GLA
INCI Name:- Gamma Linolenic Acid
Found naturally in oils. The body needs GLA to create Prostaglandins which are needed by the skin to enable it to function properly.
Prostaglandin Deficiency causes skin to age more quickly (becomes dry and wrinkled) and become more light-sensitive. Best source is Borage Oil which has the highest concentration of GLA of any of the oils.
