How to Choose a Vitamin C Serum: Forms, Strengths and How to Use It
Vitamin C is an antioxidant used to support the look of brighter, more even-toned skin. Choosing one comes down to form, strength and texture. For the basics, see what vitamin C is.
Know the form
L-ascorbic acid is the most researched form and can feel stronger on the skin. Derivatives are often gentler and may suit sensitive skin better.
Pick your texture and strength
- Everyday serums: Verso Super C Serum and Votary Vitamin C Glow Serum.
- Higher strength, for experienced users: Melumé Super C-Shot 25% Serum.
- Creams and oils: VerdiLab Natural Glow Vitamin C Brightening Cream and Oio Lab The Future Is Bright facial oil.
- Eyes: VerdiLab Ultimate Lightening Vitamin C Eye Elixir.
How to use it
Apply in the morning before moisturiser and SPF, introduce it gradually and patch test first. Because vitamin C and retinol can degrade each other, many routines use vitamin C in the morning and retinol at night.

Vitamin C serums: 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 stop if irritation occurs.
How long does vitamin C take to work?
Effects build gradually with consistent use over several weeks, and results vary. Daily SPF helps protect them.
