[Product Question] Vitamin C Questions SkincareAddiction

1. Should I keep vitamin c in the refrigerator?

2. It says vitamin c provides sun-protection. But how much though, I should probably still use sunscreen right?

3. How often should I use vitamin c? The sidebar information says vitamin c stays on your skin for two days and can't be washed off. So should I use it every 2 days?

4. Why don't all vitamin c serums come in spray form so that it doesn't oxidizes and last longer? Can it be said that sprays and other deliver system that minimize air exposure is superior?
