Thanks for the query. The evidence for a strong robust support for usage of glutathione injection is not convincing, however oral formulations can be tried. This is a off label practice and depends on the experience and comfort of the treating physician.A good skin care regimen comprises 4 steps - cleansing, toning, moisturizing and sunblock. Based on your skin type, a dermatologist will recommend you appropriate products. Combining treatment modalities will be helpful and glutathione alone will disappoint you.
