METSV says:   Ha!  So funny that before I even read the blurb on this, I had been using it and saying to myself "man, this stuff hydrates like nobody's business" and lo and behold, apparently SKN feels the same way about this superstar oil.   If you are not familiar with the wonder that is squalene, (from the olive, not the shark) you should become acquainted with it.  To use it is to fall in love with the incredible hydration and moisture and glow that it provides...Squalene is a treat for the skin.   To find a product whose ingredient list includes all of ONE ingredient - the headliner - then, yep, I'd say you have a pretty powerful serum.  I don't detect even a hint of fragrance and I have found this to cause absolutely no problems or irritation to my skin.  Just incredibly soft skin - baby bum soft!   Great to use after exfoliating, doing a peel, frying at the beach, flying (talk about sucking the moisture right out of your face), skiing on the mountains - whenever your face needs an extra boost of hydration, then SKN is the way to go...I've been trialing another product in the "sexy" black bottle series and I'm loving that one just as much.  The prices for such pure product are unbelievable.   A must try for the ultimate in moisture.  Love.
