Allergic contact dermatitis develops when your immune system reacts to a substance that touches your skin. Instead of causing immediate symptoms, like sneezing or watery eyes, this type of allergy often leads to redness, itching, swelling or a rash where the skin comes into contact with the substance.
Many everyday products contain ingredients or materials that can trigger an allergic reaction. Understanding the most common culprits can help you reduce flare-ups. Let’s look at three possible sources of irritation—nickel, fragrance and medications—and how you can minimize your contact with them.
Nickel Allergies
Nickel is the most common cause of metal allergies.[1] You may encounter nickel in items including, but not limited to:
- Earrings, necklaces, bracelets and rings
- Watchbands and eyeglass frames
- Belt buckles, snaps, zippers and bra fasteners
- Keys and coins
- Kitchen utensils and cookware
- Bathroom fixtures
- Razors and grooming tools
- Musical instruments
Some foods contain nickel as well. If your nickel allergy is severe, we may recommend dietary changes in addition to avoiding direct skin contact with the substance.
Fragrances
Many personal care and household cleaning products contain fragrances. Most fragrance irritation stems from sensitivity rather than a true allergy, but this sensitivity can present with or worsen allergies or asthma symptoms.
Common fragrance sources include:
- Perfumes and colognes
- Lotions and moisturizers
- Soaps and shampoos
- Deodorants
- Laundry detergents
- Air fresheners
- Scented candles
- Household cleaning products
Choosing fragrance-free personal care products and cleaners will reduce your exposure. If strong scents regularly bother you, creating fragrance-free spaces at home or work can significantly lower your exposure.
Topical Medications
Some topical medications can trigger allergic contact dermatitis. Potential triggers include:
- Topical antibiotics
- Corticosteroid creams
- Local anesthetics
- Products containing propylene glycol
- Antifungal medications
- Pain-relief creams and gels
- Anti-inflammatory creams
- Some moisturizers and cleansing products
Before using an over-the-counter product, review the ingredient label to check for substances you’ve reacted to in the past.
When to See an Allergy Specialist
If you have recurring rashes or aren’t sure what’s causing your skin irritation, allergy testing can help identify the source. Once you know your triggers, you can make informed choices about the products you use every day and take steps to prevent future flare-ups.
