Questions about MEDICUBE Deep Vita C Glutathione Brightening Mask

Got questions? We’ve got answers!

Q1: Will it lighten my skin?

No. Brightening in this context means a fresher, less dull-looking complexion. It does not lighten skin tone or treat pigmentation.

Q2: What does glutathione do?

It is an antioxidant, widely used in Korean skincare in products aimed at dullness. In a cosmetic sheet mask it works on how skin looks rather than on pigment production.

Q3: Do I need sunscreen with it?

Wear a broad spectrum sunscreen daily, which is sensible with any vitamin C product and good practice regardless.

Q4: Is it fragranced?

No. The formula is fragrance free.

Q5: How long should I leave it on?

10 to 20 minutes. Leaving a sheet mask on after it starts to dry can pull moisture back out of the skin, though this sheet is designed to resist that.
