The best time to apply vitamin C serum is generally in the morning, after cleansing and toning your face, and before applying moisturizer and sunscreen. This allows the vitamin C to provide antioxidant protection against environmental damage and boost the effectiveness of your sunscreen throughout the day. However, vitamin C serum can also be applied at night to help support the skin's natural repair process while you sleep, which can be especially beneficial for collagen stimulation and skin regeneration. If you have sensitive skin, you might want to use the serum only at night to avoid potential irritation exacerbated by sun exposure during the day. Some people also choose to apply vitamin C serum both in the morning and at night to maximize benefits, although this depends on skin type and tolerance. Summary of key points on when to apply vitamin C serum:
- Morning application: After cleansing and toning, before moisturizer and sunscreen, for daily antioxidant protection and enhanced sun protection.
- Night application: Supports skin repair and collagen production during sleep.
- Both morning and night: Possible for maximum benefits if skin tolerates it.
- For sensitive skin: Prefer night use to minimize irritation risk.
- Always follow with sunscreen during the day to protect skin as vitamin C may increase photosensitivity.
