Aquaphor contains mineral oil, which is not a recommended ingredient in cosmetic and personal care products.
Mineral oil is a clear, liquid oil with no scent and will not spoil. It is produced as a byproduct of the distillation of gasoline from crude oil, so it is a petroleum by-product. Mineral oil is leftover liquid, and because it is abundant, it is very inexpensive.
The problem is that mineral oil is foreign to the human body and has many harmful effects, especially in infants. Some of the effects of mineral oil may be a little surprising.
Mineral oil acts as a thin layer on the skin. It is difficult to absorb and clogs the pores, which slows the skin's ability to eliminate toxins, promoting acne and other disorders. As well, it slows down skin function and cell development, resulting in premature aging. Manufacturers use petroleum because it is unbelievably cheap.
