Skin is different at night.


Protect by day.
Repair by night.

Like our entire body, skin has a natural
circadian rhythm. It has very different
actions during the day versus the night.

sleep science and expertise.


  • Skin is biologically different from day to night. Every night, your skin repairs damage and re-energizes. It is also more prone to moisture loss and has a thinner, more fragile barrier. That’s why we recommend having a dedicated nighttime routine, made with ingredients that can deliver powerful renewing benefits overnight.


  • Skin renews itself at night, and this process peaks while you sleep. Getting enough quality, uninterrupted sleep each night is essential in waking up with beautiful, glowing skin and helping prevent visible signs of aging.


  • With 40 years of research and discoveries, our Estée Lauder scientists are experts in night sleep science. Our first-ever clinical study unveiled that sleep-deprived skin can experience a weaker barrier and dryness, loss of firmness, a more uneven skintone and increased lines.
