All it takes is a special ingredient in your natural soap recipe and it is possible to get an ant- ageing effect in your soap. I am getting positive results from this.
What is it? Colloidal Copper Citrate. Use this for your lye water or add it to your natural liquid soap.
See my blog on "Using Colloidal Copper in Natural Soap" July 13 2017.
Because pollutants, illnesses, excess stress and or poor diet you may not get the results desired but it will work for some.
