Elemis Pro-Collagen Marine Oil is one of the nicest face oils Ive tried.  Unlike other brands, this emollient is quickly absorbed and doesnt leave an oily appearance like so many others do.  I use it instead of a moisturizer before applying make-up.  Three drops is plentyone on my forehead and cheeks is enough to massage around my entire face.  It works best if I apply it to a slightly wet face.  The oil makes an excellent base for liquid make-up, and helps spread it more smoothly and evenly.  The end result is a natural look that I like very much.
