Description

Quality First Derma Laser Super Glutathione 100 Mask is a brightening Japanese sheet mask built around stabilized glutathione — an antioxidant-based brightening ingredient widely popular in Southeast Asia and South Asian skincare — combined with five types of vitamin C and niacinamide for an all-around luminosity and skin-clarity treatment. A Japan-domestic formula sold at Matsumotokiyoshi and major Japanese drugstores.

Glutathione is a notoriously unstable molecule that degrades quickly in conventional formulas. Quality First stabilizes it at high concentration using their nanocapsule delivery system, which penetrates to the stratum corneum in three minutes and allows the ingredient to work without oxidizing. The five vitamin C types and niacinamide in the formula actively support the glutathione's brightening effect.

Users on LIPS and @cosme describe the mask serum as rich and viscous with a notably dense moisture finish. Preservative-free, alcohol-free, fragrance-free.

Key Ingredients
  • Glutathione — stabilized antioxidant brightening ingredient that suppresses excess melanin and promotes an even, luminous complexion
  • 5-Type Vitamin C Complex — five vitamin C variants with different absorption speeds deliver sustained brightening action throughout the day
  • Niacinamide — inhibits melanin transfer, softens dark spots and supports overall skin clarity
  • Ceramide NP — moisture barrier reinforcement for hydrated, plump skin
  • Arbutin — additional brightening agent that works synergistically with glutathione and vitamin C to suppress discoloration

HOW TO USE
  1. After cleansing and toning, remove the mask from its pouch.
  2. Align to eye area first, then mouth, then smooth the sheet across the full face.
  3. Leave on for approximately 3 minutes, then remove and gently pat in remaining serum — the serum content is generous, use the remainder as a neck or décolleté treatment.
  4. Follow with moisturizer.
  5. Pro tip: Use 3–4 times per week for cumulative brightening results — users report noticeable luminosity improvement after consistent use over two weeks.

FAQ

What does glutathione do for skin?

Glutathione is an antioxidant that suppresses melanin synthesis by inhibiting tyrosinase activity. It promotes a brighter, more even skin tone and is particularly well regarded in Southeast Asian and South Asian skincare cultures for achieving a luminous, glass-skin effect.

Why is stabilized glutathione significant?

Glutathione oxidizes and loses potency quickly in conventional formulas. Quality First stabilizes it at high concentration using their nanocapsule system, which encapsulates the ingredient and releases it upon contact with skin — preserving its brightening efficacy.

How does this compare to the VC100 White mask?

Both target brightening and dullness. The VC100 White focuses on vitamin C-driven clarity and even tone. The Glutathione 100 adds stabilized glutathione for a deeper, antioxidant-based brightening approach and is often favored for more pronounced discoloration or those who have already tried vitamin C-only products.

Is this the Japan-domestic version?

Yes. TokyoShelf sources this directly from Matsumotokiyoshi and major Japanese pharmacies. This is the Japan-domestic formula, not an export version.
