Squalane is a natural essential emollient found in our own skin. It is responsible for aiding moisture retention and cell regeneration. As we age we produce less squalane in our own bodies. We can replenish it with natural olive squalane. It is a beautiful light, colorless. and odorless fluid which is absorbed deeply and immediately into the skin. Use after regular cleansing and before regular moisturizer. It is also an excellent primer for mineral make-up. Compatible with most skin types. Use daily, just a few drops at a time. Results are usually noticable after just a few days.
