Glutathione (abbreviated GSH) is the most powerful antioxidant naturally produced by the human body — a tripeptide composed of three amino acids: glutamine, cysteine and glycine. Produced primarily in the liver, it is found in every cell of the body and plays a central role in neutralising free radicals, detoxifying environmental toxins and heavy metals, supporting immune function and protecting cells from oxidative damage. It is called the "master antioxidant" because it also regenerates other antioxidants — including Vitamins C and E — back to their active forms after they have been oxidised. For skin brightening, glutathione works through a biochemically established mechanism: it inhibits tyrosinase — the rate-limiting enzyme that converts the amino acid tyrosine into melanin (the pigment responsible for skin colour and dark patches). By inhibiting tyrosinase activity, glutathione shifts the balance of melanin production from darker eumelanin (brown-black pigment) toward lighter pheomelanin (yellow-red pigment). This melanin shift produces a progressive brightening of skin tone, fading of hyperpigmentation and dark spots, and an improvement in overall skin evenness and radiance that becomes more significant over a consistent course of IV sessions. As a free radical scavenger, glutathione also reduces the oxidative damage to melanocytes that perpetuates pigmentation overproduction — meaning it addresses both the symptoms and a key underlying driver of pigmentation simultaneously.

A course of 6 to 10 sessions spaced 1 to 2 weeks apart is typically recommended for complete, clinically meaningful skin brightening results. Results are progressive and build cumulatively with each session — glutathione is not an instant treatment, and results require consistent, patient adherence to the recommended course. Most clients notice an initial improvement in skin radiance and a subtle "glow" from sessions 2–4 (within the first 2–4 weeks). Measurable, visible lightening of overall skin tone and a noticeable reduction in pigmented areas typically becomes apparent between 6–8 weeks of consistent treatment. Full, optimal brightening results — including significant fading of dark spots, melasma and overall tone improvement — are generally seen at 2–3 months after completing the recommended course. The exact number of sessions and the timeline to visible results depend on several factors: your starting skin tone and degree of pigmentation, the specific formulation and glutathione dose used, your lifestyle (particularly sun exposure habits), dietary antioxidant intake and how consistently you follow the SPF protocol between sessions. Your dermatologist will assess your response at each session and adjust the plan accordingly. After completing the initial course, maintenance sessions every 4–6 weeks are recommended to sustain and build on the results achieved.

IV glutathione treatment, when administered by a certified dermatologist using clinically approved pharmaceutical-grade formulations at appropriate dosages, is considered safe for Indian skin and has a good safety profile in published clinical literature. The key factors determining safety are: (1) a thorough pre-treatment medical assessment to screen for contraindications (kidney disease, asthma, pregnancy, specific medications); (2) the use of clinically approved, pharmaceutical-grade glutathione formulations rather than unregulated or unlicensed products; (3) appropriate dosing matched to your health profile; (4) administration by qualified medical personnel with full monitoring during infusion. The primary safety concern associated with glutathione use in non-clinical, non-supervised settings is the use of unapproved, unlicensed or very high-dose formulations — which carry real risks of kidney damage, thyroid disruption, nerve damage and dermatological complications. This is precisely why dermatologist supervision, appropriate formulations and pre-treatment medical screening are non-negotiable at Maynee. When these clinical standards are followed, the risk profile for IV glutathione at therapeutic skin brightening doses is low for the vast majority of healthy adults. Your dermatologist will discuss your individual risk profile fully at your skin assessment before any treatment is recommended.

The fundamental difference is bioavailability — the amount of glutathione your body actually absorbs and can use — and this difference is clinically significant. IV glutathione is delivered directly into the bloodstream via an intravenous infusion, bypassing the digestive system entirely. This achieves close to 100% bioavailability — meaning virtually all of the therapeutic dose of glutathione reaches systemic circulation, where it can act on melanocytes, skin cells, the liver and immune system at the concentrations needed to produce visible brightening results. Oral glutathione supplements — taken as capsules, tablets or sublingual drops — must pass through the digestive system and undergo first-pass metabolism in the liver before any reaches systemic circulation. A significant proportion of oral glutathione is broken down into its constituent amino acids during digestion, reducing the amount that reaches the bloodstream as intact, active glutathione. Current estimates place oral glutathione bioavailability at approximately 30–50% at best, and the therapeutic plasma concentrations achievable with oral supplements are considerably lower than those achieved with IV administration. For meaningful, visible skin brightening results within a reasonable timeframe, IV glutathione is the clinically preferred and most evidence-backed delivery route. Oral glutathione supplements can serve as a useful adjunct — to maintain glutathione levels between IV sessions — but are generally insufficient alone for significant visible skin brightening in adults with established pigmentation or uneven tone.

Glutathione treatment via IV infusion is minimally uncomfortable. The only needle sensation in the entire session is the brief, mild pinch of the IV cannula insertion into a vein in the forearm — comparable to a standard blood test needle. Once the cannula is placed and secured, the infusion itself is completely painless. Most clients describe the experience as comfortable and relaxing — comparable to sitting quietly and reading while an IV line drips — and many use the 30–45 minute session to read, browse their phone or simply rest. Some clients occasionally notice a mild warmth or flushing sensation during infusion as the glutathione circulates — this is a harmless and normal physiological response that resolves on its own. A small number of clients may notice a brief, transient garlic-like odour on their breath or skin during infusion — this is a known and expected phenomenon related to the sulphur-containing cysteine component of glutathione and resolves completely after the session. Our clinical team is present throughout the session and monitors for your comfort. The cannula is removed at the end of the session with no additional discomfort. Clients can return to normal activities immediately.

When administered by a certified dermatologist using clinically approved formulations at appropriate therapeutic dosages, IV glutathione is generally well-tolerated with a low incidence of side effects. Mild, occasional side effects can include temporary nausea or mild stomach discomfort during or shortly after the infusion; brief dizziness or lightheadedness (usually position-related and resolving quickly); and the transient garlic-like breath or body odour described above. These are generally mild, self-limiting and resolve without intervention. Rarer side effects can include skin rash or urticaria (hives) in individuals with undisclosed sensitivities to formulation components — which is why our clinical team monitors you throughout every session and why a thorough pre-treatment allergy and medical history review is conducted before the first session. The most significant risks associated with glutathione treatment arise from non-supervised, non-clinical use — particularly the use of unregulated, high-dose or unlicensed formulations available outside medical settings. These formulations can cause kidney damage, thyroid dysfunction, nerve damage (reported at very high doses) and Stevens-Johnson syndrome (a rare but severe skin reaction). At Maynee, clinical standards, pharmaceutical-grade approved formulations, appropriate dosing and full dermatologist supervision ensure that these serious risks remain in the domain of non-medical, non-supervised use — not clinical dermatologist-administered treatment. All relevant side effects and your individual risk profile are discussed openly at your pre-treatment consultation.

Glutathione treatment produces significant, progressive skin brightening that is real and measurable — but it is important to understand that the results are not permanent in the way that, for example, a surgical procedure might be. Glutathione works by inhibiting tyrosinase and suppressing melanin production while treatment is ongoing. Once a course of treatment is completed and no maintenance sessions are continued, the tyrosinase-inhibiting effect gradually diminishes and the body's natural melanin production gradually resumes — meaning skin tone may gradually return toward the individual's natural genetic baseline over time, particularly with continued UV exposure. This means that sustaining the brightening results achieved requires a maintenance plan — typically periodic IV glutathione sessions every 4–6 weeks, continued strict daily SPF use, an antioxidant-supportive diet and avoiding excessive sun exposure. Clients who maintain this protocol consistently report sustained results over many months and years. It is also important to have clinically honest expectations: glutathione treatment brightens your skin progressively — it does not instantly or dramatically alter your fundamental genetic skin tone in a single course. Results build gradually over sessions, and the degree of brightening achievable varies between individuals. Your dermatologist will set clear, realistic expectations for your specific skin type and concern at your consultation.

Yes — glutathione treatment is clinically recognised for improving pigmentation, dark spots, post-inflammatory hyperpigmentation and melasma, and is one of the most commonly used adjunctive treatments for these concerns in Indian dermatology. For pigmentation and dark spots (whether from sun exposure, post-acne marks or age), glutathione's tyrosinase-inhibiting action progressively blocks the ongoing melanin overproduction in hyperactive melanocytes, while natural skin cell turnover sheds existing pigmented cells over the treatment course — producing measurable fading of established dark areas. For melasma — which is a chronic, hormonally-driven condition with a multifactorial basis — glutathione is most effective as part of a comprehensive, multi-modal protocol that also includes dermatologist-prescribed topical brightening agents (niacinamide, kojic acid, azelaic acid or hydroquinone as appropriate), strict broad-spectrum SPF compliance and hormonal management where relevant. Glutathione alone is typically insufficient to fully control significant melasma in isolation — but as part of a properly designed combination approach, it contributes meaningfully to improved melasma control and sustained MASI score reductions. Your dermatologist will assess the type, depth and severity of your pigmentation and design the most appropriate protocol — whether glutathione alone or glutathione combined with other clinical interventions such as glycolic acid peels — for your specific case.

Before each session: Drink at least 2 litres of water on the day of your appointment — good hydration supports comfortable vascular access and optimises the infusion experience. Eat a light, nutritious meal before your appointment — do not arrive fasted or with low blood sugar. Avoid alcohol for at least 24 hours before treatment (alcohol depletes glutathione in the liver). Inform your dermatologist of any new medications, supplements, vitamins, herbal remedies or health changes since your last session. Avoid blood-thinning medications (aspirin, NSAIDs, high-dose fish oil) without medical guidance in the 24 hours before. Defer the session if you have an active infection, fever, significant illness or any new health concerns.

After each session: Apply SPF 30+ broad-spectrum sunscreen every day — and reapply every 2–3 hours outdoors. This is the single most important action you can take to maximise your brightening results. UV exposure between sessions directly stimulates the melanin production that glutathione is working to suppress — effectively counteracting your treatment progress. Maintain an antioxidant-rich diet: Vitamin C-rich foods (citrus, guava, amla, berries) support glutathione recycling in tissues and amplify the between-session benefit. Stay well-hydrated. Avoid smoking (depletes glutathione rapidly) and limit alcohol. Take prescribed oral glutathione supplements and topical brightening agents as directed between sessions. Avoid heavy exercise for 4–6 hours post-infusion. Contact your dermatologist if you notice any unusual symptoms such as skin rash, hives, difficulty breathing or prolonged nausea after the infusion.

Glutathione treatment cost at Maynee in Chennai depends on several factors: the specific glutathione formulation and dosage selected for your skin type and goals (concentration range varies from 600mg to 2400mg per session), the number of sessions in your recommended course (typically 6–10 for full results), whether Vitamin C co-infusion and other adjunctive supplements are included, and whether complementary treatments such as glycolic acid peels or microneedling are recommended as part of a combination protocol for your specific concern.
