Exosomes maintain the health of stem cells and protect and deliver the vital molecules that stem cells make such as growth factors, proteins and cytokines. This protective shield around the growth factors have receptor arms on the outside to activate cells and improve penetration. The receptor arms are what make the growth factors easily accepted into our skin and connect to our cell walls; therefore making it more stable and significantly more potent than any liposomal or unprotected growth serum. Growth factors occur naturally in the body and regulate the division and reproduction of cells. Each growth factor has receptors that communicate different "instructions" for each cell. Some "instructions" may include stimulating collagen, protein, blood vessel formation, fibrolasts, immune repair and new cell production. All of these, plus another 150 growth factors are found in StemFactor. The use of exosomes to encapsulate growth factors results in unparalleled performance. Healing of damaged, hyperpigmented, rosacea and aged skin is encouraged, creating healthy, younger, beautiful skin.
