Because, it is gentle, soft, lathering and not hard on your skin.  It leaves your skin soft and moisturized.  Your skin will never be the same after using a natural/organic handmade soap.  Natural soaps are very different than commercialize soaps.  What you see in stores it is usually a detergent in a bar. Synthetic detergent was originally formulated during the war years when oils & fats for soap making were scarce in supply.  Commercial soap that is actually soap is made with inexpensive oils and they remove the natural glycerin that is produced.  You may ask why do they remove the glycerin? And the answer is because natural vegetable glycerin is humectants, and draws moisture to your skin.  The commercial soap makers remove it and sell it to make glycerin soap and other skincare products.  Often they will add cheap fillers, whiteners and synthetic fragrances.  All these ingredients can be very irritating and drying to your skin.  Your skin is your largest organ, and when you use soap without its natural glycerin your skin will dry out and lose its protective function.

The base of all my soaps is olive and coconut oil, two of the most moisturizing oils for your skin.   And depending what type of soaps I will make I add, avocado oil, apricot kernel oil, cocoa butter, shea butter, hemp seed oil, jojoba oil, and more.
