Hold the phone: Prolonged cell use can trigger allergic reaction, as can body piercing, tattoos and cosmetics

"Increased use of cell phones with unlimited usage plans has led to more prolonged exposure to the nickel in phones," said allergist Luz Fonacier, MD, ACAAI Fellow. "Patients come in with dry, itchy patches on their cheeks, jaw lines and ears and have no idea what is causing their allergic reaction."

Nickel is one of the most common contact allergens, and affects up to 17 percent of women and 3 percent of men. Contact with objects containing nickel, such as keys, coins and paper clips are generally brief, so the nickel allergy may not occur on the area of contact. However, even in these brief encounters, nickel can be transferred from fingers to the face and cause eyelid irritation. The risk is increased by frequent, prolonged exposure to nickel-containing objects, such as cell phones, jewelry, watches, and eyeglass frames.

"Allergists are seeing increasing numbers of nickel allergy among patients," said Dr. Fonacier. "Some researchers suggest that there should be more nickel regulation in the U.S. like there is in some European countries."

Symptoms include redness, swelling, itching, eczema, blistering, skin lesions and sometimes oozing and scarring. Avoidance of direct skin contact is the best solution. For cell phones, try using a plastic film cover, a wireless ear piece, or switching to a phone that does not contain metal on surfaces that contact the skin, suggests Dr. Fonacier. However, identifying the allergen and avoiding it is the only long term solution.

Body Piercings & Tattoos

You can also have an allergic reaction to your body art (piercing and tattoos). Twenty-four percent of people 18 to 50 years old have tattoos and 14 percent have body piercings.

"Allergic reactions from tattoos come mainly from the pigments used to color the dye," said Dr. Fonacier. "The issue with body piercing goes back to the increasing prevalence of nickel allergies. Some researchers suggest we delay introduction of ear piercing until children are older than 10 years."

Cosmetics

"It's well known that our everyday cosmetic products contain many substances that cause allergies," said Dr. Fonacier. "Although the cosmetic industry is one of the largest in the world, it is not highly regulated in the U.S. The average person uses 12 personal products a day. Those 12 products may contain up to 168 chemicals, many of which can be an irritant or a substance that causes an allergic reaction."

Nearly 22 percent of everyone patch tested for allergies react to chemicals in cosmetics, according to Dr. Fonacier. Fragrance and preservatives contained in cosmetics cause the most allergic reactions. Common allergy symptoms from cosmetics include: redness, itching, crusting, swelling, blistering, dryness, scaliness and thickening of the skin.

Those who suspect they have allergies to cosmetics, tattoos or nickel should be tested by an allergist -- a doctor who is an expert in diagnosing and treating allergies and asthma.
