Brand from Japan: MIZUHASHIHOJYUDO. Premium Stem Cell Conditioned Media by MIZUHASHIHOJYUDO.This is a highest-grade stem cell conditioned media developed with pride by MIZUHASHIHOJYUDO.Human stem cells naturally release proteins known as cytokines (growth factors), which support cell activation, growth, and regeneration. These cytokines help restore damaged tissues and maintain healthy cellular function. Human stem cell conditioned media is obtained by culturing stem cells, followed by centrifugation and sterilization to collect the purified supernatant. This supernatant contains hundreds of types of cytokines and is expected to support cellular revitalization and overall skin and wellness care.Because even high-quality conditioned media cannot deliver results if it remains only on the skin surface, the TERASTEM serum adopts a proprietary penetration technology.This confidential delivery system enables beneficial ingredients to penetrate quickly into the skin (stratum corneum) and remain there, helpin
