What is it

What is Vitamin C?

Vitamin C is one of dermatology's most proven brightening and antioxidant ingredients - but its effectiveness depends heavily on formulation. L-ascorbic acid is the most potent form but can oxidizes quickly. To address this, advanced Vitamin C formulas combine multiple derivatives: L-Ascorbic Acid - The purest and most potent form, most extensively studied. Tetrahexyldecyl Ascorbate - Fat-soluble, highly stable, well-tolerated by sensitive skin. 3-Glyceryl Ascorbate - Newer-generation, converts to active Vitamin C once absorbed. Magnesium Ascorbyl Phosphate - Water-soluble, pH-stable, ideal for sensitive skin.
