When and how often should you use Centella Asiatica?

Also known as tiger grass, the medicinal properties of this plant have been recognized 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, beginning in 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 : the madecassoside and the asiaticoside.

Firstly, this plant effectively combats the appearance of aging signs. Indeed, thanks to its biochemical composition, it stimulates the synthesis of collagen, a protein essential for skin firmness, the content of which decreases with age. It is also renowned for its antioxidant action, which it owes to the phenolic compounds present 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 aging.

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

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