Descriptif
One of the main biologically active components of the famous medicinal plant, Centella Asiatica, aka Gotu Kola. It has well established wound healing, skin-soothing and antioxidant activities.
There is also a study by La Roche Posay (belongs to L'Oreal) that examined the anti-aging effects of 5% Vitamin C combined with 0.1% Madecassoside. They mention that " Madecassoside is known to induce collagen expression and ⁄ or to modulate inflammatory mediators thus might prevent and correct some signs of aging." The surprisingly long, 6-month study observed "significant improvement of the clinical score for deep and superficial wrinkles, suppleness, firmness, roughness,andskin hydration", but Vitamin C in itself is already an anti-aging superstar, so it is hard to know how much Madecassoside did.
Another promising property of Madecassoside is that it seems to inhibit UV-induced melanin synthesis (test formula with 0.05% MA, used twice a day on 23 volunteers for 8 weeks), making it a great active for hyperpigmentation-prone skin.
If that would not be enough, the French manufacturer (Seppic) also has encouraging in-vivo studies on the molecule. Used at 0.2%, Madecassoside reduces redness and peeling in skin with light atopic dermatitis as well as itching in psoriasis-prone skin.
