Yes, you can use serum at night. In fact, nighttime application offers several benefits.
Nighttime Serum Application: Advantages
- Enhanced Absorption: While you sleep, your skin's repair processes are most active. Applying serum at night allows for optimal absorption of beneficial ingredients while your skin is in this restorative state.1, 5, 7
- Reduced Sun Sensitivity: Some serums, particularly those containing ingredients like AHAs and retinol, can increase your skin's sensitivity to sunlight. Using these serums at night avoids potential sun damage.1
- Stress-Free Application: Using serum at night simplifies your skincare routine, freeing up your morning time.1
- Overnight Action: Many serums are specifically formulated to work overnight, maximizing their effectiveness while you sleep. Products like "night serums" or those with "overnight" in their name highlight this intended use.3, 8, 9
Daytime Serum Application: Considerations
While nighttime application is often preferred, many serums can be used during the day. However, always consider the serum's ingredients. Those sensitive to sunlight should be reserved for nighttime use.1
Choosing the Right Serum
The best time to apply serum depends on the specific product and its ingredients. Always read the product label for instructions. Some serums are explicitly designed for daytime or nighttime use, while others are suitable for both.2, 3
Application Technique
Regardless of the time of day, apply serum to clean skin. This ensures optimal absorption of the serum's ingredients.2
