    You do understand that it’s not physiologically possible for this to actually lighten skin, right?

    The fact that shea butter is in the soap does not mean it will have any effect. It won’t, except that it will increase hardness and reduce lather. In order to get a skin lightening effect with shea butter, it is necessary to formulate it as a cream or lotion or other form of product that is applied to and absorbed by the skin. It is the retinol in shea that is responsible for the effect, and it is best to use unrefined class A organic shea if you want it to prove effective.

    Your formula does not have effective lightening ingredients in it. You need kojic acid/vitamin C/niacinamide etc to have lightening effect. Beside, you are formulating a soap to be washed off in a minute. It does not make sense to apply a lightening ingredient and wash it off right away.
