Does the Time of Day Really Matter? 

Yes, timing does matter in skincare. Your skin follows a 24 hour circadian rhythm, meaning its needs and behaviour changes according to the time of day vs night. 

Morning Use

• Your skin is in defence mode

• Antioxidants like vitamin C help shield your skin from oxidative stress and environmental stressors like pollution, UV rays.

• Oil-regulating ingredients such as niacinamide works best to reduce excess shine and grease as sebum regulation peaks in the afternoon 

• Niacinamide is a sun-stable ingredient, meaning it does not degrade under UV exposure. 

 Evening Use

• In the evening, your skin is in repair and recovery mode, accelerating cell turnover and healing damage

• Ingredients like retinol are recommended for night use as are highly sun sensitive and they help accelerate cell turnover

• Ingredients such as niacinamide are highly recommended even for PM use, as it accelerates cell turnover and strengthens barrier repair and function, soothens and calms skin 

Should you use Niacinamide serum in the morning or at night?

Niacinamide can generally be incorporated into either a morning or evening skincare routine, depending on your preferences and the rest of your regimen. But it is deemed safe for both AM and PM use. The most important factor is using it consistently according to the product's directions, and your skin’s tolerance to the active.
