My teen daughter, Meg, has been through a terrible time with skin problems.  In addition to the normal acne, she also has psoriasis, so it is really hard to find soap that works on the acne but also does not irritate the psoriasis.  A friend of mine suggested that we learn how to make soap.  There are only four ingredients in our home made soap, and none of them are an irritant.  We use only mild dyes that she can tolerate, and very mild but pleasant scents that she like,  She loves having nice soaps that smell good, and her skin is in the best condition it has been for years.
