What is the Difference Between Vitamin C and Ester C?

The main difference between Vitamin C and Ester C lies in their stability, solubility, and acidity. Here are the key differences:

1. Stability: Regular Vitamin C, also known as ascorbic acid, is highly unstable and can quickly lose its potency when exposed to air, light, and heat. On the other hand, Ester C, which is a form of Vitamin C, is more stable and less prone to oxidation.
2. Solubility: Regular Vitamin C is water-soluble, while Ester C is oil-soluble. This difference in solubility makes Ester C easier for the skin to absorb and utilize.
3. Acidity: Regular Vitamin C is acidic, which can cause stomach irritation in some people. Ester C, also known as Ascorbyl Palmitate, is less acidic, making it gentler on the skin and less likely to cause irritation.
4. Skin Penetration: Ester C has been shown to penetrate the skin more effectively than regular Vitamin C, allowing it to provide more significant benefits.

In summary, Ester C is a more stable, less acidic, and more easily absorbed form of Vitamin C, making it a better choice for skincare products and those with sensitive skin. However, there is no evidence of a significant difference in the absorption of these forms of Vitamin C when ingested.

Please note that ascorbyl palmitate, also known as Vitamin C Ester, is a different compound from Ester-C and should not be confused with it.
