KB304 Payloads Type I Collagen Type III Collagen Type IV Collagen Elastin Percentage in the skin 70-80% 15%-20% Small % 2-3% Function Forms dense, tightly packed fibers that provide firmness and tensile strength Provides flexibility and elasticity, allowing skin to stretch and recover Forms the basal lamina, provides filtration and structural support Provides stretch and flexibility to prevent sagging Aging alteration Increases with growth, decreases with age Abundant in young skin, decreases with age Gradually declines, weakening the skin barrier Abundant in baby skin, peaks in mid- 20s / early 30s and declines thereafter • Type III collagen (COL3) is the second most abundant type of collagen protein in the skin but levels decline significantly with age1 • COL3 is indispensable for youthful, resilient skin2 and has been implicated in both new collagen fibril formation as well as regulation of collagen fibril diameter, organization, and elasticity2 • Elastin is ~1000 times more flexible than collagen, and gives skin its elastic quality3 • The production of elastin, which has a ~70 year4 half-life, peaks near birth and effectively ceases by adulthood5 • Due to the low rate of turnover, elastin fibers are particularly prone to the accumulation of damage from aging (extrinsic aging in particular) • This degradation of the elastin network over time leads to sagging and wrinkled skin 1.
