Understanding Vitamin C
Vitamin C is an umbrella term for several molecules with different properties. L-ascorbic acid is the most studied form but also the most reactive. Derivatives like sodium ascorbyl phosphate and tetrahexyldecyl ascorbate offer gentler profiles, often at the cost of potency. Pair vitamin C with sunscreen each morning to multiply environmental defense.
