Description

L-Glutathione is known as the body’s “master antioxidant”  a naturally occurring tripeptide composed of cysteine, glycine, and glutamic acid. It is found in every cell and is crucial for protecting against oxidative stress, supporting immune defence, and maintaining youthful, radiant skin. However, natural glutathione levels decline with age, environmental toxins, stress, alcohol, and poor diet.

Our L-Glutathione 1800mg Home Injection Kit offers an advanced subcutaneous delivery method that bypasses the digestive tract, ensuring near-100% bioavailability and rapid cellular uptake. This allows glutathione to work at the deepest cellular level, enhancing detoxification, reducing inflammation, improving complexion, and supporting liver and immune health.

Key Benefits:

  • Brightens and evens skin tone by inhibiting melanin formation
  • Neutralises free radicals and oxidative stress for anti-ageing protection
  • Detoxifies the liver and supports optimal metabolic function
  • Improves immune resilience and overall cellular defence
  • Reduces the appearance of dark spots, pigmentation, and sun damage
  • Enhances skin radiance, elasticity, and hydration from within
  • Promotes recovery and protects against fatigue and stress
  • Clinically formulated for high purity and fast absorption
How Does It Brighten Skin?

Glutathione supports visible skin clarity through two scientifically recognised mechanisms:

  • Inhibition of Tyrosinase: Glutathione suppresses the activity of the tyrosinase enzyme, which is essential for melanin synthesis. This process shifts melanin production from eumelanin (darker pigment) to pheomelanin (lighter pigment), resulting in a brighter, more even complexion.
  • Antioxidant Defence: By reducing oxidative stress, glutathione prevents the activation of melanocytes triggered by free radicals, reducing dark spots and pigmentation caused by UV exposure or inflammation.

Clinical studies have shown that regular glutathione supplementation can result in visible brightening and improved skin elasticity within 4–8 weeks, depending on dosage and frequency.

THE RITUAL

A few quiet minutes, on your schedule

No clinic, no appointments. Each kit comes with everything you need for a hygienic at-home routine, plus a step-by-step guide. Refrigerate on arrival, rotate sites, and let your skin and body do the rest.

The science of NAD+

The science explained

Glutathione is a tripeptide made from three amino acids and is the body's master antioxidant, found in every living cell. Levels fall with age, stress, sun exposure and modern life, which can show up as dullness, uneven tone and low energy.

Replenishing glutathione supports brighter, clearer skin, natural detoxification and immune defence. Delivered subcutaneously, it bypasses the digestive system for high bioavailability, so your cells can put it to work quickly.

Scientific insight
Glutathione neutralises free radicals and recycles other antioxidants such as vitamins C and E. It also helps regulate tyrosinase, the enzyme behind melanin production, which is why it is prized for a brighter, more even complexion.

WHY SUBCUTANEOUS

High bioavailability, visible results

Oral glutathione is largely broken down in digestion. Delivered subcutaneously, it reaches your system directly, so more of the active goes to work on brightness, detox and antioxidant defence.

Your questions answered

Your questions answered
What does glutathione do?

Glutathione is the body's master antioxidant. It supports brighter, more even skin, natural detoxification and immune defence by neutralising free radicals and helping regulate melanin production.

How soon will I see results?

Many people notice a brighter, fresher complexion and more energy within a few weeks. Glutathione works best taken consistently across the full protocol.

How often should I use it?

Follow the protocol in your kit, typically a small subcutaneous dose two to three times a week. Each vial provides multiple doses.

Why injection instead of a capsule?

Oral glutathione is largely broken down in digestion. Subcutaneous delivery bypasses the gut for much higher bioavailability, so more of the active reaches your cells.

Will the injection hurt?

It can sting slightly and small bruises are not unusual. Take the vial out of the fridge about 30 minutes beforehand, insert at a 45 degree angle just under the skin, and rotate sites each time.

Where is best to inject?

Subcutaneously, just under the skin into fatty tissue. The stomach, hips or buttocks work well. Rotate the site with each dose.

Who is glutathione not suitable for?

Not suitable for anyone under 18, or with an allergy to glutathione or sterile solutions. Please speak to your doctor first if you are pregnant or breastfeeding, or have a serious health condition.

Are there any side effects?

Most people notice none. Occasionally there can be mild sensitivity at the injection site. If that happens, choose a different site next time, and stop if anything feels unusual.

How should I store it?

Refrigerate the vial for optimal freshness. It also stays stable at room temperature for a short period, so a day in transit is no problem.

How is it delivered?

Discreetly and tracked across the UK, packed with a cool pack to keep it in perfect condition. A Certificate of Analysis is available on request.
