COSRX Ceramide Lip Butter Sleeping Mask — Shea Butter Overnight Repair, Fragrance-Free Balm

COSRX Ceramide Lip Butter Sleeping Mask is an intensive, overnight lip treatment that combines ceramide and shea butter to restore and protect dry, chapped lips.

This lip butter is formulated to rebuild the lip skin barrier and deliver long-lasting hydration without synthetic fragrances, parabens, sulfates, or animal testing. Designed by the Korean skincare brand COSRX, the formula blends Ceramide NP with rich emollients like shea butter, coconut oil, and jojoba seed oil to soften, soothe, and help lips retain moisture through the night and into the day.

How does this lip butter work while I sleep?

Applied before bed, the thick, buttery texture forms a protective layer that helps reduce overnight moisture loss and supports the lips’ natural repair processes. The ceramide component helps reinforce the lipid barrier, while oils and butters provide emollient sealing and comfort.

• Ceramide NP to support skin barrier resilience.
• Shea butter for deep, slow-release moisturization.
• Coconut and jojoba oils to soften and reduce flaking.
• High-occlusive texture that minimizes water evaporation overnight.

Can I use this during the day under or over lip makeup?

Yes — the formula is versatile for daytime use. Apply a thin layer under lipstick to create a smoother base or dab a light coat over lipstick or gloss for added shine and hydration.

• Use a light layer for wearability with lip color.
• Apply a thicker coat for a glossy, protective top layer.
• Non-fragranced finish reduces interference with scented lip products.

Is this product suitable for sensitive or allergy-prone skin?

The balm is designed with skin-friendly ingredients and avoids common irritants like artificial fragrances, parabens, sulfates, and phthalates. It is dermatologist-tested and formulated to be hypoallergenic, though patch testing is advised for individual sensitivities.

• No artificial fragrance to reduce irritation risk.
• Free from parabens, sulfates, and phthalates.
• Dermatologist-tested and cruelty-free production.
• Recommended patch test if you have specific ingredient allergies.

How long before I see improvement in chapped lips?

Many users notice immediate smoothing and reduced tightness after the first application, with more visible repair and fewer flakes after several nights of consistent use. Continued nightly application helps maintain moisture and prevent recurring dryness.

• Immediate: softer, less tight feeling after one use.
• Short-term: reduced flaking and smoother texture within days.
• Long-term: improved barrier function with regular nightly use.

Who is this for: COSRX Ceramide Lip Butter Sleeping Mask is ideal for people with chronically dry or seasonally chapped lips, those who prefer fragrance-free formulas, and anyone looking for a barrier-repair focused overnight treatment. It suits users seeking a cruelty-free, dermatologist-tested lip solution that doubles as a daytime smoothing balm under or over makeup.
