In the natural aging process, oxidative stress occurs at a rate at which the body or skin is no longer able to fully neutralize free radicals. Free radicals accelerate the cellular damage known to cause premature aging. Antioxidants have the ability to pair with an unstable electron and reduce cell death. There are actually six categories of free radicals that attack the skin every day. One powerful antioxidant alone cannot stand up to all of them. HydroPeptide® contains a variety of natural and organic antioxidants that provide a broad range of protection to fight all six categories of free radicals.
