Pyrimidine Nucleotide Collagen Promoter for Skin Barrier Bypass

The patent introduces nucleotide compounds (adenylic acid, uridylic acid, cytidylic acid) as intermediary substances that act as signaling molecules to stimulate fibroblasts to produce collagen, rather than directly supplying collagen protein. These nucleotides penetrate the skin barrier and trigger endogenous collagen synthesis, resolving the issue of external collagen inability to penetrate skin.

The patent replaces the mechanical approach of physically delivering collagen protein to the skin with a biochemical signaling approach using nucleotide compounds. Instead of relying on collagen molecules to penetrate skin barriers and be absorbed, the nucleotides serve as chemical signals that activate collagen production pathways within fibroblasts, achieving the same goal through a different mechanism.

The patent uses nucleotide compounds as intermediary signaling molecules that can penetrate the skin barrier and stimulate fibroblasts to produce collagen internally. This avoids the problem of large collagen molecules being blocked by the skin barrier, as the small nucleotide signals can pass through and trigger collagen synthesis from within.

Instead of trying to deliver collagen to the skin (external application), the patent inverts the approach by delivering signaling molecules that trigger internal collagen production. The nucleotide compounds are applied to the skin, penetrate the barrier, and then activate the skin's own fibroblasts to synthesize collagen, achieving the opposite sequence of delivery and production.

The patent combines multiple nucleotide compounds (adenylic acid, uridylic acid, cytidylic acid) working synergistically to achieve robust collagen production. While individual pyrimidine nucleotides showed limited effect, the combination of all three nucleotides creates a comprehensive signaling system that strongly stimulates fibroblast collagen synthesis, overcoming the limitation of single-nucleotide effectiveness.

The patent employs a multi-functional nucleotide-based signaling system where adenylic acid, uridylic acid, and cytidylic acid each contribute different aspects of collagen production stimulation. This universal approach using multiple nucleotide types ensures reliable and robust collagen synthesis, as the combined action of different nucleotide signals provides comprehensive activation of collagen pathways.
