How it works
An overnight lip mask is a texture decision before it is anything else: it has to stay in place for hours without being licked or blotted away. This is the butter in COSRX's Balancium line, dense enough to sit on the lips through the night rather than sink in and disappear. It goes on last, after the evening routine, in a layer thick enough to see. Lips carry no oil glands of their own, so overnight they lose water to the air unless something is over them. Nightly, or on the nights lips feel tight, and the leftover on a fingertip is worth putting on dry cuticles.
Key benefits
- Shea butter is the second ingredient in an oil-and-butter base
- Ceramide NP supports the feel of a smooth, cared-for lip barrier
- Coconut, castor, jojoba oils and mango seed butter carry the cushion
- A thin layer at night leaves lips supple by morning

COSRX Lip Sleep - Balancium Ceramide Lip Butter Sleeping Mask
What does this lip sleeping mask do?
Shea butter sits second on the ingredient list, just after bis-diglyceryl polyacyladipate-2, with coconut, castor and jojoba oils and mango seed butter following further down. Ceramide NP and phytosphingosine close out the list, supporting the feel of a smoother lip surface. This is a leave-on overnight step for lips that end the day feeling dry.
Is this too rich for sensitive lips overnight?
The list contains no fragrance, essential oil, denatured alcohol or added colourant, keeping the formula relatively plain for lips prone to reacting. The richness comes from butters and waxes, shea, coconut, castor and jojoba plus beeswax and candelilla wax, rather than any acid or actively exfoliating ingredient, so there is nothing on the list built to irritate.
Will I see results after one night, or does it take time?
A single overnight application can leave lips feeling supple the next morning, since the balm sits against lips for hours, but chronically dry lips generally need consistent nightly use rather than a one-time fix. Any leftover balm on the lips by morning can be worked into dry cuticles instead of going to waste.
Can I use a scrub before applying this mask?
Yes, this mask itself carries no exfoliating ingredient, so using a separate lip scrub earlier in the evening to clear rough patches first pairs naturally with it. Apply the mask as the last step before bed, after any scrub has been rinsed off.
How can I tell this is the real Korean-market formula?
COSRX verifies units on its own portal rather than through a reseller: locate the batch number and expiration date printed on this tube and enter them on the verification page at cosrx.com. The barcode printed on this tube is 8809598453388.

How to use
- Use the Balancium Ceramide Lip Butter Sleeping Mask as the last thing before bed, on clean lips.
- A thick layer, more than a daytime balm, taken to the lip line and then left alone.
- It goes on after the evening routine is finished, and nothing goes over the top of it.
- Nightly, or on the nights lips feel tight. Do not blot it off before sleeping; it needs the whole night in place.
Worth knowing
- Beeswax is on the list, so this is not a vegan formula.
