The properties of Centella asiatica for the skin?

Originating from Asia and Oceania, the Centella asiatica is a creeping, semi-aquatic herbaceous plant from the Apiaceae family. It primarily grows in the marshy areas of tropical or subtropical countries. Today, it can be found in several Asian countries such as India and China, as well as in Africa, mainly in Madagascar and South Africa.

Also known as tiger grass, the medicinal properties of this plant have been recognised for over 2,000 years. Asian populations used it in poultices to heal wounds and, more specifically, the skin manifestations of leprosy.

In cosmetics, the use of this plant in the form of powder or vegetable oil is relatively recent, beginning in the early 70s. Theextract of Centella asiatica is a rich source of natural bioactive substances : saponins, triterpenoids, flavonoids, phenolic acids, triterpenic steroids, amino acids, sugars... Today, it is possible to find this plant-based active ingredient in certain treatments intended for dull skin or in prevention of skin ageing, such as serums and creams.

It also formulates healing and restorative treatments to reduce the appearance of skin marks and/or stretch marks. Finally, it is found in eye contour creams, to lessen the appearance of dark circles and bags.

The phenolic compounds found in the leaves, roots, and petioles give the Centella asiatica powerful antioxidant properties that protect the skin from free radicals. These are generated by several factors such as UVA rays, pollution, cigarette smoke, excessive alcohol consumption, stress... These are molecules that are missing an electron. Highly reactive due to their instability, free radicals tend to react with the body's healthy molecules, damaging cells and tissues.

This process, known as "oxidative stress", accelerates skin ageing and therefore the appearance of wrinkles and/or pigmentation spots. The phenolic compounds present in Centella asiatica neutralise the action of free radicals by donating an electron to make these molecules stable and less reactive. Thus, this plant-based active ingredient delays skin ageing and protects the skin from external aggressions.
