Do Parabens Cause Allergic Dermatitis?
Since the 1960s, there has been controversy over paraben use and safety because it is a possible cause of allergic contact dermatitis. Despite the cloud of suspicion since those times, multiple studies over the last 40 years have not produced any definitive evidence on its toxicity. In fact, they are the least sensitive preservative for commercial use.
There are conflicting reports of the effects of parabens on the skin. Some reports suggest that the presence of these chemicals in food cause unexplained dermatitis, while others show that even concentrations up to 5% do not cause skin irritation.
So, Why Are Parabens Bad?
There is little evidence that explain why parabens are bad, or if they are indeed harmful. Currently, there are no clear health risks of these chemicals in food, medicines, cosmetics and skin care products. But those concerned about exposure to products containing these chemicals can avoid them by checking the labels.
The truth is most people are exposed to parabens. In fact, studies show that up to 99% of people in the United States have some form of paraben in the urine. Meanwhile, other studies have failed to prove a direct link between them and health problems such as breast cancer.
