How Is It Made?

Over a 20 day period

• Keratinocyte medium is replaced by a maintenance medium
• Cells continue to mature
• Distinct epidermal and dermal layers are present
• Developing bilayer is air-lifted (exposed to air)
• Incubated (air-liquid interface) for 10 days1,2
  • Enhances maturation of keratinocytes in epidermal layer
  • Produces a stratum corneum (cornification)
