For quick and noticeable results, vitamin shots or IVs (intravenous drips) are much recommended by skin care experts. When paired with other treatments, these increase skin hydration, promote new collagen formation and enhance blood supply. The oxygen infusion also addresses dark circles and tired and brittle skin. You know those at-home masks that leave your skin feeling hydrated afterward? Well these shots do that but on a deeper level, so your face is immediately smoother and plumper.
