Glutathione Brightening Treatment (often nicknamed the “IU shot”)

What is glutathione?

Glutathione is a powerful antioxidant naturally abundant in the liver, kidneys, and brain. It helps neutralize reactive oxygen species (ROS), reduces cellular damage, and regenerates other antioxidants such as vitamins C and E—supporting healthy aging and cellular protection.

How glutathione supports a brighter, more even skin tone

• 
  
• 
  
• Tyrosinase inhibition: Helps suppress the enzyme (tyrosinase) that drives excess melanin production.
• 
  
• 
  
• 
  
• Melanin pathway shift: Encourages a shift from darker eumelanin toward lighter pheomelanin for a clearer-looking complexion.
• 
  
• 
  
• 
  
• Antioxidant protection: By removing ROS generated by UV, heat, or inflammation, glutathione helps curb the signals that trigger new pigment.
• 
  
• 
  
• 
  
• Synergy with vitamin C: Vitamin C helps recycle oxidized glutathione, while glutathione further limits melanin synthesis—creating a strong “brightening network.”
• 
  
• 
  

In short: Glutathione both reduces excess melanin formation and nudges pigment toward lighter pathways, promoting a naturally brighter, more even tone.

Why choose KKEUT Clinic for glutathione care?

Many people try oral supplements or IV drips, but each has limitations.

Limits of common approaches

• 
  
• 
  
• Oral (pills): Low and variable absorption in the gut; most is metabolized in the liver, so little reaches the skin.
• 
  
• 
  
• 
  
• IV drips: Circulates system-wide, which can help overall antioxidant status but is not targeted to facial pigmentation or tone.
• 
  
• 
  

Our targeted approach

• 
  
• 
  
• Iontophoresis delivery: We use a gentle electrical current to drive glutathione across the skin barrier directly toward the dermis—combining the “directness” of in-clinic care with the targeting pills and IVs lack.
• 
  
• 
  
• 
  
• Area-focused absorption: Instead of distributing it throughout the whole body, we concentrate delivery where tone and pigmentation need help—your facial skin.
• 
  
• 
  
• 
  
• Full-strength ampoules: We use undiluted, full-strength glutathione ampoules to maximize antioxidant and brightening benefits.
• 
  
• 
  

Our philosophy: “More direct than oral, more targeted than IV.”

Why iontophoresis?

• 
  
• 
  
• Overcomes oral limits: Avoids inconsistent GI absorption and first-pass liver metabolism.
• 
  
• 
  
• 
  
• Beats simple topical application: The outermost skin layer (stratum corneum) blocks many water-soluble ingredients like glutathione.
• 
  
• 
  
• 
  
• How it works
• 
  
• 
  
• 
  
• Electromigration (electric repulsion): Uses a mild current to push negatively charged glutathione molecules through the skin barrier.
• 
  
• 
  
• 
  
• Electro-osmosis: Creates a micro-flow that widens the path for ingredient transport.
• 
  
• 
  
• 
  
• Deeper reach: Delivers active ingredients closer to the dermal layer, beyond where ordinary creams can act.
• 
  
• 
  
• 
  
• 
  

Bottom line: Iontophoresis is absorbed more directly than oral and deeper than simple topical application.

Treatment plan
