, cold and extreme stress, don't they have a strength that our skin cells could exploit? It is precisely this question that gave rise to the skincare brand Firn. Working alongside Dr. Fred Zülli, a pioneering Swiss researcher in cell biology and particularly in stem cell research, Firn transforms this alpine inspiration into concrete technology to stimulate the skin’s natural regeneration.

STM30®, the biotech complex that works with the skin

Behind Firn’s formulas lies an exclusive and innovative complex: STM30® (Thirday Days Stem Cell Complex), developed in Switzerland by Dr. Fred Zülli exclusively for the skincare brand. It combines a high concentration of two biotechnology-derived active ingredients: stem cells from Alpine plants and microorganisms sourced from the thin layer found in glaciers, between the snow and the ice (known as firn in Germanic languages). The longevity and resilience of these two high-mountain ingredients are truly exceptional:

Stem cells from alpine plants accelerate and optimize the action of skin stem cells to boost cell regeneration.
Microorganisms found in glaciers stimulate the production of proteins that reduce oxidative stress and boost cellular energy (ATP) to revitalize the natural production of collagen and elastin.

Where other products mask the signs of fatigue, Firn awakens the intrinsic strength of cells for plumper, more radiant skin that is resistant to daily stress, day after day.

It all began with Dr. Fred Zülli, a pioneer in scientific research

Dr. Fred Zülli, a Swiss researcher renowned for his work on stem cells and tissue regeneration, transformed this Alpine inspiration into a cosmetic innovation based on the principles of biotechnology. Fascinated by the ability of microorganisms and plant cells to survive for millennia beneath the ice of the Alps, he devised a way to transfer this energy to human skin. During an expedition to the Alps about ten years ago, he collected a sample of plant microorganisms, which he cultivated in vitro in the laboratory until he obtained the extract that forms the STM30® Alpine Biotechnology Complex, found in all Firn skincare formulas.

Scientifically proven benefits

And the STM30® complex isn’t just an Alpine innovation—it’s also backed by science. Eight clinical studies have measured its effects, confirming that the combination of Alpine stem cells and glacial microorganisms truly stimulates skin regeneration. The results speak for themselves: reduced wrinkles, diminished dark circles, enhanced hydration, and smoother, plumper skin texture. Dr. Zülli explains: "When exposed to alpine stem cells, skin stem cells increase their production of new cells by 75%." And the results of in vitro studies conducted by Firn show a reduction of 3.5 years in the skin’s biological age. A biotechnological breakthrough that delivers visible, long-lasting results: day after day, the skin regains energy, radiance, and resilience against daily stress.

A powerful, simple, and accessible routine

Convinced that cellular regeneration knows no age or skin type, the trio of entrepreneurs—Sacha Bostoni (former founder of Jimmy Fairly), Clémence de Stabenrath, and Raphaële Four—have developed a high-performance cosmetics brand that embodies the principles of scientific luxury in an accessible form.

And the formula works… Among the cult-favorite products you’ll find on our shelves is the Multi-Corrective Regenerating Cream, with its unique dome-shaped container, had no trouble quickly rising to the ranks of iconic skincare products. This is thanks to its formula enriched with STM30® and supplemented with encapsulated collagen peptides and Vitamin E, to help the skin regain elasticity, firmness, and radiance.

Other products in the Firn routine include:

Regenerating Serums with high-tech formulas to target dark spots, blemishes, wrinkles and fine lines, and loss of firmness or radiance.
A Targeted Filling Treatment for the Eye Area to directly target crow’s feet, and a Targeted Filling Treatment for the lip contour to effectively target nasolabial folds.
Rejuvenating Drops that blend makeup and skincare to instantly revitalize your complexion.
