How do the PHAs and Bionic Acids function as anti-oxidants?
The PHAs/Bionic Acids chelate or trap oxidation-promoting metals in skin. They also help protect cell lipids and membranes from UV damage and help to preserve the skin’s natural elasticity by preventing an increase in the enzyme elastase. Finally, PHAs/Bionic Acids inhibit MMP enzymes in skin, which are responsible for degrading the skin’s extracellular matrix and structural integrity thereby contributing to wrinkle formation, skin laxity and telangiectasia (visible capillaries). MMPs increase naturally with age and exposure to sunlight. As a side note, lactobionic acid is currently used in organ transplant preservation fluids to help protect organs during medical procedures due to its potent antioxidant effects.
