Collagen

Collagen is the most abundant protein in the human body, accounting for approximately 30% of total protein mass and forming the structural scaffold of the skin, tendons, ligaments, and cartilage. In the skin specifically, Type I and Type III collagen fibers provide tensile strength, volume, and the physical resilience that gives young skin its characteristic firmness and elasticity. These fibers are organized in an intricate three-dimensional network within the dermis, supported by elastin and hyaluronic acid. The decline in collagen synthesis is one of the most significant biological drivers of skin aging. Beginning in the mid-twenties, the body’s natural production decreases by approximately 1% per year. Simultaneously, existing collagen fibers are progressively degraded by enzymes activated by UV radiation, oxidative stress, and chronic inflammation. The combined effect — reduced synthesis and increased degradation — results in loss of skin thickness, volume, and structure, manifesting as fine lines, wrinkles, and sagging. Oral supplementation with hydrolyzed collagen peptides has been shown in randomized controlled trials to significantly counteract this decline. A 2019 randomized, placebo-controlled, blind study published in Nutrients confirmed significant improvements in skin hydration, elasticity, roughness, and density following collagen supplementation. In SKINperfect, collagen serves as the primary structural ingredient, providing the foundational building blocks for the skin’s own renewal and repair processes.
