Usually I speak of “pure” ingredients like Centella asiatica (gotu kola), well known, and whose benefits to our skin are indisputable. But every time there is a tendency to bet on natural cosmetics (whatever that is), and therefore considered it important to know some extracts that really make a difference.
The Asian Centella is a plant that is very widespread in South America. Africa and especially in Asia, where it is widely used in medicinal preparations. In this case only the stems and leaves of Centella asiatica (gotu kola) are used, where the compounds of interest. These include asiaticoside, mandecassoside, that in our skin are metabolized Asian acid and mandecassic acid and also some flavonoids.
In cosmetics can be found both in the extract of the plant in the form of isolated active molecules, in higher concentrations, allowing a more effective action.
Re-epithelialization with Centella asiatica (gotu kola)
Centella asiatica (gotu kola) extract showed accelerating the closing of open wounds, promoting a greater thickness of the skin on the treated skin. It is believed that surrounding wound fibroblasts are stimulated to migrate to the injured areas, and / or that the active compounds of this plant stimulate the production of growth factors essential for skin healing.
In addition to compounds that contain antioxidant action, this extract has the advantage of stimulating the natural antioxidant capacity of the skin. This latter characteristic is especially interesting, and differs from Centella asiatica (gotu kola) compounds of other antioxidants.
Stimulates the production and creation of collagen and other components of the dermis
The Centella asiatica (gotu kola), but also the mandecassósido demonstrated that it stimulates the synthesis of collagen and in the human fibroblasts, and to improve the formation and the coherent network of this fiber. This last aspect is very important for the resistance of the dermis.
In addition, it was also found that the active compounds of this extract can stimulate the synthesis of fibronectin, proteoglycans, and glycosaminoglycans, but also as hyaluronic acid, which are important for skin’s strength, volume and hydration.
These components of the dermis and join the interlocking three-dimensional network.
Therefore, the fact that the Centella asiatica (gotu kola) simultaneously capable of stimulating the production of all this they especially interesting extract does.
Stimulates the growth of new blood vessels
When applied to open wounds, this extract was found to enhance the proliferation of new blood vessels that are important for transporting oxygen and nutrients to injured skin.
Also used in cosmetics
Healing of wounds and burns
Centella asiatica (gotu kola) extract and its compounds isolated are already widely used in medical preparations and cosmetics in the treatment of wounds, as it improves the blood supply to the affected area, stimulate the resumption of the antioxidant defenses of the skin; But above all because they stimulate the formation of new cells and improve the quality of collagen synthesis.
Several studies show that when treated with effective concentrations of active Centella asiatica (gotu kola), wounds heal faster and formed a new skin has better elasticity and firmness than was treated.
As the skin of the wound, also the skin being pulled abruptly may not be able to radiate synthesizing. Which necessary for such dermal fibers, forming splines. Therefore, Centella asiatica (gotu kola) extract is also made especially interesting in the prevention and treatment of the early stages of this problem.
By stimulating the synthesis of dermal components, Centella asiatica (gotu kola) can be used as a topical adjuvant treatment of cellulite. Improving strength and overall quality of the skin for long-term.
Protection from the sun
The direct antioxidant action of Asian Sparkling extract makes it interesting in sun protection. However, the fact of promoting the increase in the natural antioxidant defense ability of the skin gives an even more important role!
By improving the synthesis of collagen, glycosaminoglycans, but also the antioxidant capacity of the skin. Extract of Centella asiatica (gotu kola) becomes a particularly interesting extract to prevent and correct skin signs of aging.
However, they are not carried out in human studies comparing the efficacy of using this isolated extract. While each of the active compounds with “standard” other ingredients used in the treatment of skin aging. Nor is it expected that at some point this proves … But these things, you never know.
Therefore, in anti-aging products, Asian Centella should be seen only as an auxiliary statement.
