Vitamin C Serum for Face: the Different Types of Vitamin C

Ascorbic Acid

No matter if you have sensitive skin or a normal skin type, this vitamin C is perfect for you. However, normal skin types should use this acid with a pH of less than 4, while sensitive skin people should use it with pH 5-7. 

If you have stubborn skin problems, then the concentration of the ascorbic acid to use should be around 15%-20%.

  • Neutralizes free radicals
  • Boost collagen production
  • Removes scars 


  • Can oxidize quickly (vitamin C in itself is sensitive to light and air)
  • Can cause skin irritation 

Sodium Ascorbyl Phosphate

Sodium Ascorbyl Phosphate is a water-soluble and stable derivative of Vitamin C, which is usually used in 0.1-2% concentration for daily use. It contains anti-inflammatory properties and also works as a skin whitening agent. It usually comes in a pH of 6-7%. Unlike ascorbic acid, it does not oxidize quickly. Hence, sodium ascorbyl phosphate can be used for a long time in serums and is used in some of the best vitamin c serum for face.
