DNA Polynucleotide (PN) is a bio-based cosmetic ingredient, a purified DNA fragment extracted from natural sources such as salmon sperm or microbial fermentation. It belongs to the class of nucleotides and oligonucleotides, known for their structural and regulatory roles at the cellular level. In cosmetic science, PN interacts with the skin surface at the molecular level, helping to maintain moisture balance and support normal skin physiological functions.
DNA Polynucleotide is supplied in a water-soluble powder form and is compatible with various topical skincare formulations. Its stability under standard storage conditions and good compatibility with commonly used cosmetic ingredients make it easy to incorporate into products such as creams, serums, and gels.
