Over 50% of topical vitamin C products containing L-ascorbic acid can lose their potency and oxidize quickly when exposed to light or air. This instability led to the development of enhanced vitamin C derivatives like e-ascorbic acid, which offer improved stability and absorption for more consistent results.

Despite its potent benefits, L-ascorbic acid, the purest form of vitamin C, is notoriously unstable, degrading rapidly when exposed to heat, light, and air. Determining what is the most stable and effective form of vitamin C depends on whether you are seeking oral supplementation or a topical skincare treatment.

A statistic shows that pure L-ascorbic acid can degrade significantly within 12 months, losing its potency when exposed to air and light. Finding the most shelf stable vitamin C derivative is crucial to keep your supplements and skincare effective.
