The Truth About Ingredient Labels
Even when the ingredient name is the same, the actual efficacy varies significantly depending on the raw material manufacturer and degree of purification.
Cosmetic raw materials are originally developed by major manufacturers (Sederma, BASF, Evonik, etc.) and validated through clinical trials. Once patents expire, generic manufacturers produce the same chemical structures at lower cost.
Original materials have 95-99% purity with RCT (randomized controlled trial) data. Generic materials have 50-80% purity with no data. Yet the same name appears on the ingredient list.
Human stem cell conditioned media exhibits even greater quality variation, with composition fluctuating based on donor status and culture conditions. Growth factors may include undesirable ones such as VEGF.
In contrast, chemically synthesized peptides have fully defined molecular structures, controllable purity, lot-to-lot uniformity, and contain no unwanted growth factors. "Knowing exactly what is in it" is the greatest advantage of synthetic peptides. "Naturally derived" or "human-derived" does not inherently mean better -- efficacy should be judged by reproducibility of results.
