How to choose a vitamin C serum that actually works
Strength, form and packaging all matter. How to pick a vitamin C serum and fit it into your routine.
Quick answer: Choose a stable vitamin C serum in opaque, airtight packaging, start at 10% to 15% and use it every morning under SPF. Increase strength only if your skin tolerates it.
What vitamin C does
Vitamin C is an antioxidant that neutralises damage from UV and pollution, brightens dull skin, fades pigmentation and supports collagen.
Strength
Around 10% to 20% is the effective range. Higher is not always better, as sensitive skin may sting. Obagi Professional-C comes in 10%, 15% and 20% so you can build up.
Using it
Apply to clean, dry skin in the morning, follow with moisturiser and finish with SPF. Vitamin C and SPF work together for better protection.
Storage
Vitamin C breaks down with light and air. Keep the lid on and use the bottle within a few months of opening.
Common questions
Can I use vitamin C with retinol?
Yes, use vitamin C in the morning and retinol at night.
