Kiehl's Since 1851 Ultra Facial Overnight Hydrating Face Mask

What it is: An intensively hydrating face mask for dry skin that helps replenish and strengthen skin's moisture barrier.

Who it's for: All skin types.

What it does: It helps increase barrier stability and prevents excess overnight moisture loss. Infused with 10.5% squalane, this transformative balm-to-oil formula melts into skin and helps boost resilience against external aggressors. It helps prevent dryness for up to three days so you wake up to skin that's nourished, flake-free and healthy-looking.

Research results:

In a consumer use study on 95 subjects after two weeks:

- 93% agreed skin felt deeply hydrated

In a consumer use study on 95 subjects after one week:

- 90% agreed skin looked flake-free

- 84% agreed skin felt less tight

How to use: After cleansing, use your fingertips to apply a healthy layer to clean skin. Gently massage into your skin until its texture transforms from a balm to oil, allowing the formula to melt into skin. Pat in excess. Do not rinse. Allow to work overnight and in the morning follow with your regular skin care routine. Kiehl's recommends using this mask three times per week.
