ISOI's official product information presents Brightening Mask as a 20ml sheet-mask set built around the brand's brightening routine. The Olive Young option used for this candidate is a single sheet, so this guide keeps the comparison focused on one-use sheet-mask format and the product information that is publicly confirmed.
The direct answer
Compare this mask when you want a single-use sheet step with a brightening-focused routine cue. The tournament result reflects the choices you make between sheet-mask formats; it is not a clinical recommendation or a promise that one ingredient will suit every skin condition.
What is confirmed
ISOI's official product list names Brightening Mask as a 20ml × 10-sheet set and describes it as a sheet-mask version of the brand's brightening serum routine. The matching Olive Young option is listed as ISOI Brightening Mask 1ea. Those pack formats are recorded separately so a single-sheet comparison is not confused with a ten-sheet box.

What to compare before choosing
Compare the routine theme, the sheet format, and whether you want a one-off sheet or a multi-sheet box. If you avoid specific ingredients, check the current package ingredient list before use. Stop using a cosmetic if it causes irritation and seek professional advice when appropriate.
