What is the percentage of Vitamin C?Updated a month ago

HydraBright contains 10% 3-O Ethyl Ascorbic Acid, a derivative of pure Vitamin C, a stable, water- and oil-soluble derivative that combines stability and effectiveness in one. Where you may see other formulas with slightly higher percentages, it's important to note that higher percentages are not always the most effective as that can often be in a diluted form.
