This toner contains CoQ10, Aloe Vera, and Hyaluronic Acid.  CoQ10 is a vitamin-like substance that is naturally found in every cell of the human body.  It is vital for proper cell function.  Aloe Vera, used for several thousand years for its therapeutic properties is beneficial to skin in different ways.  First, Aloe's polysaccharides act as moisturizers, hydrating the skin.  Secondly, Aloe is absorbed into the skin and stimulates the fibroblasts to replicate themselves faster, producing collagen and elastin, thus making the skin firm and supple.  An anti-inflammatory, Aloe is well known for its ability to heal wounds and speed up the healing process.
