How Bio-Soluble Micro-Point Technology Works
Beyond the 500 Dalton Rule
The external skin barrier is highly selective. According to the widely-known “500 Dalton Rule”, molecules exceeding approximately 500 Daltons (Da) in molecular weight generally have difficulty penetrating.
That creates a challenge for many sought-after skincare ingredients. Hyaluronic acid, collagen, peptides, and PDRN are all far larger than this threshold—so traditional topical skincare has limits.
For years, the common solution has been to break large molecules into smaller fragments. Smaller ingredients may be easier to formulate for topical use, but this can also change the original molecule’s structure.
