Usage, safety and formulation details
Mechanism of action
Derivatives differ in water or oil affinity, conversion to ascorbic acid and intrinsic activity. Skin conversion and useful delivery cannot be assumed from the vitamin C name.
Sources: 1, 2Potential adverse effects
Irritation or contact allergy may occur; stop a product that causes a persistent or marked reaction.
Sources: 1, 2Formulation considerations
Identify the actual derivative, concentration, stability, pH range and supporting studies. Do not translate percentages or acidity requirements directly from pure ascorbic acid.
