What Do Vibriance Super C Serum Reviews Really Show?

How Vibriance's concentrate actually works on skin

Most vitamin C serums are built on a water base, because water is cheap and vitamin C dissolves into it easily enough to put on a label. The catch is that vitamin C oxidizes fast once it's diluted that way, which is why a lot of serums turn faintly orange in the bottle and stop doing much of anything within weeks. Vibriance's answer is to skip the water base entirely and build the serum on an evaporated lemon concentrate instead, so the vitamin C has less to be diluted into and, in theory, more of it survives to reach your skin. Layered onto that is what the brand calls an active lock delivery system, meant to hold the actives in the upper layers of skin rather than letting them sink and disappear, so the serum keeps working as a slow-release reservoir instead of a one-time hit that's gone in an hour. That's the actual reason one drop is supposed to be enough: not magic, just less water for the drop to compete with. It's also why the formula is positioned as gentle enough for the eye area, since a concentrate designed to sit at the surface doesn't need harsh penetration enhancers to get vitamin C where it's going. For your day, that means a serum meant to sit quietly under makeup rather than pilling on top of it, and one bottle doing the job of a separate hydrator, brightener and firming serum, if the concentrate holds up the way the base ingredient suggests it should.
