I have to disagree with wintermoon,it is amazing how much the human skin is capable of absorbing,thus all the precautions about using carrier oils when useing EO's. To get the benifits of any added ingredient from a soap I believe a person must continue to use the product,useing it once or twice will probably not be of noticeable difference to some. 5% shea butter is not much when you really consider it but BB's shea base I believe has a 5% shea addition,which in the list of ingredients would appear towards the end of the list ,but it still makes a difference in the base and on skin. I can tell you that some of my customers will only use this soap on there face and tell me it has improved there complextions. Our skin absorbs everything we put on it even in small amounts. So I agree to disagree.
