moisture mask

Recommended frequency varies by product: some hair and scalp masks note daily or weekly use, many hair treatments suggest once a week (or more), and single-use foot masks are clinical or one-time treatments.

Leave-on time depends on the mask type: many hair masks recommend about 1–20 minutes, face hydrogel sheet masks typically advise 15–30 minutes, and single-use foot masks are often worn for about 10 minutes.

Many masks include cruelty-free or not-tested-on-animals statements; several are labeled vegan, and some use “plant-based” wording or PETA-related animal-test-free language.
