Niacinamide doesn't necessarily need to be used at night, but it's often recommended as part of a nighttime skincare routine because, unlike some other actives like retinol, it doesn't increase your skin's sensitivity to the sun.
Here's a breakdown:
-
Sun Sensitivity: Niacinamide is generally well-tolerated and doesn't make your skin more susceptible to sun damage. This is a key difference from ingredients like retinoids, which require careful sun protection.
-
Flexibility in Application: Niacinamide can be used both in the morning and at night, up to twice a day. You can integrate it into your routine whenever it best suits your needs.
-
Nighttime Routine Integration: Many people choose to incorporate niacinamide into their nighttime routine as part of a comprehensive skincare regimen. This allows it to work synergistically with other nighttime products.
In summary, while there's no specific reason necessitating niacinamide use at night, its compatibility with other nighttime ingredients and lack of sun sensitivity makes it a convenient and effective addition to your evening skincare routine.
