Kiehl's Ultra Facial Overnight Hydrating Face Mask — 3.4 fl oz, 10.5% Squalane, Balm-to-Oil Deep Hydration

Kiehl's Ultra Facial Overnight Hydrating Face Mask delivers concentrated overnight hydration with 10.5% squalane to replenish, comfort, and help strengthen the skin’s moisture barrier while you sleep.

This rich, balm-to-oil overnight mask from Kiehl's is formulated to target dryness, tightness, and flaky skin without fragrance or parabens. Designed for nightly use as a leave-on treatment, the formula melts into skin to boost lipid levels and help lock in moisture for up to three days. Lightweight despite its nourishing feel, the product is non-comedogenic and suitable for all skin types, including those prone to dryness and environmental stressors.

How does this mask hydrate skin while you sleep?

The texture transforms from a balm to an oil when massaged in, enabling active ingredients to spread evenly and absorb overnight. Squalane replenishes essential lipids and glacial glycoprotein supports moisture retention, working together to minimize visible flakiness and dryness by morning.

• 10.5% squalane to restore skin lipids.
• Glacial glycoprotein to help bind and retain moisture.
• Balm-to-oil texture for deep overnight absorption.
• Non-sticky, non-comedogenic finish that won’t clog pores.

How should I use it for best results?

Apply in the evening to clean, dry skin and gently massage until the balm melts into oil. Pat any remaining oil into the face, neck, and chest and leave on overnight — do not rinse — to let the formula work while you sleep.

• Apply a thin, even layer as the final step in your nighttime routine.
• Massage until texture transforms and pat excess into skin.
• Use nightly or as needed for intense hydration cycles.
• Suitable for use under light sleepwear; avoid contact with eyes.

Will it feel greasy or clog my pores?

Despite a nourishing, oil-like finish, the mask is formulated to feel comfortable and non-greasy on skin. Kiehl's designed it to be non-comedogenic, so it hydrates deeply without leaving a heavy residue or contributing to pore congestion for most skin types.

• Light, melting texture that absorbs overnight.
• Non-comedogenic formula suitable for many skin types.
• Fragrance-free to reduce irritation risk for sensitive skin.
• Leaves skin feeling soft rather than oily.

How long do hydration benefits last after one application?

The formula helps support skin moisture levels for up to three days after application, helping reduce visible dryness and flakes. Regular overnight use can build and maintain a stronger moisture barrier for improved resilience over time.

• Immediate overnight replenishment and comfort.
• Reported hydration benefits lasting up to three days.
• Supports the skin’s natural barrier to retain moisture longer.
• Best results with consistent, repeated nightly use.

Who is this for: Kiehl's Ultra Facial Overnight Hydrating Face Mask is ideal for anyone experiencing dry, tight, or flaky skin who wants an easy, leave-on overnight treatment. It's especially useful for seasonal dryness, travel-related dehydration, or anyone looking to strengthen their skin barrier without added fragrance or parabens. Because the formula is non-comedogenic and formulated for broad compatibility, it suits most skin types seeking deeper overnight hydration and a softer, more comfortable feel by morning.
