Semo Squalene is a substance obtained from the liver of 'AI Shark' living in the very deep areas of the oceans. They say it is used for many skin disorders. It is sold in capsules of 2250 mg. and is a bit expensive. It is directly applied to the skin and skin absorbes the substance in 30-40 seconds. It helps the skin to keep soft and moisturized. It is used for acne, kontact dermatit, psoriasis and vitiligo. It is widely used in dermatologic products.

Sounds like snake oil to me.
