Great recommend
usually go for serums with pure Ascorbic Acid in them. Those are mostly water-based and oxidise very, very quickly. This serum from AoS is different: first, it has a waterless formula, and then it uses a Vitamin C derivative. This has positive and negative results: it won’t spoil quickly, it won’t be as potentially sensitizing as pure Vitamin C, but then, the texture will be dramatically different to a water-based serum – and, then, we deal with a derivative.
