About

Conditioned media from human fibroblast and keratinocyte cultures. Premium serums use it for growth-factor claims, but human-cell sourcing and regulator scrutiny put it at orange.

Skin benefits

  • Used at trace level in premium serums
  • Marketed for skin renewal claims

Known concerns

  • Human-cell origin raises QC and consent traceability questions
  • Possible bioactive growth-factor content concerns regulators
  • No CIR or SCCS dossier specific to these media
  • Composition not standardized
