Cobamamide

Cobamamide is a form of vitamin B12 (cobalamin) used in skincare formulations. It functions as a skin conditioning and protective agent, with recognised antioxidant properties. The ingredient is derived from cobalamin chemistry and is incorporated into products to support skin health at a cellular level.In topical skincare, cobamamide is thought to work by reinforcing the skin's natural protective mechanisms and helping to counteract oxidative stress, which accumulates from environmental exposure and normal metabolic processes.

Cobamamide exerts its effects through its cobalamin structure, which can donate electrons to neutralise unstable free radical molecules. This antioxidant action helps reduce oxidative damage at the cellular level, which is implicated in skin ageing and inflammation.The ingredient also appears to support skin conditioning by enhancing the skin's natural hydration and resilience, though the precise mechanisms in topical application remain an area of ongoing research.

Cobamamide is typically used as a supportive ingredient within broader skincare routines. It is generally well-tolerated across formulation types and can be incorporated into serums, moisturisers and treatment products. Apply as directed by the specific product instructions. There is no need for special timing or sequencing with other ingredients, though it may be combined with other antioxidants for complementary protection.

Cobamamide is generally well-tolerated and does not have a known sensitising profile. It is suitable for use across all skin types, including sensitive skin.
