Support Your Skin's Natural Defense

Glutathione is a potent antioxidant your body makes. This mask helps replenish what time and the environment deplete, optimizing your skin's own resilience.

1. **High-Concentration Glutathione Essence** — Each mask is infused with 23ml of essence containing a stabilized, high-purity form of Glutathione, a master antioxidant your skin recognizes and uses.

2. **Japanese GMP-Certified Manufacturing** — Produced in a facility adhering to Japan's strict Good Manufacturing Practice standards, the same rigorous protocols used for pharmaceuticals.

3. **Premium Fit Sheet Material** — Uses a specially developed, non-woven fiber sheet that holds 23ml of essence and conforms closely to facial contours for even absorption.

4. **pH-Balanced Formula** — Engineered to match skin's natural pH level to support the skin barrier and minimize potential for irritation.

5. **No Added Fragrance** — Formulated without artificial perfumes, as noted by users who prefer 'no smell' in their skincare.

6. **Dermatologist-Tested** — The final formula has undergone dermatological testing for skin compatibility.

7. **Stabilized Antioxidant Delivery** — The Glutathione in the essence is in a form specifically stabilized to remain potent and effective until you open the pouch.

8. **High-Essence Retention** — The sheet material is designed to prevent dripping while locked in the 23ml of treatment essence against the skin.

9. **Individually Sealed Packaging** — Each mask is factory-sealed in its own aluminum pouch to ensure sterility and preserve ingredient integrity.

10. **Made in Japan** — Final production, filling, and packaging occur entirely within Kose's certified facilities in Japan.

1. Cleanse and tone your face. 2. Unfold the mask from the pouch and apply it to your skin, aligning it with your eyes, nose, and mouth. 3. Leave on for 10-15 minutes (the 'sweet spot' noted by users). 4. Remove the mask and gently pat the remaining essence into your skin until fully absorbed. No need to rinse. For best results, use 2-3 times per week.

Timeline Expectations

- Week 1: Initial hydration and a refreshed, 'plumped' feel immediately after use. Skin may look less tired.

- Week 2-3: With consistent use, cumulative brightening effects become noticeable. Dullness starts to fade, and skin tone begins to look more even.

- Week 4+: Long-term radiance and clarity. The appearance of dark spots and post-acne marks can be visibly diminished, revealing a more luminous, translucent complexion.

Kose was founded in 1946 in Tokyo, Japan, with a simple mission: to create effective, no-nonsense skincare backed by real science. The Clear Turn Glutathione Bomb Mask was developed in their labs to directly address the dullness and uneven tone caused by modern stressors like pollution and blue light. Their researchers chose a high-concentration, stabilized form of Glutathione—a molecule your skin naturally produces but loses over time—because clinical data showed it was the most direct path to visible brightness. Every batch is produced in a Japanese GMP-certified facility, the same standard used for pharmaceuticals, ensuring purity and potency in every sheet. This commitment to proven ingredients and rigorous manufacturing has made it a top-ranked sheet mask in Japan for brightening, trusted by users who want results, not just promises.

The Kose Clear Turn Glutathione Bomb Mask - Brightening & Radiance (7 Sheets) features a carefully curated blend of ingredients designed to enhance skin luminosity and overall radiance. Central to its formulation is glutathione, a potent antioxidant that inhibits melanin production to reduce hyperpigmentation and promote a brighter, more even skin tone. This is complemented by niacinamide (vitamin B3), which works synergistically to improve skin barrier function, minimize pore appearance, and diminish redness, while also targeting dark spots for a clearer complexion. Hyaluronic acid is included for its exceptional hydrating properties, drawing moisture into the skin to plump and smooth fine lines, ensuring a supple and dewy finish. Additional components like glycerin provide sustained moisture retention, and botanical extracts such as licorice root offer soothing and anti-inflammatory benefits, helping to calm irritation and enhance skin clarity. Together, these ingredients deliver a multi-faceted approach to brightening, hydrating, and revitalizing the skin, making this mask an effective treatment for achieving a radiant and rejuvenated appearance.
