The general recommendation for using vitamin C serum is that most people can safely apply it once daily, ideally starting with this frequency to see how the skin reacts. Some individuals use it twice a day (morning and night) for faster and enhanced results if their skin tolerates it well. For those with sensitive skin or new to vitamin C, starting 2-3 times a week or every other day and then gradually increasing is advisable to avoid irritation. Always follow with sunscreen during the day since vitamin C can increase skin sensitivity to sunlight. Key points:
- Start with once daily use, preferably in the morning to protect against daily environmental damage.
- If skin tolerates well, increase to twice daily use for protection and repair benefits.
- Sensitive skin may require less frequent use, such as every other day or 3-4 times a week.
- Consistency is important for long-term brightening, anti-aging, and skin health benefits.
- Always apply sunscreen during the day when using vitamin C serum.
In summary, commonly recommended usage is daily, once or twice depending on skin tolerance, with gradual introduction for sensitive skin and consistent daily use for best results.
