DID YOU KNOW?

Skin is different at night.

Protect by day. Renew by night.

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

YOUR SKIN
Every Day

  • • Protects
  • • Has a stronger, thicker barrier
  • • Produces the most oil
  • • Has a higher pH level

It strengthens its protective defenses
against environmental assaults.

YOUR SKIN

Every Night

  • • Renews itself following the damage of the day
  • • Is more prone to moisture loss
  • • Produces the most collagen
  • • Has a more permeable barrier

It re-energizes with its critical renewal process that peaks while we sleep.

When your skin’s “clock” and critical night renewal are disrupted by everyday life—a busy calendar, endless scrolling and especially poor sleep—it shows on skin.

Pioneering Sleep Science

Poor Sleep. Skin Aging.
What’s the Connection?

In a first-ever clinical study with Case Western Reserve, Estée Lauder showed that poor sleep can double signs of aging.

The solution? Advanced Night Repair Serum with our exclusive Night Peptide. It strengthens skin’s barrier. Intensely hydrates. Visibly evens skintone and reduces the look of lines.

Pioneering Sleep Science:
Continuing The Legacy

A recent endowment from Estée Lauder has established an epigenetics fellowship at The University of California, Irvine in honor of the late Paolo Sassone-Corsi, PhD. Paolo worked with Estée Lauder to explore new discoveries in skin science including its circadian rhythm.

What happens to skin overnight?

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.

What are the benefits of sleep for skin?

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.

What has Estée Lauder discovered about the connection between sleep and skin?

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.
