Raw Shea Butter
I love Shea Butter. My face gets extremely dry in the winter, and this is the only moisturizer that works for me. I put it on immediately after getting out of the shower, and the moisture lasts at least 24 hours. Also, Shea Butter is naturally high in vitamins A & E. It protects from UV Rays, reduces scars, helps cell regeneration and capillary circulation. My face has never looked more healthy!
I have tried both raw and refined butter and I prefer the raw. I found that the refined butter didn't moisturize as well, and it also irritated my eyes. However, I don't mind the nutty smell of the raw butter, so there's no reason for me to choose refined. Also, the refining process removes many of the beneficial properties of shea butter. Here's a quote I found from another website: http://www.treasuredlocks.com/shebutben.html
"The differences between raw, refined and highly refined Shea Butter lie in how the Shea Butter is extracted from the nut and how it is processed after that. Manual extraction processes leave more of the raw ingredients in the Shea Butter. After it is extracted, it can be further refined removing color and impurities that some people don't like. This further refining can also remove some of the smell. You can think of the difference between raw Shea Butter and refined Shea Butter as being similar to the difference between wheat bread and white bread. Truly raw Shea Butter can even be unfiltered. That is one end of the spectrum. On the other end, there is Shea Butter that is extracted using chemicals that is pure white, has no smell and has lost a lot of its healing properties in the process."
The website listed above also answers many other questions about Shea butter. I recommend checking it out.
