A recent arcticle in the Guardian UK discusses the threat to alpine plants as a result of melting glaciers. Here is a link to the article: Alpine plants face extinction as melting glaciers force them higher, warns study
DU NORD SKIN CARE products contain a number of ingredients derived from plants that have alpine and sub-alpine habitats. They are carefully sourced both for efficacy, sustainability, and eco-responsibility.
Extracts derived from the leaves of Rhododendron ferrugineum, alpine rose or alpenrose, and the leaves and flower petals of Leontopodium alpinum (edelweiss) are two important ingredients in DU NORD SKIN CARE. The plant sources in DU NORD SKIN CARE products are cultivated organically (edelweiss) or sustainably wildcrafted (alpine rose) in specially designated alpine plantations in Switzerland and are certified by ECOCERT/COSMOS. Both are key ingredients in PRAIRIE Serum and MOUNTAIN Gel Cream.
Ingredients are also derived from sub-alpine plants in DU NORD SKIN CARE, including Juniper communis, the hardy, common juniper we have here in Ketch Harbour, Nova Scotia. Juniper oil is used in TUNDRA Oil and FOREST Oil. It comes from Quebec, organically certified through USDA and the Quebec organization OCQV. An oil derived from Vaccinium myrtillus, bilberry (also known as European blueberry), is a key ingredient in BOREAL Emulsion, TUNDRA Oil and MOUNTAIN Gel Cream. The source for this cold-pressed oil are up-cycled bilberries from juice industry as part of a circular economy mode of production. It is certified by the Nordic Swan Ecolabel.
Edelweiss has a long history of traditional use as anti-inflammatory. In vivo studies with animal models have verified its anti-inflammatory action. Some edelweiss extracts have been found to protect against UVA/B radiation. The robust anti-oxidant activity of edelweiss protects cellular DNA from oxidative damage.
Two key phenolic acids that play a large role in this anti-oxidant effect are leontopodic acid and chlorogenic acid.
Some edelweiss extracts have also demonstrated significant anti-bacterial activity, and more recent study suggests that chlorogenic acid may be beneficial in the treatment of acne vulgaris. Edelweiss is used in DU NORD SKIN CARE products for its potential as a strong anti-oxidant/photo-protective ingredient, its anti-inflammatory properties (soothing, aid in alleviating visible manifestation of inflammation and edema) and for its antimicrobial action (and possible aid in reducing symptoms of acne vulgaris).
Alpine Rose may seem a more unusual plant for a skincare product. It is "moderately toxic” if ingested. That said, I think we’re safe. Neither PRAIRIE Serum nor MOUNTAIN Gel Cream ought to stimulate one’s appetite…. I have been able to find only a single ethnobotanical study that mentions a traditional use of Alpine Rose. It turns out that in the Lombardy region of the Northern Italy, in an alpine valley region that borders Switzerland, Alpine Rose was used as a treatment for small fractures.
An innovative company in Switzerland has studied Alpine Rose leaf extracts and developed an active ingredient that—according to their analyses— eliminates cells that become damaged and programmed to die (senescent cells)—cells which may trigger inflammation and structural changes in the extracellular matrix of the skin; reduce oxidative damage, especially resulting from UVA radiation; reduce visible signs of inflammation; and stimulate and rejuvenate deeper layers of skin and promote skin elasticity. Wow--a potent multifunctional active!
