The effects of Centella Asiatica
The effects of Centella Asiatica are manifold. Firstly, it has positive effects on wound healing, as it has antioxidant, anti-inflammatory and regenerative properties. Therefore making it a very interesting ingredient in cosmetics industry. In traditional medicine, such as in Chinese medicine, the effects of Centella Asiatica have been used for centuries (Bradwejn et al, 2000). And there are already many proofs of its effectiveness in Western medicine. Triterpenes, an ingredient of Centella Asiatica has some unique impact on the skin (Hashim, 2011). This has emerged from research focusing on specifically the leaves of Centella asiatica.
Centella Asiatica Leaf extract
The leaves of Centella asiatica were analysed for their triterpene composition and their bioactivity such as collagen enhancement, antioxidant, anticellulite and UV protection. (Bradwejn et al, 2000). In addition, saponins is found in Centella asiatica leaves which is a subgroup of the triterpenes. In addition, further evaluations found that chemical composition consist of four triterpenes, which are the following:
- madecassic acid, and
- asiatic acid.
(Bradwejn et al, 2000).
Firstly, the leaf extract significantly stimulated collagen synthesis in comparison to vitamin C. Secondly, the lipolysis activity is better than that of caffeine. Thirdly, the extract also showed an inhibitory effect with regards to free radical scavenging activity. And finally, research studies outlined that the Centella Asiatica extract could be a potential natural protection against UVB damage and this activity is due to its triterpene component(s) (Chandrika et al, 2015).
What research confirmed

Thus, the correct dosage and high-quality is key to ensure the skin experience these positive effects. (Bylka et al, 2013) .
Research has confirmed the following so far
- The triterpene factors stimulate the synthesis of collagen and fibronectin in skin cells.
- Isolated asiacosides as well as madecassoids stimulate the collagen synthesis in skin cells.
- Extracts of Centella Asiatica have antibacterial and antioxidant properties.
- A combination of vitamin C and madecassoids achieves a reduction in wrinkles or an improved skin appearance in sun-aged skin.
