PolyPhil (formerly known as PhilArt) is a line ofinjectable regenerative skin boosters developed by Croma-Pharma that use polynucleotides (PDRN) to stimulate the skin’s natural regenerative abilities. Rather than acting as a filler that adds volume, PolyPhil works as a biostimulator to repair tissue, boost collagen and elastin production, and improve hydration at a cellular level.
