Obagi Hydrate Luxe 48g

Have you ever heard of a circadian rhythm? It’s the physical, mental and behavioral changes in your body that follow a roughly 24-hour cycle, such as your sleeping schedule.1 What you may not realize is that many of your skin functions also follow a circadian rhythm. While you may begin to unwind in the evening, your skin is hard at work and actually increases its renewal and metabolic functions at night.

Consider these cycles in your skin’s functions that may influence its texture, radiance, and overall appearance:2

Cell proliferation peaks at midnight, and is lowest at noon
Blood flow is 25% lower at night
Oil production by skin glands is higher midday at noon
Skin pH is more acidic during sleep
