When we realise the absorbency of the skin, it becomes obvious that we need to be careful what we put on it. If we use personal products that contain chemicals then those chemicals can find their way into the cells of our body.
Because there are so many chemicals used, it is probably easier and safer to use only 100% natural products. That would save trying to know the names o,f and understand the problems associated with each chemical. In fact most personal care products are not required to list all of the ingredients on the labels, so it becomes difficult to know exactly what we are putting on our skin.
To give some idea of the scope of the problem there are more than 125 ingredients used on the skin that are possible carcinogens. 25 of them are associated with possible birth defects.
Reports show that hundreds of man made chemicals and residues have been found in breast milk and fat cells of people. No one really knows the extent of the health problems that these can cause.
Even products like toothpaste, deodorants, body lotions and hair conditioners can contain chemicals like propylene glycol that can cause eye and skin irritation, headaches and nausea.
