Pack of 2 - Hyaluronic acid is a superstar in the field of youth extension. Why? Researchers found it can firm your skin, reduce fine lines, smooth wrinkles, and improve skin disorders. It lubricates joints to keep a spring in your step. It improves vision and dry eyes. It aids connective tissue problems like arthritis, tmj, torn ligaments, as well as hernia and mitral valve prolapse. what's important is picking the right form of hyaluronic acid. There are three forms on the market, and neocell offers only the natural, most bio-available form. The gold standard is pure hyaluronic acid carefully sourced from external tissue, rooster comb. It costs 10-20x more, but your body recognizes this form as ha and absorbs it more completely than alternatives sourced from bone and mixed with collagen, or than the lab-created sodium hyaluronate. Neocell recommends supplementing both super collagen peptides and ha together as they work synergistically to enhance radiant skin, hair and a youthful body. in the body, collagen and ha are almost always found together; collagen provides the mechanical strength for connective tissues and ha, with its ability to bind enormous amounts of water, serves to lubricate these same tissues providing necessary hydration.
