[Vitamin C](/blogs/ingredients/vitamin-c-for-your-skin-the-benefits-of-this-powerful-antioxidant) serum is most commonly recommended for morning use due to its antioxidant properties. But can you use it at night? Absolutely! Using [Vitamin C](/blogs/ingredients/vitamin-c-for-your-skin-the-benefits-of-this-powerful-antioxidant) serum at night allows it to work while your skin is in repair mode. Nighttime is when skin cells regenerate fastest, making it an excellent time for active ingredients like [Vitamin C](/blogs/ingredients/vitamin-c-for-your-skin-the-benefits-of-this-powerful-antioxidant) to penetrate deeply and support collagen synthesis.

### **Benefits of Using [Vitamin C](/blogs/ingredients/vitamin-c-for-your-skin-the-benefits-of-this-powerful-antioxidant) at Night**

#### **1\. Boosts Collagen Production While You Sleep**
