Our team of dermatologists embarked on a three-week journey to evaluate ten top-rated vitamin C serums available in the market today. The focus was primarily on products containing a stable form of vitamin C, such as L-ascorbic acid, known for its potent antioxidant properties. A broad spectrum of products was tested, with a focus on items under $50. The results served as a guide for identifying the best vitamin C serums that could potentially enhance your skincare routine.
