Your skin absorbs more vitamin C than your stomach

Since 1932, when the Nobel Prize was awarded for discovering that vitamin C cures scurvy, we have known that the body needs only a tiny amount to survive. However, the human gut acts as a strict gatekeeper, capped by a biological ceiling that prevents high doses from ever reaching the skin. By applying a stabilized form of the vitamin directly to the face, you can bypass this digestive limit and deliver roughly 200 milligrams per gram of tissue.
