TOSOWOONG Glutathione Ampoule Serum 30ml

A high-purity brightening serum with 20,000ppm Glutathione, Niacinamide, and 5 types of Hyaluronic Acid - fades dark spots, adds antioxidant glow, and hydrates in one lightweight step.

99% purity Glutathione at 20,000ppm - most glutathione serums use lower concentrations with undisclosed purity. Combined with Niacinamide and Adenosine, this ampoule works as both a brightening treatment and anti-aging serum in one step. Irritation index 0.0 - safe for all skin types.

What it does

Brightens and fades dark spots with Glutathione
Glutathione at 99% purity and 20,000ppm suppresses melanin production and neutralizes free radicals that trigger oxidative skin aging - delivering a visible glow effect and gradual fading of dark spots, sun damage, and uneven tone.
Evens tone and refines pores with Niacinamide
Niacinamide blocks melanin transfer between skin cells, strengthens the skin barrier, and visibly reduces pore size and redness - amplifying the brightening effect of Glutathione for a more even, refined complexion.
5 types of Hyaluronic Acid for multi-depth hydration
Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Sodium Hyaluronate Crosspolymer, Hyaluronic Acid, and Hydrolyzed Sodium Hyaluronate target different skin depths - keeping skin continuously plump and smooth without any heavy or sticky residue.
Anti-aging support with Adenosine and botanicals
Adenosine supports collagen production and tissue repair to visibly smooth crow's feet, smile lines, and forehead wrinkles. Rose water, vanilla, apple, and strawberry extracts add antioxidant protection and a light, pleasant natural scent.

How to use

  1. After cleansing and toning, apply an appropriate amount evenly over the face.
  2. Gently press and pat into skin until fully absorbed.
  3. Follow with moisturizer. Use morning and night for best results.

The natural scent of this serum comes from high-concentration Glutathione itself - no artificial fragrances are added. Perform a patch test before first use if you have reactive skin.

Quick FAQs

What does Glutathione do for skin?
Glutathione is a naturally occurring antioxidant that suppresses melanin production and neutralizes free radicals that accelerate skin aging. At high concentrations it visibly brightens overall skin tone, fades dark spots, and adds a healthy, lit-from-within glow over consistent use.
Why does it have a natural scent?
The mild scent is a natural characteristic of high-concentration Glutathione - no artificial fragrances are used. The scent is not detectable once the serum has absorbed into skin.
How is this different from the TOSOWOONG Arbutin or TXA products?
Glutathione brightens by neutralizing oxidative damage and suppressing melanin at a systemic level, making it an excellent complement to Arbutin and TXA which work by directly inhibiting melanin enzymes. Using this ampoule under the Arbutin or TXA cream creates a more comprehensive brightening routine.
