Vitamin C Infusion

High-dose intravenous vitamin C (ascorbic acid) infusion delivering antioxidant support, immune enhancement, and skin brightening effects — with bioavailability significantly exceeding what oral supplementation can achieve.

Intravenous vitamin C infusion delivers high-dose ascorbic acid directly into the bloodstream, bypassing the intestinal absorption ceiling that limits oral vitamin C supplementation. At oral doses above approximately 1 g per day, vitamin C absorption becomes saturation-limited and excess is excreted renally; intravenous delivery achieves plasma concentrations 30 to 70 times higher than the maximum attainable orally, enabling pharmacological effects that are inaccessible through supplementation alone. At the cellular level, ascorbic acid functions as a primary aqueous-phase antioxidant, neutralising reactive oxygen species (free radicals) that damage cell membranes, DNA, and structural proteins. It is also an essential cofactor for collagen hydroxylation — the enzymatic step that makes procollagen chains stable enough to form mature collagen fibres. Without adequate vitamin C, fibroblasts produce less collagen and the existing collagen matrix becomes structurally fragile. High-dose IV delivery provides both the antioxidant protection and the enzymatic cofactor supply to maximally support dermal collagen production and integrity. For skin brightness, the anti-oxidant action of vitamin C inhibits the enzymatic oxidation steps in the melanin synthesis pathway (tyrosinase inhibition), reducing pigmentation in sun-damaged and uneven-toned skin over a course of treatments. Systemically, high-dose vitamin C supports immune function by enhancing neutrophil and lymphocyte activity, and has been studied in the context of reduced inflammatory cytokine production, fatigue, and recovery from illness. At Aesthetic Club Berlin, the vitamin C infusion is administered intravenously via a peripheral cannula over approximately 30 minutes. Patients typically notice improved skin clarity and a sense of increased energy over the 48 hours following the infusion. A course of four to eight weekly infusions is recommended for patients seeking skin brightening and anti-aging support, with monthly maintenance thereafter.
