A common type of vitamin C, it is currently considered to be a powerful antioxidant and anti-inflammatory substance. It inhibits the activity of tyrosine enzymes, resists free radicals, and helps the synthesis of collagen. In addition, the pH value of L-C skin care products should be low enough so that L-C can remain stable, but it may also cause skin irritation. It is acidic, has low stability and is difficult to store, and is more irritating. It is sensitive to light and has low stability. It is usually not used directly, but its derivatives are used.
