This Popular Moisturizer Applied To Mice For 17 Weeks Got 69% More Tumors

A study has found that topical applications of moisturizers such as Dermabase, Dermovan, Eucerin Original Moisturizing Cream, or Vanicream could increase skin cancer risk.

Mice irradiated with moisture intake reportedly experienced a faster increase in the risk of tumor growing and increased tumor size. Treatment of the mice with Dermabase, Dermovan, Eucerin, or Vanicream for 17 weeks increased the total number of histologically characterized tumors by 69 percent.

A recent study reported that some commercial moisturizing creams increase the formation and number of tumors in laboratory mice. The next studies are needed to know how their impact on a human being.

This also applies to tanning oils and lotions, which many of you may be using right now with summer in full swing, as well as the baby oil or lotion that many parents unwittingly slather on their babies.

Many skin creams contain mineral oil, which is derived from petroleum, which is used on your car.

Mineral oils are carcinogenic. Mineral oil is also comedogenic, blocking human’s pores and preventing the skin’s respiration process.

Blocked pores can lead to blackheads and pimples. Moreover, because mineral oil can create an impenetrable film on your skin, it may also block the absorption of any beneficial ingredients that might exist in the product.

Moisturizing cream with mineral-based oil can be tumorigenic

The featured study, published in the Journal of Investigative Dermatology, found that commonly used moisturizing creams containing mineral oil are tumorigenic when applied topically to mice. What this means is that these creams and lotions can increase the rate at which skin tumors form. The study tested four common skin lotions:

Dermabase
Dermovan
Eucerin Original Moisturizing Cream
Vanicream

What these creams have in common is that they all contain mineral oil. Mice that were at high risk of developing skin cancer received a topical application of 100 mg of one of the creams once a day, five days a week for 17 weeks. The researchers concluded that the rate of tumor formation significantly increased, as did the tumor size per mouse. In fact, the number of histologically characterized tumors increased by a whopping 69 percent!
