numbuzin Vitamin Spotlight No.5 Sheet Mask — 5-Pack Glutathione & Vitamin C for Brightening and Hydration

numbuzin No.5 Sheet Mask is a vitamin-forward sheet mask combining glutathione and real vitamin C powder to reduce dark spots and brighten dull skin with gentle hydration.

This lightweight sheet mask pairs antioxidant actives—glutathione, vitamin C, and niacinamide—with hydrating hyaluronic acid and soothing allantoin to support a more even, radiant complexion. Formulated for daily skin renewal, the mask delivers layered hydration and is clinically tested for tone improvement and reduced hyperpigmentation while being suitable for sensitive and acne-prone skin.

How does this mask help fade dark spots and uneven tone?

The formula targets pigment and discoloration using a trio of antioxidants and tone-brightening ingredients. Glutathione works alongside vitamin C and niacinamide to support a more uniform skin appearance, while clinical testing shows measurable improvement in tone and dark spots over four weeks.

• Glutathione and vitamin C work together to address areas of hyperpigmentation.
• Niacinamide complements by reducing the appearance of uneven tone and strengthening barrier function.
• Clinical results: tone improved by 12.79% and dark spots reduced by 17.34% in four weeks.

What kind of hydration and soothing benefits does it provide?

numbuzin No.5 delivers multi-layer hydration and calming support to help revive tired or dry skin. The sheet is formulated to provide eleven layers of moisturizing effect while hyaluronic acid and allantoin help replenish moisture and reduce surface irritation.

• Hyaluronic acid attracts and holds moisture for plumper-feeling skin.
• Allantoin soothes and calms redness or sensitivity after application.
• The sheet material is designed to fit closely for efficient ingredient absorption.

Is this sheet mask safe for sensitive or acne-prone skin?

Safety testing indicates the mask is non-irritating and suitable for a wide range of skin types, including sensitive and acne-prone skin. The formulation avoids harsh actives that provoke inflammation while retaining effective antioxidant and tone-evening components.

• Completed skin irritation tests support gentle use for sensitive skin.
• Free from aggressive exfoliants that could trigger breakouts.
• Recommended for oily, dry, combination, acne-prone, and sensitive skin types.

How should I use numbuzin No.5 for best results?

Use the sheet mask as part of your regular skincare routine—ideally 2–3 times weekly or as needed for targeted brightening. For enhanced effectiveness, apply after cleansing and toning; pairing with a tone-evening essence increased effectiveness in trials.

• Cleanse and tone, then place the sheet for 10–20 minutes.
• Gently pat remaining serum into skin; do not rinse off.
• Combine with a compatible essence to boost overall brightening results.

Who is this for? numbuzin No.5 is designed for anyone looking to reduce the appearance of dark spots, acne marks, or a dull complexion without aggressive ingredients.
