Elastin is the main ingredient in our skin that allows it to stretch without leaving marks. As we age, our bodies reduce the production of elastin, therefore, making it more difficult for the skin to stretch without producing a stretch mark. To help our bodies produce more more elastin, Elastin3 contains the rare, costly freeze-dried powdered Elastin concentrate which is almost 100% Amino acid content, making it 10 times more potent than standard elastin products used in the U.S. and abroad.
