The thickness of skin, the bounce, the fullness we see in youth has a lot to do with EFA's. Linoleic Acid and Alpha Linoleic acid known as Essential Fatty Acids (EFA's) have been overlooked externally (and internally) as an answer to increase skin thickness in thin, fragile, aging skin.
EFAs are essential constituents of skin cell membranes. When, in time, skin loses EFAs, skin can become crepe-paper thin. For cell membranes, Reviva Labs has developed a complex of 10 oils rich in the Linoleic acids and supported by elements that help create a fuller, smoother look and feel to thin skin on face and hands.
