Edelweiss Extract

Leontopodium alpinum grows at punishing altitudes where UV intensity and temperature swings would destroy most plant tissue. Its survival strategy is a dense cocktail of antioxidants — leontopodic acid (exclusive to this plant), chlorogenic acid, and luteolin — that modern cosmetic labs harvest via plant cell culture rather than wild collection. In vitro evidence is solid: leontopodic acid matches or exceeds vitamin C's free-radical scavenging in several assays. It's the defining botanical of Swiss/Austrian/German alpine skincare (Weleda, La Prairie, Susanne Kaufmann). Clinical data on humans is still modest, but the antioxidant pedigree is real.
