Glow Plus IV

A 45-minute beauty-focused IV infusion combining high-dose glutathione with vitamin C and biotin to support skin radiance, collagen production, and antioxidant defence from within.

The Glow Plus IV is The Retreat's beauty-focused intravenous therapy, built around glutathione — the body's most powerful endogenous antioxidant. Glutathione plays a central role in neutralising free radicals, supporting liver detoxification, and modulating melanin production. When administered intravenously at therapeutic doses, it produces a measurable brightening effect on the skin by inhibiting tyrosinase, the enzyme responsible for melanin synthesis. The formulation pairs glutathione with high-dose vitamin C (a cofactor in collagen synthesis and itself a potent antioxidant) and biotin (vitamin B7, which supports keratin infrastructure in skin, hair, and nails). This combination addresses skin health from multiple pathways: antioxidant protection against UV and pollution damage, structural support for collagen and elastin networks, and improved cellular turnover. Oral glutathione supplementation is notoriously inefficient — the tripeptide is broken down in the gut before reaching systemic circulation, with bioavailability estimates as low as 5-10%. Intravenous delivery bypasses this limitation entirely, achieving plasma concentrations that oral supplementation cannot match. This is why IV glutathione has become a cornerstone of aesthetic medicine protocols worldwide. The 45-minute infusion is administered in The Retreat's comfortable clinical setting with full medical oversight. Results are cumulative — while some clients notice improved skin luminosity after a single session, optimal results typically emerge after 4-6 weekly sessions. The Glow Plus IV is often combined with red light therapy for synergistic skin-rejuvenation benefits.
