Squalane is a natural extract found in olive oil originally discovered in Japan. Natural Squalane may be applied at any time to provide extra moisture to the skin. Squalane is a natural occurring oil having a similar structure to sebum, the skin's own moisturizer. Squalane is recognized as one of the most effective moisturizers available. Now we also have it with Vitamin E which is great for promoting the healing of the skin, relieves dryness, slows collagen degradation, and protects skin cells and membranes. This product is great for post-surgery clients.
