Why vitamin C is notorious for skin care instability
“L-ascorbic acid is very unstable and breaks down to inactive dehydroascorbic acid when ionized,” explains cosmetic chemist Michelle Wong, founder of Lab Muffin Beauty Science. “This phenomenon occurs faster at higher pH, in more alkaline water, and when exposed to light and oxygen. It is also called oxidation because the decomposition reaction usually involves oxygen. This means that the effects of vitamin C decrease over time, and how quickly this happens varies by formula. When L-ascorbic acid breaks down, it turns yellow, orange, or brown. Therefore, it usually contains vitamin C. You can visually see how active it is.”
