What is Paraben Allergy?



The FDA doesn’t regulate the chemicals in cosmetics and it’s up to consumers to be aware of the chemicals we put on and in our bodies on daily basis.  More and more, people are experience allergy to their cosmetics and personal care products.  These reactions cause itchy red swollen skin. As a cosmetic allergist, I have many patients who are a loss for what’s triggering the reaction. They know that certain lipsticks make their lips dry and irritated or sometimes a shampoo will trigger itchy dry irritated skin, but are confused about the exact cause.  This type of allergic reaction is called contact dermatitis.  

One common allergen in personal care products that triggers an itchy eczematous rash is parabens. 


What are Parabens?
  • Parabens first introduced in the 1920’s are preservatives to help prevent bacterial and fungal growth.  Since their introduction, they’ve become some of the most common preservatives uses. 
  •  Parabens come from an aromatic organic acid naturally found in fruits and vegetables called 4-hydroxybenzoic acid.  This forms the basis for parabens.
  •  There are many types of parabens, but the most commonly used ones are methylparaben, propylparabens and butyl parabens.  These types of parabens are often mixed into one product type to provide broad spectrum protection against microorganisms.  Manufacturers do these to reduce the concentration of each one individually but provide the same type of preservative effect.

  • Parabens can also cross react with chemical commonly used in sunscreens – para-aminobenzoic acid (PABA) esters, and in hair dye (paraphenylenediamine).
·      Parabens may also go by these names:
o   Methylparaben
o   Ethylparaben
o   Propylparaben
o   Butylparaben
o   Benzyl-parahydroxybenzoate (p-hydroxybenzoate)
o   Methyl-parahydroxybenzoate (p-hydroxybenzate)
o   Ethyl-parahydroxybenzoate (p-hydroxybenzoate)
o   Propyl-parahydroxybenzoate (p-hydroxybenzoate)
o   Butyl-parahydroxybenzoate (p-hydroxybenzoate)
o   Parahydroxybenzoate (p-hydroxybenzoate)


Where do you find Parabens?
  • Parabens in personal care products:
    • According to the American Chemical Society, they are used in almost 85% of all personal care products.  Common products like toothpaste, shampoo, lotions, sunscreens, moisturizers and lipsticks contain parabens.  They are also found in some topical medications like corticosteroid creams and anti-itch sprays. 
  • Parabens in food products:
    • You might be surprised to learn that parabens are added to food products like: pancake syrup, mayonnaise, salad dressing, baked goods, candy, food dye, soft drinks and fruit juices, spiced sauces, processed vegetables, and jams/jellies
    • Parabens are also found naturally in food products like mango, blueberry, mango, strawberries, cocoa beans, carrots, vanilla, and onions.
    • You can also find parabens naturally in some wine and beer products.

What is Paraben Allergy?

  • Repeat exposure to skin, particularly damaged skin, but parabens can trigger an allergic reaction called contact dermatitis.
  •  According to a 2015 study by Warshaw et al, parabens caused anywhere from 1.4% of of all contact reactions. Exposure to parabens can cause your skin to become dry, itchy and swollen.


What Should you Do if You Suspect You Are Allergic to Parabens?
  • If you suspect you have paraben allergy, speak with your allergist about having a special chemical allergy test done called patch testing. 


How Can you Avoid Parabens?
  • If you have paraben allergy, then you should strictly avoid any product or food that contains these chemicals
  • Reading ingredient lists on your personal care products and food labels will be essential to preventing a future reaction.
  • Using products that are oil based will help limit your exposure
  • Be especially careful with sunscreens, processed foods, topical medications and other unexpected sources of parabens.  
  • If you visit gramercyallergy, we will generate a paraben free list of products you can safely use.

Allergy to the Sun or Sunscreen Allergy

Everyone is talking about the importance of regular use of sunscreen (SPF 30-50) to protect your skin from the suns UVA and UVB rays.   Using regular sunscreen is a must to help prevent skin cancer and prevent early signs of aging. Lately, I've had several patient coming in complaining they've developed a serious rash in the spots they've applied sunscreen.  What do you do if you suspect or have sunscreen allergy?

Who's at Risk For Sunscreen Allergy?
  • In the general population 1% of people have contact dermatitis
  • About 1% of the population who  has contact dermatitis has sunscreen allergy
  • Persons with dry cracked skin (eczema)
  • Regular use of sunscreen
  • Female and,
  • being younger than 40
What are Signs/Symptoms of Sunscreen Allergy?
  • A itchy red rash at the sites sunscreen was applied
  • Typical spots are the face and neck, but it can be anywhere on your body.
What are Most Common Causes of Sunscreen Allergy?
  •  Benzophenone-3  ( a chemical that helps absorb UV rays from the sun)
  • DL-alpha-tocopherol, and
  • Fragrance mix
  • Other chemical absorbers ( they act like a mop for UV rays) can also be the source of an allergic reaction
    • PABA's,
    • Cinnamates :Octocrylene, Octyl methoxycinnamate (octinoxate), and Ethoxyethyl p-methoxycinnamate (cinoxate)
    • Salicylates: homomenthyl salicylate, ethylhexyl salicylate, and trolamine salicylate
    • Avobenzone, Ecamsule, Ensulizole, bemotrizinol, biscotrizole

What Should You Do if You Suspect You Have Sunscreen Allergy?
  • See your local allergist to get patch tested.
  • This will help determine which chemical is causing your rash
  • Or if a chemical on your skin is being activated by the sun (photodermatitis)

What are Some Safe Alternatives if You Have Sunscreen Allergy?
  • You can use physical blockers like titanium oxide and zinc oxide
  • These will protect your skin from  UVA and UVB rays.
