We use Sodium Ascorbyl Phosphate as our core vitamin C because it is GENTLE and STABLE (i.e. the good stuff reaches your skin). Sodium Ascorbyl Phosphate (SAP) is the holy grail as it offers similar perks as L-ascorbic acid, mainly antioxidants, and collagen-boosting and pigment-evening properties. Research has also shown it can regulate sebum production and acne inflammation, sebum oxidation (which is the early stages of acne development) so it’s essentially stopping acne production process before its begun. Boom. We strategically combine Sodium Ascorbyl Phosphate with a second complimentary form of vitamin C, called Ascorbyl Tetraisopalmitate. Another super-stable form of Vitamin C, studies demonstrate that Ascorbyl Tetraisopalmitate will remain in the s­­­kin cells forty to eighty times longer than L-ascorbic Acid and will have as much as four times the effect[1]. Additionally, studies have shown faster absorption into the skin than other forms of vitamin C owing to its lipid solubility[2]. [1]  Stamford, n. (2012).
