Exosomes are nano-sized vesicles released by cells, containing signaling substances such as growth factors, proteins, and microRNA. When these particles contact skin cells, they are known to activate intercellular signaling, stimulating fibroblasts and increasing the production of collagen and elastin. CellExosome BLACK LABEL delivers these exosomes along with culture medium ingredient AAPE®, plant-derived exosomes, and liposomal SOD capsules to the upper dermis.
