Revising the ingredients of your skin care product, you will find that good brands include either Squalene or Shea Butter in their formulations. Both substances are excellent as emollient and moisturizers that maintain a normal healthy water content in the skin.
Squalene is found in nature in Olives, Palm oil and Wheat Gerrm oil. It is a normal metabolite of the human body as it is the precursor of the whole family of steroids, yet its greatest concentration is in the skin. Shea Butter is a natural fat that is the product of the Shea or Karite tree that occurs in 19 countries across the African continent.
They share the following characteristics:
# They do not oxidize or turn rancid
# They absorb rapidly into the skin without leaving a greasy feeling
# They both can can improve chapped lips, cracked feet, dry hands and cuticles, as well as they soften rough areas like knees, elbows and soles. They offer deep conditioning treatment for hair
# They can be used for foot rub with or without Vaseline They can be used in making baby body care products
# They are commonly used in products that treat wrinkles and fight aging by increasing suppleness and smoothness of the skin, thus decreasing fine lines and skin aging
It is much better if you can get them both in your skin care product, yet you may consider the following notions:
# If you take statins (Lipitor,Mevacor,Zocor..etc.) that inhibit Squalene synthesis to prevent Cholesterol synthesis and reduce it in the blood, then you need to search for Squalene to compensate for
# If you are exposed to sun for long periods, you need both, since Shea Butter provides natural UV protection of SPF ranging from 0 to 6, and Squalene has antioxidant effects that may prevent oxidative damage from UV light
# If you have a family history of skin cancer or you had a preexisting tumors, it is better if you get them both to benefit the sun screen protection of Shea Butter. There is accumulating evidence that Sqalene prevents the chemical irritation of some kinds of cancer, and promotes the regression of some kinds of preexisting tumor.
# If you need antiaging cream,it is better if it contain both. In fact, you need them both.
