Kiehl's Ultra Facial Overnight Hydrating Face Mask — 10.5% Squalane, 3.4 fl oz balm-to-oil intense hydration

Kiehl's Ultra Facial Overnight Hydrating Face Mask is an overnight balm-to-oil mask formulated with 10.5% squalane to deeply replenish moisture and support the skin's barrier while you sleep.

This rich, non-fragrant treatment is designed to transform dry, tight, or flaky skin by delivering concentrated hydration and lipid-replenishing actives overnight. The formula melts from a balm into an oil on contact with skin, letting emollients sink in without leaving a heavy, pore-clogging residue. Paraben-free and non-comedogenic, it was honored with Allure Best of Beauty recognition for its ability to restore comfort and visible smoothness.

How does this mask hydrate without feeling greasy?

The product uses a high concentration of squalane (10.5%) combined with supportive hydrating ingredients that emulate the skin's natural lipids, so moisture is locked in without a slick surface residue. The balm-to-oil texture allows active ingredients to absorb more fully than a traditional cream.

• Squalane replenishes lipids to soften and smooth skin.
• Glacial glycoprotein helps retain surface moisture for prolonged hydration.
• Non-comedogenic formulation minimizes pore congestion.
• Transforms texture for efficient absorption overnight.

When and how should I use it for best results?

Apply at night as the final step of your evening routine on clean, dry skin. Massage the balm until it converts to an oil, then gently pat excess into the face, neck, and chest; leave on to work while you sleep and do not rinse.

• Use nightly or as needed for intense hydration.
• Massage until balm becomes oil to improve absorption.
• Pat into skin—no rinsing necessary—allow overnight action.
• Can be layered over serums or lightweight moisturizers.

What skin concerns does it address and how quickly will I see change?

This mask targets dryness, tightness, and flaky texture by replenishing essential lipids and bolstering the moisture barrier. Many users report reduced visible dryness after one use and improved comfort lasting for days, while sustained use supports overall barrier resilience.

• Reduces flakiness and visible dry patches overnight.
• Helps skin feel softer, smoother, and less tight.
• Supports barrier function to resist environmental stressors.
• Helps maintain hydration for up to three days with regular use.

Is it safe for sensitive or acne-prone skin?

The formula is fragrance-free, paraben-free, and non-comedogenic, making it suitable for many sensitive and acne-prone skin types. As with any concentrated treatment, patch testing is recommended if you have reactive skin or specific ingredient sensitivities.

• Fragrance-free to minimize irritation risk.
• Non-comedogenic to reduce likelihood of breakouts.
• Gentle balm-to-oil texture avoids heavy occlusion.
• Patch test if you experience sensitivity to rich oils.

Who is this for: Kiehl's Ultra Facial Overnight Hydrating Face Mask is aimed at anyone with dry, tight, or flaky skin who wants an intensive overnight repair treatment that feels nourishing without clogging pores. It suits those looking for a fragrance-free, paraben-free option to strengthen the skin’s moisture barrier—ideal for seasonal dryness, travel, or when skin needs extra replenishment. If you prefer light daytime textures, use this mask at night as a focused boost for hydration and barrier support.
