## Questions & Answers

**Q: What are the benefits of a vitamin C serum?**
A: Vitamin C is an essential nutrient that moisturises the skin and helps combat signs of ageing and pigmentation spots. A vitamin C serum is the perfect addition to your skincare routine as it can act directly on the skin.

**Q: How can you recognise a high-quality vitamin C serum?**
A: Make sure there is a sufficient concentration of real vitamin C. Other ingredients such as hyaluronic acid enhance the anti-ageing effect. Choose a serum in a dark bottle to preserve the effect of the photosensitive vitamin.

**Q: When is the best time to use a vitamin C serum?**
A: Apply the vitamin C serum once a day, either in the morning or in the evening. Cleanse the face first and then apply the serum. Follow with a day or night cream. A day cream with SPF is recommended during the day.
