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 Balancium Ceramide Lip Butter Sleeping Mask
What is this sleeping mask for?
Shea butter is the second ingredient on this balm's list, right behind bis-diglyceryl polyacyladipate-2, with coconut, castor and jojoba oils and mango seed butter following further down. Ceramide NP and phytosphingosine appear near the end of the list, supporting the feel of a smoother lip barrier. It is an overnight, leave-on step for lips that feel dry or chapped by the end of the day.
Is this mask suitable for very reactive or sensitive lips?
No fragrance, essential oil, denatured alcohol, silicone or added colourant appears on this ingredient list, which keeps the formula relatively simple for lips that are already reactive. The base runs on butters and waxes, shea, coconut, castor and jojoba among them, plus beeswax and candelilla wax, rather than anything acid-based or actively exfoliating.
How many nights before I notice softer lips?
This is a dense, occlusive balm meant to sit on lips overnight, so a single application can feel supple by morning, but the softer feel depends on wearing it consistently through repeated nights rather than one use fixing chronic dryness. Any residue left on the lips in the morning is fine to work into dry cuticles rather than wasted.
Can I use a lip scrub before this mask?
Yes, since this mask is a leave-on overnight step with no exfoliating ingredient on its own list, using a lip scrub earlier in the evening to clear flaking skin first is a reasonable pairing rather than a conflict. Apply the mask as the very last step before sleep, after any scrub has been rinsed away.

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.
