It was originally developed as a medical food supplement, being the fraction of the oil that is most easily digested.  I suppose that is why it has such an odd name.  But it was soon picked up by cosmetic chemists.  We appreciate it for its lack of odour, its resistance to oxidation and the fact that being highly purified you are unlikely to have many components in it that give rise to allergies.   As such it is a good substitute for mineral oil  if you want to formulate without petrochemicals.  It isn’t quite as good as a skin barrier builder as mineral oil, but it is usually good enough.  It has a better skin feel than mineral oil, so it works well in formulations that need a high oil content  like oil based cleansers .

Instantly hydrate your skin. HADA LABO Goku-jyun Light Lotion should be used after washing with HADA LABO Goku-jyun Face Wash and serves as the foundation to your moisturizing routine.
