An INCI-registered cosmetic ingredient from EHL Bio
Quick answer
Stem cell conditioned media is the fluid produced while culturing stem cells, containing growth factors, cytokines, fibronectin and collagen. EHL Bio's EHL-Stem is INCI-registered as Human Adipose Stromal Cell Conditioned Media. Independent laboratory testing (Dermapro, January 2016) reported a 49% reduction in melanin production, 45% inhibition of tyrosinase and roughly a 9-fold increase in intracellular collagen synthesis.
Those figures come from cell-level (in vitro) assays, not randomised controlled human application trials, so read them as ingredient potential rather than a promise that every finished product containing it performs identically.
Analysed components in EHL-Stem include VEGF, FGF, TGF, PDGF, HGF and EGF — growth factors tied to angiogenesis, tissue repair and fibroblast stimulation.
On safety, the company states it uses only conditioned media meeting Korea's MFDS safety criteria, with safety studies run with GLP-accredited Biotoxtech, and formulations free of parabens, alcohol and colourants.
Bottom line for Thai consumers: conditioned media is a topical cosmetic ingredient, not a disease treatment. If you see claims that injected conditioned media treats disease, check its legal status carefully.
No. Cells are filtered out, leaving only the factors they secreted.
Hydration can improve quickly, but wrinkle and brightness changes usually need 8-12 weeks of consistent use, in line with skin turnover.
Paraben-, alcohol- and fragrance-free formulas are usually low irritation, but patch-test on the inner arm for 48 hours before facial use.
Source. Conditioned media is a natural multi-factor mixture from actual culture, whereas some serums add just one recombinant growth factor.
