L-ascorbic acid requires a pH below 3.5 to penetrate skin effectively.
Pure L-ascorbic acid only penetrates skin reliably at a pH below about 3.5. This formula lists a strong alkaline pH adjuster high in the ingredient list, which suggests the finished pH may sit above that threshold. If so, the vitamin C is likely to be less effective than the concentration implies. Brands rarely publish finished pH, so this is an inference from the formulation, not a measurement.
