Ingredients by volume

Plain old water
One of the few well researched potent anti-aging ingredients. When it is able to penetrate the skin in an active state, it is effective against fine lines and wrinkles, helps improve skin elasticity and reduce hyperpigmentation. It acts as a powerful anti-oxidant and stimulates collagen production. The main issue with ascorbic acid is that it is highly unstable, in other words, it is losing its effectivenss quickly when exposed to air and light (if a serum or cream containing ascorbic acid has an orange color, it is a likely that the ingredient has oxidized and is no longer active). In addition, it is water-soluble, meaning that it has difficulty pentrating the skin. It is also quite irritating, and can cause stinging. When used in low concentrations, helps stabilize the product formulation
