Polynucleotides promote biostimulation by activating fibroblasts, the cells responsible for collagen and elastin production. This activation leads to increased synthesis of these essential proteins, enhancing skin elasticity, firmness, and overall texture. By improving the extracellular matrix, polynucleotides help restore the skin's structural integrity and resilience. Through a series of microinjections, polynucleotides are delivered directly into the skin, where they initiate these biostimulatory effects. The result is a noticeable improvement in skin hydration, tone, and smoothness, with a reduction in fine lines, wrinkles, and other signs of aging.
