What Is Vitamin C?
Vitamin C is a well-known antioxidant vitamin. Pure vitamin C breaks down quickly in air and light, so many products use steadier forms, such as sodium ascorbyl phosphate.
What It Does in Skin and Hair Care
In skincare, vitamin C is used for a fresher, brighter-looking complexion. It is a favourite in brightening products, often together with licorice extract and niacinamide.
How to Use Products With It
- Use as part of your morning or evening routine, as the label says.
- In the morning, always follow with sun care.
- Close the lid tightly and keep the product away from heat and sunlight, which can spoil vitamin C.
Tips and Cautions
- Some forms of vitamin C can sting on sensitive skin. Patch test first: put a little on the inside of your arm for a day or two before using it on your face or body.
- If your skin stays red, itchy or sore, stop using the product and see a doctor.
Questions
- What is sodium ascorbyl phosphate?
- It is a steadier form of vitamin C that holds up better in a cream than pure vitamin C.
