How to use
Using your L-Gutathione Pen is quick, simple, and virtually painless:
- Prepare – Wash your hands thoroughly and open your kit. Allow the L-Glutathione cartridge to reach room temperature for comfort.
- Assemble – Insert the cartridge into the pen, attach a micro-needle, and prime the device.
- Select Injection Site – Choose a fatty area such as the stomach, buttocks, or thigh. Clean the area with an alcohol wipe.

- Dispose & Store – Remove the used needle, dispose of it in the sharps bin, and store the pen and any L-Glutathione cartidges in the refrigerator.
Best Dose Schedule?
We recommend 1 dose per day for the 3 days followed by every alternate day thereafter. This will ensure you get the required initial boost to your L-Glutathione levels and then enter a maintenance schedule.
However, we do also encourage you to find a protocol that suits your lifestyle. It can be taken once a day, once a week, or even as and when you feel it is needed.

Ingredients (INCI)
L-Glutathione
The benefits of NAD+
Glutathione is the body's master antioxidant, made in every cell. Levels fall with age, stress and sun, so replenishing it supports how your skin looks and how you feel.
Brighter, even skin
Helps soften dullness and even skin tone by targeting excess melanin production.
Whole-body detox
Binds to toxins and supports the liver's natural detoxification pathways.
Master antioxidant
The body's most powerful antioxidant, defending cells against oxidative stress.
Immune support
Supports immune resilience and healthy, energised cellular function.
Brightens and evens skin tone
Helps reduce the appearance of dullness and uneven pigmentation by influencing melanin production. This is why it’s often linked to brighter-looking skin.
Powerful antioxidant protection
Neutralises free radicals caused by UV exposure, pollution, and stress, helping protect skin from premature ageing.
Supports detox processes
Works in the liver and cells to help remove toxins and oxidative stress, which indirectly supports clearer, healthier-looking skin.
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+
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.
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.
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
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.
