Sunscreens Linked to Skin Allergies


Sunscreens are linked to allergies according to studies.

Sunscreens might not be as healthy as advertised. We find studies that have linked sunscreens to a number of adverse conditions. Now we find they are linked to skin allergies.

Sunscreens and skin allergies

Researchers from the Dermatology Department of France’s Angers Center University Hospital found that the common sunscreen ingredient, octocrylene, was linked to  atopic dermatitis – the medical term for skin allergies.

The research, led by Dr. Avenel-Audran last July, studied 50 cases of skin allergies, and found that 10 of 11 the allergic children were allergic to octocrylene, 9 of 28 patients with photoallergies were sensitized to octocrylene, and 11 of 14 adults who were sensitive to ketoprofen were also allergic to octocrylene.

The researchers concluded that:

“Octocrylene appears to be a strong allergen leading to contact dermatitis in children and mostly photoallergic contact dermatitis in adults with an often-associated history of photoallergy from ketoprofen. Patients with photoallergy from ketoprofen frequently have positive photopatch test reactions to octocrylene. These patients need to be informed of sunscreen products not containing octocrylene, benzophenone-3, or fragrances.”

Other research confirms link

Other studies have shown that other sunscreen ingredients are also linked with allergies. These include clinical studies.

Research from Australia’s Skin and Cancer Foundation (Cook and Freeman 2001) reported 21 cases of photo-allergic contact dermatitis caused by oxybenzone, butyl methoxy dibenzoylmethane, methoxycinnamate or benzophenone. The Cook and Freeman research has led to a conclusion that these sunscreen ingredients are the leading cause of photo-allergic contact dermatitis.

A study at the National Institute of Dermatology in Colombia conducted a study of eighty-two patients with clinical photo-allergic contact dermatitis. Their testing showed that twenty-six of those patients—31.7%—were shown to be positive for sensitivity to one or several of the sunscreen ingredients (Rodriguez et al. 2006).

It is not as if sunscreens simply stay on top of the skin surface. A study done at the University of Manitoba in Winnipeg (Sarveiya et al. 2004) reported that all sunscreen ingredients tested—including octymethoxycinnamate and oxybenzone—significantly penetrate the skin. The penetration of common sunscreens was found to increase the penetration of even more dangerous herbicides—a concern for agricultural workers and non-organic gardeners (Pont et al. 2004).

Research has also found that farming monoculture also contributes to allergies. Antibiotic use is also linked to allergies and hay fever.

Case Adams is a California Naturopath with a PhD in Natural Health Sciences, and a Board Certified Alternative Medicine Practitioner. He has authored 26 books on natural healing strategies. “My journey into writing about alternative medicine began about 9:30 one evening after I finished with a patient at the clinic I practiced at over a decade ago. I had just spent the last two hours explaining how diet, sleep and other lifestyle choices create health problems and how changes in these, along with certain herbal medicines and other natural strategies can radically yet safely turn our health around. As I drove home that night, I realized this knowledge should be available to more people. So I began writing about health with a mission to reach those who desperately need this information. The strategies in my books and articles are backed by scientific evidence along with wisdom handed down through traditional medicines for thousands of years.”
