It is impotant to evaluate the penetration speed of cosmetic liquids into skins for developing the cosmetic liquids. In our group, we have developt the penetratiaon depth measuement systems using a THz time-of-flight method. In this presentation we will present the system and the method in detail and demonsrate the penetration speed measurments when the cosmetic liquids were penetrate from the surface of the skin.
