High-Performance Glutathione Brightening Ampoule for Microneedling

Medisco MesO Glutathione is a professional-grade brightening ampoule formulated to help maximise the visible results of microneedling treatments. 

At the heart of Medisco MesO Glutathione is a concentrated dose of Glutathione, a powerful antioxidant valued for helping support the look of a more even skin tone, radiance and overall skin resilience. This professional-grade Korean brightening ampoule is formulated to help maximise the visible results of microneedling treatments and support a clearer-looking complexion, designed specifically for use alongside microneedling protocols.

The lightweight, fast-absorbing formula helps defend against environmental stressors while helping target the appearance of dullness and uneven-looking skin tone. When used with microneedling, absorption is significantly enhanced, helping support more noticeable brightening and a smoother, more refined-looking complexion.
