Over 40% of American adults take a multivitamin, and many turn to 'Super C' products for an extra boost. The question is, does super C really work for immune support, skin health, and other popular claims? The answer depends heavily on the product and application.

According to dermatologists, a potent vitamin C serum can dramatically improve skin tone and texture, but its power is fleeting if exposed improperly. The simple answer to 'does vitamin C go bad when exposed to air?' is a definitive yes, due to a chemical reaction called oxidation.

While the Recommended Dietary Allowance of Vitamin C for adults is typically 75-90mg, topical applications can reach far higher concentrations, leading many to ask: 'Is 20% ascorbic acid too much?'. The answer depends heavily on your skin type, tolerance, and how you introduce this potent ingredient into your routine.

According to a study published in the Brazilian Journal of Pharmaceutical Sciences, 92% of vitamin C supplements showed significant losses in concentration after just 12 months of storage. This instability means understanding how long does vitamin C stay stable is crucial for ensuring you receive the full benefits of this vital nutrient.
