It is an advanced, direct-acting oil-like serum that helps visibly reduce signs of aging by brightening and balancing uneven skin tone. Gives a small molecular size, allowing for faster visible results with less irritation potential. Ethylation is a process that helps promote the stability of Vitamin C while still retaining the direct-acting benefits when compared to other Vitamin C Derivatives. And because it has advanced antioxidant properties, this water free formula protects your skin from the visual effects of damage caused by environmental stressors, helping to maintain a more radiant complexion.
