When and how often should you use Centella Asiatica?

The centella asiatica is a creeping, semi-aquatic herbaceous plant native to Asia and Oceania. It is recognized for promoting the repair and regeneration of damaged skin tissues.

What is 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.

The cosmetic virtues of Centella asiatica.

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.

At what time of the day should a Centella asiatica skincare product be used? And at what frequency of application?

In order to fade various types of skin marks and/or prevent the appearance of wrinkles, different formulations contain extract of Centella asiatica and are now distributed in the cosmetic market. This plant-based active ingredient can thus be found in creams, lotions, toners, aqueous serums, or even night masks. It is also found in certain hair products to strengthen the hair and protect it from drying out.

Skincare with Centella asiatica can be safely used twice a day, daily. This active ingredient is not photosensitizing (it does not increase skin sensitivity to the sun's UV rays), so you can apply your product morning and evening. However, make sure to protect your skin every morning with a broad-spectrum sunscreen.

Even though Centella asiatica is an ingredient generally well tolerated by all skin types, it is still possible to develop an allergic reaction in the form of contact dermatitis. To avoid this, a preliminary application of the product in question on the inside of the elbow is recommended. If redness appears, avoid using the skincare product.

Theanti-mark serum from Typology, based on PHA and Centella asiatica is used only in the evening as PHA is a photosensitizing substance. Highly concentrated, it is applied in a localized manner, on the skin mark to be faded. This serum is suitable for all skin types and particularly for skin prone to marks/scars related to acne.
