Human cells are made up of various components called organelles. Exosomes form when these organelles fuse with the cell wall creating tiny sacs that are then released and taken up by other cells.
The exosomes carry important components within them like proteins, DNA, RNA, growth factors and nutrients which can be essential for skin regeneration that we can bring directly to the skin.
As our bodies get older, stem cells signal less. They don’t send out as many of the exosomes that tell our other cells how to perform optimally and keep our bodies young. So cells get tired and function less well, and aging happens.
