About
A lysate (broken-cell fraction) from human egg cells, marketed for growth factors. Ethically and biologically problematic — strongly advised to avoid.
Human oocyte lysate is the cellular content released by lysing human egg cells (oocytes), proposed for cosmetic use as a source of growth factors, proteins, and signaling molecules. The ingredient raises serious ethical concerns about the sourcing of human gametes for cosmetic purposes; many jurisdictions restrict or prohibit cosmetic use of human-derived cellular material under tissue-donation, biotech, and bioethics frameworks. Biologically, undefined growth-factor cocktails on intact skin carry theoretical risk of stimulating unintended cell proliferation, including in dysplastic tissue. There is no SCCS or CIR safety review supporting cosmetic use. Infectious-disease screening, traceability, and regulatory compliance are very challenging.
