What Is Vitamin C in Skincare? Forms, Benefits and How to Use It
Vitamin C is an antioxidant used in skincare to support the look of brighter, more even-toned skin. It is usually used in the morning under SPF.
What it is used for
Vitamin C is used to help skin look radiant, to support the look of an even tone and dark spots, and to help protect against environmental stress as part of a daily routine.
The main forms
L-ascorbic acid is the most researched form and can feel stronger on the skin. Derivatives such as magnesium or sodium ascorbyl phosphate are often gentler and may suit sensitive skin better.
How to use it
Apply after cleansing and before moisturiser and SPF, introducing it gradually. It can pair with niacinamide and hyaluronic acid. Many routines keep retinol for night.

Vitamin C: frequently asked questions
Should I use vitamin C in the morning or at night?
Most routines use it in the morning under SPF, though it can be used at night if it suits your skin.
Is vitamin C suitable for sensitive skin?
Gentler derivatives may be better tolerated. Start with a low strength a few times a week and patch test first.
