What Sephora says

What this product is supposed to do

A fragrance-free hydrating face mask with 10.5% squalane for dry skin that locks in moisture overnight and strengthens skin’s moisture barrier.

Normal and DryDryness

After cleansing at night, use fingertips and apply a generous layer of this hydrating face mask onto clean skin.

Gently massage onto skin until texture transforms from balm to oil, allowing the formula to melt into skin.

Pat excess onto skin, neck, and chest and do not rinse.

Allow to work overnight, and in the morning, follow your normal regimen.

We recommend using this overnight face mask three times per week.

Packaged in a 100% post-consumer recycled jar.
