When and how often should Centella Asiatica be used?

Also known as tiger grass, the medicinal properties of this plant have been recognised for over 2,000 years. For instance, 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, dating back to the early 1970s. The extract of Centella asiatica is a rich source of natural bioactive substances: saponins, triterpenoids, flavonoids, phenolic acids, triterpenic steroids, amino acids, sugars... Two molecules in particular have been isolated and give it excellent wound healing properties : namely madecassoside and asiaticoside.

Firstly, this plant is highly effective in combating the onset of ageing signs. Indeed, due to its biochemical composition, it stimulates the synthesis of collagen, a vital protein for skin firmness which decreases with age. It is also renowned for its antioxidant action, attributed to the phenolic compounds found in its leaves, roots and petioles. It thus significantly limits the production of oxygenated chemical species such as free radicals. As a reminder, these unstable and highly reactive molecules damage a wide range of the body's healthy molecules (DNA, RNA, proteins...), accelerating its ageing process.

The Centella asiatica is also recognised for its restorative properties. Studies have demonstrated its benefits in reducing stretch marks as well as skin blemishes such as acne scars, also known as post-inflammatory hyperpigmentation.

Finally, it stimulates microcirculation of blood which strengthens the walls of the blood vessels, preventing the appearance of varicose veins on the body and dark circles under the eyes.
