Skin Allergies: Causes, Reactions, and How to Avoid Allergens

Skin allergies—like all allergies—are on the rise. Allergic reactions on the skin can range from mildly annoying to potentially deadly, so it's essential to know how to recognize, treat, and avoid them as much as possible.

This guide will describe skin allergies, the common categories they fall into, and what may cause them. We'll also dive into ways to treat and prevent skin allergies, recommend a few of our favorite products, and provide resources.

As always, your physician is the best resource for your healthcare. None of the below information is intended to diagnose or treat ailments or provide official medical advice.

What Are Skin Allergies?

Skin allergies occur when the skin encounters something that makes a person's immune system overreact. People can be allergic to anything—even items necessary for life, like water. While "skin allergies" is the easiest term to use, it's an umbrella covering various specific allergic issues, including (but not limited to) dermatitis and hives.

While experts generally agree that allergic reactions occur when a person's immune system perceives a threat and kicks into high gear to fight it, scientists are still working to understand how the body "decides" what to react to and how to react.

For instance, according to the Columbia University Irving Medical Center, "Poison ivy is a commonly known trigger for allergic contact dermatitis, an itchy skin rash. But many ingredients found in nonprescription topical products can trigger a similar type of rash."

Why could poison ivy cause the same reaction as, say, a face wash? And why are some people not allergic to poison ivy at all? Every time scientists find an answer about allergies, they discover a wealth of new questions as well.

Symptoms of Allergic Skin Reactions

Allergic skin reactions can range from minor annoyances to major health emergencies based on the severity of the allergy, how long a person was in contact with the allergen, comorbid health conditions, and many other factors.

In general, skin allergic reactions are itchy or painful rashes. You may also experience swelling, scaly or flaky skin, and raised bumps. With a skin allergy, you might only experience one symptom or a combination of them.

It's worth noting your skin can react to allergens even when they didn't touch the skin. For instance, if you eat something and break out in hives, you're likely allergic to that food. Though we're focusing on skin care and cosmetic products that come into contact with your skin, it's important to keep in mind that skin reactions don't only happen with skin allergens!

Anaphylaxis is possible but rare with skin allergies. With anaphylaxis, your immune system overreacts more than usual, and you may end up with difficulty breathing, low blood pressure, vomiting, and more. When it comes to skin, this is most common if you have a latex or insect sting allergy, and many cosmetics contain latex. Anaphylactic reactions require immediate medical attention.

Allergies should always be taken seriously. What is "just itching" today could be infected cracks or even anaphylaxis tomorrow. On the flipside, allergies can also get better over time or even go away entirely. Unfortunately, new ones may also develop.

All in all, skin allergies are still a bit of a mystery to the medical community. The key is always to take an allergy or potential allergy seriously and seek medical attention when you suspect an allergic reaction. If it's not an emergency, take photos of your skin reaction with an item for scale, such as a coin, so your doctor can get an idea of what happened if it has healed by the time you get an appointment.

Allergens vs. Irritants

Unfortunately, the differences between allergens and irritants can be confusing.

Like allergic reactions, irritation often involves a rash, itching, cracked skin, and other related symptoms. In fact, due to how similar the symptoms are, contact dermatitis can describe both skin allergic reactions and irritation.

However, the causes are different.

  • Allergens: Things that cause skin allergy symptoms due to an overactive immune system
  • Irritants: Toxic chemicals in cosmetics that may cause an immediate reaction that isn't an allergy
  • Other irritation: Rough physical treatment of the skin, such as frequent handwashing or scrubbing too hard with a washcloth

While irritation isn't the same as a true allergy, it's essential to identify the cause and take steps to prevent it. You can usually tell the difference between irritated skin and allergic skin reactions via the severity of the reaction and if it becomes worse over time.

While irritation can be painful and itchy, it shouldn't be debilitating. If the reaction appears suddenly after many uses of the same product, it may be an allergy. This is because the skin often needs to be exposed to an allergen several times before reacting.

Note: Everyone's body behaves differently. What may appear to be irritation could be an allergic reaction and vice versa. Irritations can later become allergies, too. Always seek medical attention if you have questions.

Are Skin Allergies Common?

According to the International Journal of Environmental Research and Public Health, "The rising prevalence of allergies can substantially impact the skin, which is one of the largest targets for allergic and immunologic responses." Further, allergies as a whole are the sixth leading cause of chronic illnesses in the United States.

The Journal surveyed adults ages 18 to 74 living across the U.S. and discovered 41.7% of them report having allergies. Of those, 41.4% report skin allergies, and 47.7% say their allergies involve skin reactions. An estimated 100 million adults in the U.S. have allergies—this means over 41,000,000 have skin allergies and nearly 48,000,000 experience skin reactions.

But adults aren't the most impacted. Skin allergic reactions are most common among children ages zero to four, and as of 2018, 9.2 million children under 18 in the U.S. had skin allergies.

As mentioned earlier, scientists aren't precisely sure how people's bodies determine when and how to react to allergens. For instance, while latex allergies are common, some people can touch latex without risk but react if they breathe in its fibers or vice versa. So why would your lungs react, but not your skin? Science is still working on an answer.

If a parent has allergies, their children are more likely to have allergies; however, they aren't likely to be allergic to the same things. Additionally, parents having allergies doesn't guarantee a child will, and parents not having allergies doesn't guarantee a child won't.

What is certain is it's rare for a person to be allergic to only one thing. So, if you start to notice skin (or any other) allergies appearing, visiting an allergist to determine all allergens may be wise.

Types of Common Skin Allergic Reactions

Skin allergic reactions look different for everyone, which means there's no all-inclusive list of allergic reactions. However, nearly all skin allergic reactions involve a rash or swelling.

While skin allergies can often improve using antihistamines and anti-itch creams, it's essential to always speak to your doctor for a diagnosis before undergoing treatment or assuming something is a minor allergic reaction. For instance, psoriasis can look like an allergic reaction, but it's actually an autoimmune disorder requiring specific treatment.

That said, here are four of the more common types of skin allergic reactions.

Eczema (Atopic Dermatitis)

While doctors used to believe that eczema was universally an allergic reaction, as research has progressed, they've discovered that most types of eczema are not allergies. Instead, eczema is generally an independent medical condition affecting the outer layer of your skin.

However, allergens can trigger eczema. In fact, the vast majority of kids with eczema later end up with asthma or hay fever. Signs of eczema are different for everyone, but the most common type (atopic dermatitis) includes:

  • Itchy, red rash on face, back of knees, back of the neck, and in the inner elbow
  • Small red bumps
  • Very dry skin
  • Scaly skin
  • Painful, cracked skin (potentially bleeding)
  • Bubble-like rash that can leak clear fluid
  • Creases on palms or under eyes
  • Darkened skin around eyes
  • Itching that worsens at night

If eczema goes untreated for too long, your skin can become dark, thick, and scarred from scratching, or you could develop dangerous infections.

Hives (Urticaria)

There are several types of urticaria, more commonly called "hives." While allergens aren't the only causes, they're often the culprits.

The key to determining if a rash is hives or something else has to do with how fast it appears. No matter how long the hives remain—and an outbreak can last weeks, depending on the type and cause—the reaction needs to have appeared suddenly. Beyond that, hives can look a lot like other rashes: raised, itchy bumps, the centers of which turn white when pressed.

If you develop hives but no other symptoms (e.g., difficulty breathing), make a note of what you were doing as the rash appeared. This sleuthing can help you discover if you're reacting to a chemical, allergen, irritant, or even a stressful situation.

Swelling (Angioedema)

Angioedema is skin swelling, often concurrent with hives. While angioedema is often associated with allergic reactions, it can also happen with no known cause or result from a rare hereditary condition.

Any swelling of unknown origin should be taken seriously. Angioedema swelling usually occurs in large, firm welts that are warm to the touch and may be red or painful.

Contact Dermatitis

Contact dermatitis can be the result of direct physical contact with allergens or irritants. The primary difference between allergic and irritant contact dermatitis is the speed of onset. Allergic contact dermatitis usually takes a while to appear (e.g., several instances of wearing a ring containing nickel). In contrast, irritant contact dermatitis typically occurs immediately after handling a substance.

Whether dealing with allergic or irritant contact dermatitis, you'll end up with a rash. That rash could include one or all of the following skin symptoms:

  • Blistering
  • Flaky
  • Itchy
  • Leaking
  • Painful
  • Red
  • Scaly
  • Swollen

Common Causes of Skin Allergies

Anything can cause an allergic reaction, but some things are way more likely to cause skin allergies than others. When thinking of skin allergies, your mind may immediately go to poison ivy, sumac, or oak, dust mites, pet dander, mold, and other indoor and outdoor allergens we accidentally encounter regularly.

However, there are also many ingredients in cosmetics and personal care products that can cause allergic reactions. These include (but aren't limited to):

  • Preservatives: Formaldehyde releasers, formaldehyde, and parabens are just a couple of the preservatives commonly found in haircare products, sunscreen, lotion, makeup, and hair dye. Ingredients beginning with methyl- may also be reaction-causing preservatives.
  • Fragrances: You'd be amazed by how many cosmetics and personal care products contain fragrances. Even if they aren't supposed to make you smell nice or are labeled "unscented," they may have a fragrance or fragrance masker. While there are at least 26 fragrance allergens as per Annex III of the European Union Cosmetics Directive, keep a special eye out for ingredients including "amyl," "benzyl," "cinna," or "extract" in the name. Several fragrances also contain benzyl alcohol, another potential allergen.
  • Medicated Topical Treatments: Medications are common allergens, and topical ones are no exception. Anything you put on your skin in hopes of taking care of a scrape, burn, or even an itchy rash can be an allergen itself—making the problem worse. Some common ingredients to look for are bacitracin, benzocaine, hydrocortisone, and neomycin.
  • Latex/Natural Rubber: Latex frequently appears in personal care and cosmetic products, and allergic reactions to this product can be more severe than many other allergens. It may be in applicators as well as the products themselves.
  • Dyes and Color Additives: Anything that adds color may involve dye, though you should mainly be aware of p-phenylenediamine (PPD) and coal tar.
  • Metals: Cosmetics and personal care products often contain metals, particularly nickel and gold, which can cause allergic reactions. Though lead can't legally be in cosmetics in the U.S., it can appear as a contaminant.

If you find you have reactions after using specific treatments or products, stop using them and bring the container (or a photo of its ingredients) to your doctor so you can work together to pinpoint your allergens.

Additionally, you may find you have allergic reactions to different types of jewelry and cloth. So, be mindful of your entire beauty regimen, not just your cosmetics!

How to Treat Skin Allergies

Many skin allergies can be treated at home without a doctor's intervention. However, speaking to a doctor before beginning any treatment regimen can help ensure you're making the safest possible choices.

Doctors may recommend allergy shots to build up immune resistance or prescription interventions. Or they could determine your reactions don't require that level of treatment and suggest some self-treatment alternatives.

You can also try these at-home options for treating skin allergies if you know you're not in immediate danger (i.e., you're breathing easily and not in debilitating pain) and are awaiting a doctor's visit. Remember, not every treatment works for everyone, and anything can be an allergen, so stay vigilant!

  • Antihistamines: Antihistamines are usually the first thing given to a person having an allergic reaction. Benadryl is probably the best-known antihistamine, but there are many on the market, including non-drowsy options.
  • Anti-Itch Cream: Hydrocortisone and calamine lotion are made expressly to relieve itching.
  • Bathing: The moment you realize you came into contact with a skin allergen, wash the affected area with a safe soap. If your allergic reaction seems widespread, jump in the shower. Moisturize after bathing.
  • Changing Products: If you know what caused your allergic reaction, stop using it immediately. If you're unsure, be aware of what you use and what happens afterward. Keep in mind that ingredients that were okay yesterday may cause a reaction today!
  • Colloidal Oatmeal: You can soak the affected area in lukewarm water mixed with colloidal oatmeal or use a cream containing this ingredient.
  • Cooling the Area: Rinse the affected area with cool water, use a cool compress, or take a cool shower to help calm the inflammation.
  • Minding Your Clothing: Tight, restrictive, or rough clothing (like denim) can rub skin allergies and further irritate them. So, try to wear baggy clothing in natural fabrics if possible.
  • Moisturizing: Using lotions or creams you know are safe after bathing or washing your hands or face can help keep allergies at bay.

How to Prevent Skin Allergies

As the cliché goes, an ounce of prevention is worth a pound of cure. While skin allergy prevention may take a lot of time and work upfront, it can save a great deal of worry, pain, time, and money on doctor's bills later. We can't control everything we come into contact with, but we can control many of the cosmetics and personal care products we use. Here's how.

Read Labels

Even if you don't currently have skin allergies, reading labels for common allergens can help prevent allergies from arising and keep sensitive skin safe. Watch out for anything containing formaldehyde, parabens, latex/natural rubber, metals, and fragrances.

Learn About Toxins

Toxic cosmetics contain dangerous products, whether intentionally or otherwise, many of which can lead to skin allergies and reactions. Labels may or may not list these toxins, but some cosmetics are more likely to contain unlisted toxins than others. Knowing what to buy can help prevent reactions.

Read Product Reviews

Before purchasing a product, even one that seems allergen-free at first glance, read product reviews to see if what the product claims and what people experience or have discovered are the same. You may find a common thread of reactions to a product that can alert you to potential issues.

Research Databases

Several online databases can help you research a product before you try it on your skin. For example, Environmental Working Group's (EWG) Skin Deep database lets you search by product name, then gives you detailed information and rankings on ingredient safety. Along with overall allergy risk, EWG provides ingredient-by-ingredient explanations of toxicity and allergy concerns.

Replace and Rotate

As you become more familiar with allergens in your hair and skin care products, start to replace your current products with safer options. Also, consider rotating them often, so you don't begin to develop sensitivities to any one item.

Try a Patch

If you have sensitive skin, set up your own patch test by applying a small amount of any new product to the inside of your arm a couple of times a day for two days. If you have no rash, redness, or other reaction after 24-48 hours, then you should be okay to apply it to your face and body.

Keep Things Clean

Keep the area where you store your cosmetics clean so nothing gets cross-contaminated with allergens. Similarly, keep your makeup brushes and applicators clean and throw away old cosmetics regularly.

Switch to Natural Deodorants

Traditional deodorants and antiperspirants often have aluminum compounds, which can cause redness, peeling, and itching if you're allergic to them. Aluminum-free natural deodorants can help you stay fresh without irritating metals.

Choose Fragrance-Free

The FDA does not require companies to detail specific fragrance ingredients—they can simply list "Fragrance" on the label. This means that any number (even hundreds!) of natural and chemical synthetic ingredients may make up a product's unique smell, and there's no way of knowing what's in it. While you could try different "fragrances" to see which ones cause reactions and which don't, it's not worth the risk! Instead, opt for fragrance-free options or products that use single-ingredient scents.

Aim for Water-Based Moisturizers

Emollients, which can include popular products like coconut butter to more mysteriously named ones like myristyl lactate, make your skin feel soft—but they also are more likely to cause allergic reactions (or at least breakouts) than water is.

Go Organic

Organic and natural products often contain fewer toxins, particularly sulfates—major culprits of allergic reactions. However, natural or organic products can still be allergenic.

Lose the Essential Oils if You're Sensitive

They may be natural, but so is pollen—and just as some people react to pollen, some people react badly to essential oils. If you're reacting to something containing an essential oil, switch to a version that doesn't contain that particular oil and see if it causes any reactions.

Get an Allergy Test

If you do all this and still have allergic reactions, go to the doctor and ask for an allergy skin test. Since you're probably looking for just a few ingredients, a doctor may prescribe a patch test, which focuses specifically on contact dermatitis causes. However, if you have many allergies or severe allergic reactions, they may opt for skin prick or injection tests.

Ease Off the Cosmetics

There's nothing wrong with loving makeup and hair products, but for your skin's sake, consider using less. If you're making a quick run to the store, for instance, perhaps you can go makeup-free! No matter what, be sure to remove makeup at the end of the day. Also, avoid spraying fragrances directly onto your skin and apply them to your clothing instead to avoid skin contact.

Use This, Not That: Substitutes for Commonly Allergenic Ingredients

For nearly every toxin or ingredient you're allergic to in cosmetics and personal care products, there is at least one healthier alternative ingredient that may be less likely to give you skin trouble. Here are just a few commonly used swaps.

Aluminum Magnesium Oil

Aluminum is frequently used in deodorants to reduce sweat, but it's also a common cause of underarm allergic skin reactions. Products with magnesium oil, or just the oil itself, can be very effective as deodorants and antiperspirants.

Methylisothiazolinone (MIT) Grapefruit Seed Extract, Essential Oils, Vitamin E

Like parabens, MIT is used as a preservative to prevent microbial and bacterial growth in beauty products. However, this neurotoxin is responsible for allergic reactions. Natural preservatives are generally much less allergenic and healthier for the body.

Petroleum-Derived Colorants Plant-Derived Dyes and Mineral Pigments

Artificial colors, which may also contain coal tar and heavy metals, can lead to allergic reactions and skin irritation. Avoid "FD&C" or "D&C" followed by a number on product labels. Plant-based dyes, like beet coloring, provide rich color without the risk of serious allergic reactions.

Petroleum Jelly/Petrolatum Unrefined Coconut Oil, Jojoba Oil, Cocoa Butter, Shea Butter

While petroleum jelly may cause skin allergy issues for a good number of people, it's also a widely recommended treatment for eczema. Fortunately, a variety of alternative ingredients can provide healthier moisturizing and protective properties.

Propylene Glycol Propanediol, Vegetable Glycerin

This moisturizer is common in many personal care products and is also used in anti-freeze and paint. For those who are allergic, it can lead to allergic contact dermatitis, including itching, redness, and swelling. Natural emollients and moisturizers provide much healthier and less irritating options.

Sodium Laurel/Laureth Sulfate Castile Soap, Soapwort, or Decyl/Coco Glucoside

These foaming agents are harsh cleaning ingredients that strip natural oils from the skin and cause irritation and allergic reactions. Natural and organic soaps and shampoos often have sulfate-free versions that are gentler on the skin and hair.

Synthetic Sunscreen Zinc Oxide

Chemical sunscreen ingredients—like oxybenzone, octinoxate, and avobenzone—can lead to hormonal disruption and are linked to skin allergies. Zinc oxide acts as a barrier to reflect harmful UVA/UVB rays.

The real challenge is that nothing is one-size-fits-all. Switching and swapping products until you find the right ones for you involves a lot of trial and error. If your allergies are severe, getting an allergist involved can help fast-track the process.

Best Products for People With Skin Allergies

When you start shopping for safe cosmetic products, there are a few words to look for right off the bat that indicate products may have fewer allergy-causing ingredients:

  • Sensitive Skin
  • Hypoallergenic
  • Fragrance-Free
  • Natural/Organic
  • Free and Clear
  • Baby

While not all safe products will have those words on the packaging, and not all products with the words are safe for you and your unique body, knowing these phrases lets you scan shelves a bit more easily. Before purchasing, read the entire ingredient label to ensure it doesn't contain any of your allergens.

Here are a few products that score a "low hazard" rating and have no or low allergy concerns, according to EWG.

Aveeno Skin Relief Body Wash

EWG Rating: 2

Aveeno created this body wash specifically for itchy and dry skin. This dermatologist-recommended product contains no fragrances, dyes, or soaps, but it does have eczema-soothing oatmeal. Amazon reviewer BLS titled their five-star review, "OMG, MY ECZEMA IS GONE!"

A reviewer writes, "This really helps with my daughter's eczema overnight by easing the itch and making the patches way less noticeable. We use this after EVERY bath!"

Free & Clear Hair Styling Gel for Sensitive Skin

EWG Rating: 1

Many hair styling products contain chemical irritants that can lead to allergic reactions. Free & Clear (from sensitive skin care company, Vanicream) is free of fragrances, dyes, formaldehyde, parabens, and lanolin. "Since I started using it no more acne and contact dermatitis like I would get from other hair gels on the market. This has been the only product that works for me. It has been a life saver and liquid gold!" says Free & Clear user, Hazel.

Neutrogena Hydro Boost Gentle Cleansing Lotion for Sensitive Skin

EWG Rating: 2

This fragrance-free cleanser removes makeup and moisturizes without many of the harsh chemicals and allergens in other products. "It is a very gentle, hydrating cleanser that is perfect for my dry, sensitive skin," says a reviewer. "I absolutely love that it is fragrance-free because I can only use fragrance-free products on my skin."

Schmidt's Sensitive Skin Deodorant Stick, Fragrance Free

EWG Rating: 1

Free of aluminum, baking soda, parabens, and other allergens, this fragrance-free natural deodorant not only fights body odor all day long but is much gentler on the skin than traditional deodorants. A happy customer writes, "I have extremely sensitive skin and have tried many different types of natural deodorant/antiperspirants. Either they didn't block the odor or I'd still have an allergic reaction. But this has worked wonderful and the stick lasts a long time."

The Honest Company Purely Sensitive Honest Face + Body Lotion

EWG Rating: 1

This fragrance-free lotion is perfect for all ages for head-to-toe moisturizing. Fast-absorbing and hypoallergenic, it's also free of many common allergens and irritants, including dyes, silicones, and parabens. An allergy-prone reviewer explains, "I love it and have gifted it to both my Mom and Aunt. Unfortunately I cannot have any scent (I break out in hives) so I go with the Purely Sensitive which works great and does not give me hives."

The Honest Company Shampoo + Body Wash, Purely Sensitive Fragrance Free

EWG Rating: 1

Formulated for babies but effective for all ages, this gentle preservative-free shampoo and body wash is ideal for eczema, dry skin, cradle cap, and other sensitive skin conditions. "I recently found out that I'm allergic to fragrance," writes one customer. "I had to change all my products I use daily to fragrance-free. This shampoo lathers very well and has absolutely no smell whatsoever!"

Sometimes, sensitive skin products can be a bit pricey—though not universally. So, if you're comparison shopping, look for labels reading "compare to [brand/product]" and double-check for ingredient accuracy before making the cheaper choice.
