The one you leave on

Overnight masks

Thirteen masks, eight of them Korean, and the only group here where every per-use price is an estimate: a jar does not tell you how many nights it holds. The lists sit exactly on the catalogue's median at 26 ingredients, and butylene glycol is on all but one of them. What separates the format is not length but what sits near the top of the list.

Prices are indicative, captured once from the source recorded on each product page, and they drift. Every per-use figure here is estimated from pack size at a typical application rather than counted off a sheet count.

The short read

  • Every one of the 13 per-use figures is an estimate. A sheet mask prints its count on the box; a jar you leave on overnight does not, so the figure is worked out from pack size at a typical application.

  • All 13 are free of drying alcohol and 11 of the 13 of essential oils - but only 6 are fragrance-free.

  • Butylene glycol is on 12 of the 13. Niacinamide is on 6 and squalane on 5, both at more than twice their share of the catalogue.

  • A median of €1.20 a night against €1.95 for a single sheet mask - though the first figure is estimated and the second is counted.

What these lists print that others do not

Not the most common ingredients - water is on nearly every list ever written and tells you nothing about a format. These are the entries that appear far more often here than across the 215 masks as a whole, counted by encyclopaedia entry rather than by printed name.

Well tolerated
No meaningful concern for most people; irritation is possible but rare.
Worth knowing
EU-restricted, a common contact allergen, or subject to live debate.
What the levels mean ↗

Names without a link have no encyclopaedia entry yet, so we make no claim about them beyond the count.

Cheapest use first. Every one is on sale in the EU and has a published ingredient list we could source and check.
