The COSRX Centella Blemish Cream is a skincare product containing Centella Asiatica extract as its key active ingredient. Centella Asiatica, also known as Gotu Kola, is a plant-based compound known for its anti-inflammatory and wound-healing properties. The primary active compounds in Centella Asiatica are triterpenoids, including asiaticoside, asiatic acid, and madecassic acid. These compounds have been found to stimulate collagen production, improve skin elasticity, and reduce inflammation. Asiaticoside, in particular, has been shown to enhance wound healing by increasing the levels of antioxidants and fibroblast activity in the skin. In addition to Centella Asiatica extract, the COSRX Centella Blemish Cream also contains other beneficial ingredients such as zinc oxide and cetearyl alcohol. Zinc oxide is a mineral compound that provides UV protection and helps to soothe irritated skin. Cetearyl alcohol is a fatty alcohol that acts as an emollient, making the cream more effective at moisturizing the skin. The cream has a slightly acidic pH of around 5.5, which is close to the skin's natural pH level. This helps to maintain the skin barrier function and minimize irritation. The cream has a medium viscosity, allowing it to be easily spread on the skin and absorbed quickly without leaving a heavy residue.
