Each capsule contains 500 mg of hydrolyzed collagen, also known as peptides. Here’s how they work. Sustainably sourced collagen from fish skin and skeleton, when hydrolyzed (broken down into smaller pieces called peptides), are more easily digested and absorbed within the bloodstream. These peptides then fuel the growth of type 1 collagen, which accounts for approximately 80% of the protein that forms the dense network of tissue called the dermis. The dermis in turn serves as structural support for the epidermis, the surface layer of skin where wrinkles appear which reflect your age, appearance, and image. Pure Collagen Radiant Skin also contains 6% elastin, the complementary protein which forms a matrix with collagen. Elastin adds flexibility to skin which helps it adapt and retain its look following everything, including your smile.
