There's no single "better" time, but dermatologists generally recommend applying vitamin C serum in the morning.
Why Morning?
- Sunlight Protection: Vitamin C is a potent antioxidant that helps protect your skin from sun damage. Applying it in the morning creates a layer of defense against UV rays encountered throughout the day. This synergistic effect with sunscreen enhances its protective properties.
- Enhanced Absorption: Some studies suggest that vitamin C may be more effectively absorbed by the skin when applied in the morning, although more research is needed to definitively confirm this.
- Improved Efficacy: The combination of morning application and sun protection maximizes the benefits of vitamin C's antioxidant and collagen-boosting properties.
Nighttime Application: Not Necessarily Ineffective
While morning application is generally preferred, applying vitamin C at night isn't inherently wrong. It still offers antioxidant benefits, working to repair any damage incurred during the day while you sleep. However, the benefits of sun protection are lost if applied at night.
Conclusion: Morning Application is Optimal
While vitamin C offers benefits regardless of application time, its antioxidant and sun-protective qualities are best utilized when applied in the morning. Therefore, a morning routine is recommended for optimal results. This is consistent with the nearly universal recommendation from dermatologists that vitamin C serums should be incorporated into your morning skincare routine.
