COSRX Ceramide Lip Butter Sleeping Mask — Shea Butter Overnight Lip Balm, Deep Hydration & Barrier Repair

COSRX Ceramide Lip Butter Sleeping Mask is a rich, shea-butter and ceramide‑enriched lip balm designed to protect and deeply hydrate dry, chapped lips overnight.

Formulated by COSRX with skin‑friendly ingredients, this lip butter combines Ceramide NP, Shea Butter, Coconut Oil and Jojoba Seed Oil into a thick, emollient texture that seals in moisture while you sleep and smooths the lip surface for daytime wear. It is free from artificial fragrances, parabens, phthalates and sulfates, and is not tested on animals. Use it as an overnight sleeping mask or a protective daytime balm over or under lip color.

How does the Ceramide Lip Butter protect lips while I sleep?

The formula uses Ceramide NP to help support the skin’s natural barrier and a high concentration of shea butter to lock in hydration. A dense, buttery texture creates an occlusive layer that reduces moisture loss during the night without feeling oily. Regular nighttime use helps reduce the look of roughness and flaking by morning.

• Ceramide NP: reinforces the lip barrier for moisture retention
• Shea Butter: intensely emollient to soften and reduce flaking
• Occlusive texture: prevents transepidermal water loss while you sleep

Can I wear it during the day and under lipstick?

Yes — the buttery balm works as a daytime lip protector and as a smoothing base for lip makeup. Apply a light layer to create a plump, hydrated canvas before lipstick or gloss. For fuller coverage, dab a thin coat over lip color to prevent feathering and extend wear.

• Light daytime layer: creates a smooth base for lip products
• Over makeup: seals color and reduces feathering
• Portable use: keeps lips comfortable in dry environments

What key ingredients should I expect and what do they do?

The ingredient list focuses on barrier support and emollience rather than active exfoliants. Ceramide NP helps restore lipid layers; shea butter supplies deep moisturization; coconut and jojoba oils add absorption and a silky feel. The product intentionally excludes artificial fragrances and common irritants for sensitive lips.

• Ceramide NP: barrier support and moisture lock
• Shea Butter: long‑lasting emollience and softening
• Coconut Oil & Jojoba Seed Oil: lightweight conditioning and glide
• No fragrances, parabens, sulfates or phthalates: lower irritation risk

How do I use COSRX Lip Butter for best results?

For overnight treatment, apply a generous layer before bed to let the formula absorb while you sleep. During the day, use a thin layer over or under lip color to protect and smooth. Reapply as needed in dry conditions or whenever lips feel tight.

• Night: thick layer as a sleeping mask for intensive repair
• Day: light application under or over lipstick for added comfort
• Frequent reapplication: ideal in cold, windy or heated environments
