  • Vitamin C is prone to oxidize, when that happens it turns into a brownish color and loses its efficacy. Buy a vitamin C serum that is almost colorless, or has light creamy color. Avoid buying ones that have an orange or brown color, because you will never realize when it oxidizes.

  • Vitamin C comes in different types of concentration, from less than 1% to more than 20%. If you are starting to use it choose a low concentration (5% or less) to check how your skin responds to it. After it is adapted you can try with a higher concentration.
  • You can also try with vitamin C derivates. The pure form of vitamin C is ascorbic acid, other forms are knowns as derivates and although they may not be as potent as the pure vitamin C, they are more gentle in the skin and less prone to oxidize. Some of the most famous vitamin C derivates are ascorbyl glucoside, ascorbyl palmitate, and magnesium ascorbyl phosphate. 
  •  The price of a product is not always an indication of quality. However, keep in mind that a good formulation and proper stability and bioavailability testing can be costly.

Those mechanisms result in a reduction of brown pigmentation. Your skin will be lighter, brighter and with an even skin tone.

Moreover, Vitamin C helps in skin cell renewal, leaving your skin look fresher, brighter and cleaner. 

Vitamin C also aids in the skin whitening process by making skin cells more susceptible to the effects of glutathione. Whereas, glutathione is widely famous for skin brightening and detoxification.
