Kiehl's Ultra Facial Overnight Hydrating Face Mask — 3.4 fl oz, 10.5% Squalane & Barrier-Strengthening

Kiehl's Ultra Facial Overnight Hydrating Face Mask is an intensive leave-on balm-to-oil treatment that deeply replenishes dry, flaky skin overnight and helps strengthen the skin’s moisture barrier.

This paraben-free, fragrance-free mask is formulated with 10.5% squalane and Glacial Glycoprotein to restore essential lipids and lock in moisture while you sleep. Designed to melt into skin from a rich balm into a lightweight oil, the formula targets visible dryness and flaky texture without leaving a heavy, pore-clogging residue. Clinically inspired to support barrier resilience, the mask also helps skin feel softer and more comfortable for days after one application.

How does the balm-to-oil texture work while I sleep?

The product starts as a concentrated balm that transforms into an oil when gently massaged, allowing active ingredients to spread evenly and absorb into skin. This change in texture helps deliver squalane and glacial glycoprotein where they can replenish lipids and reduce surface dryness.

• Massage until balm melts into oil for optimal absorption.
• Pat excess into face, neck, and chest—no rinsing required.
• Designed for overnight use to deliver sustained hydration while you rest.

Will this mask clog pores or feel greasy on my skin?

The formulation is non-comedogenic and non-sticky, created to feel nourishing without a heavy, greasy finish. Users typically report a comfortable, supple feel and reduced tightness or flakiness without a pore-blocking sensation.

• Non-comedogenic formula minimizes risk of clogged pores.
• Light oil finish avoids an overly shiny or sticky feel.
• Suitable for layering under night creams or alone for intensive treatment.

How long will the hydrating effects last after one application?

One overnight treatment can help prevent visible dryness for up to three days, as the mask replenishes key skin lipids and supports the moisture barrier. Results vary by skin condition, but the intent is longer-lasting comfort and improved barrier resilience.

• Helps reduce flakiness and dryness for multiple days.
• Squalane restores lipids that assist moisture retention.
• Ideal for periodic intensive care or targeted winter use.

How should I use this mask with my existing skincare routine?

Use the mask as the final step of your evening routine on clean, dry skin. Gently massage until it melts and pat in any excess; do not rinse. It can be used alone or a few times weekly as needed to address dryness and strengthen barrier function.

• Apply at night after cleansing and serum application.
• Massage into face, neck, and chest; leave on overnight.
• Use 1–3 times weekly or whenever skin feels especially dry.
