Why do alpine plants fascinate researchers so much?
Updated October 18, 2026
Alpine plants grow in one of the harshest environments in Europe: more intense UV radiation at high altitudes, cold, wind, and drought. To survive, some species, such as Edelweiss, produce antioxidant molecules like leontopodic acid, which are studied by Swiss research institutions (Agroscope, Mediplant). This work inspires the Belle Luce approach: observe, understand, then formulate.
The Alps: an open-air natural laboratory
When one thinks of the Swiss Alps, one imagines snow-capped peaks, glaciers, and high-altitude pastures.
For botanists, biologists, and researchers, however, the Alps represent much more than just scenery.
They constitute a natural laboratory, where each plant has been subjected, for thousands of years, to some of the most demanding conditions in Europe.
As altitude increases, constraints intensify. According to the World Health Organization, ultraviolet radiation increases by approximately 10% every 1000 meters. The temperature fluctuations between day and night become more pronounced, wind is omnipresent, water becomes scarcer, and the growing season is reduced to just a few months. In this environment, only species that have developed effective adaptation mechanisms survive.
Each alpine plant thus tells a story of adaptation.
A story written by nature over millennia.
Observe before formulating
At Belle Luce, our approach has never been to seek out the latest trendy ingredient.
It always begins with a much simpler question:
How does living matter solve its own challenges?
Our brand was born in Valais, at the foot of these mountains. It is by observing the plants that thrive in these extreme environments that we choose the active ingredients for our formulas.
Why do certain species resist where others disappear?
How do they protect their cells against the permanent aggressions of their environment?
These are also the questions currently being asked by many researchers in botany, phytochemistry, and plant biology.
Three adaptation strategies
Unlike animals, plants cannot flee the cold, seek shade, or take shelter from the wind.
They must adapt on the spot.
Some form compact cushions close to the ground to retain heat and escape the wind.
Others cover themselves with fine hairs that limit water loss and filter part of the radiation. This is the case with Edelweiss, whose woolly appearance is its signature.
Finally, some produce molecules capable of protecting their cells against the effects of UV rays, cold, and oxidative stress: phenolic compounds, such as the leontopodic acid found in Edelweiss.
It is this chemistry of protection that interests researchers: it allows for a better understanding of how living things defend themselves against oxidative stress.
When science turns its attention to alpine plants
For about twenty years, several Swiss and European research teams have dedicated their work to alpine plants.
In Valais in particular, Agroscope, the Swiss federal center for agricultural research, and Mediplant, specialized in medicinal and aromatic plants, have contributed to developing knowledge about Edelweiss and to establishing crops intended to preserve the wild species while enabling its scientific study.
This research has made it possible to better understand the chemical composition of Edelweiss, to identify its main phenolic compounds, and to select varieties adapted to organic mountain farming, such as the Helvetia variety.

Our skin faces comparable aggressions
While alpine plants must resist UV, cold, wind, or environmental stress, our skin is also confronted daily with numerous aggressions.
Solar radiation.
Pollution.
Chronic stress.
Lack of sleep.
Tobacco.
All these factors promote the production of free radicals, unstable molecules that contribute to the phenomenon of oxidative stress. When their production exceeds the organism's natural defense capacities, they can contribute to premature cellular aging and the alteration of certain skin constituents.
It is this similarity between the challenges encountered by alpine plants and those to which our skin is exposed that currently interests cosmetic research.
A philosophy born of the mountains
At Belle Luce, we believe that the best innovation does not consist of reinventing nature.
It consists first of observing it.
Alpine plants have developed their survival strategies over thousands of years.
Scientific research helps us today to understand these mechanisms and to identify certain molecules naturally produced by these plants.
Our role is then to select active ingredients with documented properties, to collaborate with Swiss scientific partners, and to integrate them into formulas developed with special attention given to sensitive skin.
This approach forms the very foundation of Belle Luce: observe, understand, then formulate.
Frequently Asked Questions
Why do alpine plants resist extreme conditions?
They combine several strategies: a compact shape close to the ground to retain heat, dense hairiness that limits water loss and filters part of the UV rays, and the production of protective molecules, notably phenolic compounds with antioxidant activity.
Why is altitude so demanding for plants?
UV radiation increases by approximately 10% every 1000 meters. Added to this are sharp temperature variations between day and night, constant wind, scarcer water, and a growing season of only a few months.
What is leontopodic acid?
It is a phenolic compound identified in Edelweiss and described in 2005 by Stefan Schwaiger's team. In vitro studies have highlighted its antioxidant activity. It is detailed in our article Edelweiss in cosmetics.
Is the Edelweiss used in cosmetics picked in the wild?
No. Wild Edelweiss is protected in Switzerland. The Edelweiss intended for cosmetics comes from cultivation, thanks to varieties selected by Swiss research, such as the Helvetia variety. The extract used by Belle Luce is of Valais origin.
What is the link between alpine plants and skincare?
Our skin also suffers from oxidative stress, linked in particular to the sun, pollution, and lack of sleep. The antioxidant molecules that alpine plants produce to defend themselves are therefore of interest to cosmetic research, to help the skin cope with these daily aggressions.
Are Belle Luce Edelweiss skincare products suitable for sensitive skin?
Yes. They are formulated with special attention paid to sensitive skin. To choose your skincare products wisely, consult our guide Reactive skin: how to choose your cosmetics?
