I enjoyed using this product and saw a smoother finish to my skin. It absorbed quickly into my skin and left no shine behind. One and a half pumps for full face, neck and decollete every day. This product disappeared fast as it is only 15 ml. Not sure I’ll continue use due to the price. That’s why I gave it only 4 stars. Exosomes are great for skin, but I can’t justify such a small bottle for the price.
