Common Name(s): Xanthine,xanthine,nucleobase,skin cell dna/rna repair support
CAS Number: N/a
DESCRIPTION
What It Does: Provides xanthine nucleobase substrate for skin cell dna repair, rna synthesis, or purine catabolism regulation depending on the specific nucleobase pharmacology.
Why It's Used: Xanthine is selected for its nucleobase-mediated cell metabolism support — providing the specific pyrimidine or purine substrate that activates dna repair, rna synthesis, or energy metabolism pathways relevant to anti-aging and cellular maintenance.
How It Works: Xanthine: nucleobase salvage pathway → nucleotide synthesis → dna/rna synthesis; cell cycle support → keratinocyte turnover normalisation; purine/pyrimidine substrate delivery.
Typically Found In: Anti-aging,cell repair

SCIENTIFIC NOTE
Xanthine is absorbed via nucleobase transporters in keratinocytes — the salvage pathway provides an energy-efficient route to nucleotide synthesis bypassing de novo biosynthesis.
