numbuzin No.5 Brightening Sheet Mask — 5‑Pack with Glutathione & Vitamin C for Uneven Tone

numbuzin No.5 Sheet Mask is a vitamin-rich brightening sheet mask infused with glutathione and sprinkled vitamin C to help fade dark spots and refresh dull skin.

This single-use sheet mask blends antioxidant brighteners with hydrating actives to visibly even skin tone while delivering multi-layer moisture. Designed for quick at-home treatments, the formula mixes glutathione, vitamin C powder, niacinamide, hyaluronic acid and allantoin in a gentle base that finished clinical testing for tone improvement and low irritation. Each pack contains five masks for a short brightening course or maintenance routine.

How does this mask improve uneven skin tone and hyperpigmentation?

The mask combines glutathione and pure vitamin C powder with niacinamide to target visible discoloration and dullness. These ingredients work together to support a more uniform complexion and reduce the appearance of dark spots when used consistently.

• Glutathione and vitamin C help brighten and reduce pigment visibility.
• Niacinamide supports skin tone evening and texture refinement.
• Clinical testing reported measurable improvement in tone and dark spots after four weeks.

What hydrating and soothing benefits does the mask offer?

The formula delivers multi-layer hydration and calming support to avoid dryness or irritation while brightening. Hyaluronic acid and allantoin maintain moisture and soothe skin during treatment, making the mask suitable for sensitive types.

• Hyaluronic acid provides deep hydration and plumping effect.
• Allantoin helps calm and reduce surface redness.
• 11-layer moisture delivery from the sheet ensures skin feels replenished after use.

Is numbuzin No.5 safe for sensitive or acne-prone skin?

Yes — the product completed skin irritation testing and is formulated to be gentle for a range of skin types, including sensitive and acne-prone. It avoids harsh actives that commonly provoke irritation while still offering brightening performance.

• Clinically tested for low irritation on sensitive skin.
• Non-comedogenic formulation suitable for acne-prone complexions.
• Recommended application frequency supports gradual improvement without over-exfoliation.

How should I use the mask for best results?

Use the sheet mask as a 10–20 minute treatment one to three times weekly or as needed for brightening maintenance. For amplified effect, pair it with a tone-evening essence; clinical data shows combined use improved results versus essence alone.

• Cleanse and optionally apply a light essence before the mask.
• Place the sheet evenly over face for 10–20 minutes, then pat remaining serum into skin.
• Follow with moisturizer and sunscreen during daytime use.

Who is this for? numbuzin No.5 Sheet Mask is intended for anyone seeking a gentle brightening boost: people with hyperpigmentation, dark spots, post-acne marks, or dull complexion, and users with oily, dry, combination, sensitive, or acne-prone skin who want measurable tone improvement without aggressive irritation.
