What to look for in a Vitamin C Serum

Vitamin C is an antioxidant that helps with pigmentation, sun damage, and dullness. Form, concentration, and packaging all affect stability and effectiveness.

Quick checklist

• Form: L-ascorbic acid is most studied; derivatives are gentler and more stable.
• Concentration: 10–20% for efficacy; over 20% irritates without added benefit.
• Packaging: amber/opaque bottles protect from light oxidation.
• Pair with SPF: vitamin C amplifies sunscreen's protection: use daily.
