COSRX Lip Butter Sleeping Mask — Intensive Shea & Ceramide Night Treatment for Dry, Chapped Lips (Fragrance-Free)

COSRX Lip Butter Sleeping Mask is a rich ceramide and shea butter treatment designed to restore and seal moisture into dry, chapped lips overnight.

This concentrated lip butter from COSRX combines Ceramide NP with nourishing butters and oils to rebuild the lips' moisture barrier while you sleep. Its thick, emollient texture forms a protective layer that locks in hydration and helps soften rough, flaky patches without synthetic fragrances or parabens.

How does this lip butter restore moisture while I sleep?

The formula uses ceramide to support the skin barrier and emollients like shea and coconut oil to replenish lip lipids. Applied before bed, the product creates an occlusive layer that reduces overnight moisture loss so lips wake feeling softer and smoother.

• Ceramide NP for barrier support
• Shea butter and coconut oil to nourish and soften
• Thick, butter-like texture that seals in hydration
• Overnight application maximizes absorption and protection

Can I use this during the day under or over lipstick?

Yes—the buttery formula can be layered under lip color for a hydrated base or dabbed on top of makeup to add shine and comfort. Because it is free from artificial fragrance, it won’t interfere with scent-sensitive routines.

• Wear under matte lipsticks to prevent flaking
• Apply over lipstick for a glossy, moisturized finish
• Non-irritating formula suitable for sensitive lips
• Hypoallergenic and dermatologist-tested

What ingredients should I expect, and are there any harsh additives?

The ingredient list focuses on skin-friendly lipids and oils—Ceramide NP, shea butter, coconut oil and jojoba seed oil—chosen to replenish and protect. COSRX avoids parabens, sulfates, phthalates and artificial fragrances, and the product is not tested on animals.

• Key actives: Ceramide NP, Shea Butter, Coconut Oil, Jojoba Seed Oil
• Free from parabens, sulfates, phthalates, and synthetic fragrance
• Dermatologist-tested and cruelty-free labeling
• Designed for nightly restorative use

How should I apply it for best results?

For overnight recovery, apply a generous layer before bed to allow the ingredients to penetrate and protect while you sleep. During the day, use a thinner coat under or over lipstick to maintain softness and prevent dryness.

• Night: apply thickly to cleansed lips before sleeping
• Day: use a light layer under or over lip color as needed
• Reapply to very dry patches for targeted care
• Store in a cool place to preserve buttery consistency

Who this is for: COSRX Lip Butter Sleeping Mask is suited to anyone with dry, peeling, or easily irritated lips who wants a fragrance-free, dermatologically-minded treatment. It’s a good pick for fragrance-sensitive users, those who prefer cruelty-free skincare, and anyone seeking a simple, effective overnight lip repair step that also works under makeup.
