                                Vitamin C is a notoriously unstable ingredient, with studies showing its degradation upon exposure to light and oxygen. This fragility raises a critical question for consumers: should vitamin C come in a dark bottle? The answer lies in understanding the science of oxidation and how packaging is a key defense against it.
