Can red snow smooth out wrinkles? Discover the remarkable properties of snow alga
For years, scientists have been trying to outdo each other in finding a natural, non-invasive ways to smooth out wrinkles and delay skin ageing processes. One of the latest discoveries in this field is snow alga, an ingredient of PERLE BLEUE Visage Care Moisturise products. What are its beneficial effects?
Snow alga – also known as Chlamydomonas nivalis – owes these remarkable, promising properties to the harsh environment in which it grows. And, interestingly, it doesn’t grow in the sea, but in the frosty climate of the Arctic, Antarctica, the Himalayas and the Rocky Mountains, among snow crystals and in a layer of water on its surface. Although it is usually green, in warmer periods – under the influence of increased UV radiation – snow alga secretes a red pigment called astaxanthin. It is thanks to it that the snow takes on distinctive, red and pink colour.
Snow alga and the youth gene
To better understand where the phenomenon of action of Chlamydomonas nivalis lies, you need to take a closer look at DNA. In 1997, scientists discovered the Klotho ‘youth gene’, named in honour of the Greek goddess, which used to spin the thread of human life. Studies on mice have shown that when this gene ceases to work properly or is destroyed, this leads to accelerated ageing and premature death of the body. In addition, the highest levels of Klotho were observed in young mice.
The Klotho gene works closely with a protein called Foxo, located in the cytoplasm of your cells and is responsible for detoxification and DNA repair. However, this protein is inactive until nutrient deficiency occurs. Due to the fact that as a result of a shortage of calories, cells are exposed to damage, the active form of Foxo penetrates into cell nucleus and stimulates the defence mechanism of the cells, hampering their detoxification and anti-ageing activity. Klotho is one of the factors which have direct impact on the activeness of Foxo.
So, in order to prevent ageing of the skin, we need to find a substance which mimics the biochemical effect of calorie deficit and, just like Klotho, can support the activation of cell defence systems. And snow alga exhibits such properties.
An antidote against skin ageing?
Under the influence of raw climate, Chlamydomonas nivalis has developed an ability to produce secondary metabolites, including antioxidants, biopolymers, amino acids, polyphenols, compounds protecting the organism against stress or pigments (e.g. astaxanthin we have already mentioned).
Active ingredients of snow alga not only stimulate the Klotho gene, contained in our cells, increasing its expression even in older organisms, and thus strengthening the defence mechanisms of cells and DNA repair. They also reduce water loss through the skin and stimulate the production of two types of collagen, which is a protein responsible for its elasticity.
And although the mechanisms of action of the ‘youth gene’ are not yet 100% known, we already know that the use of this inconspicuous mountain alga, Chlamydomonas nivalis, can effectively influence them. It turns out that snow alga not only delays, but also reverses the effects of skin ageing.
