What is the difference between Ascorbyl Tetraisopalmitate and L-Ascorbic Acid?
Ascorbyl Tetraisopalmitate is an oil-soluble, stable derivative of Vitamin C, while L-Ascorbic Acid is the pure, water-soluble form. Ascorbyl Tetraisopalmiate is generally less irritating and penetrates the skin more effectively, converting to L-Ascorbic Acid once absorbed.
Is Ascorbyl Tetraisopalmitate suitable for sensitive skin?
Yes, Ascorbyl Tetraisopalmitate is often well-tolerated by sensitive skin types due to its gentle nature and stability, making it a good alternative to more potent forms of Vitamin C that can cause irritation.
