People can be allergic to all kinds of materials and ingredients, whether it’s natural materials like pollen or synthetic materials like certain types of plastic. When you’re using a new skincare product, it’s important to patch test it first to make sure you’re not allergic, because not every product works for every face.  Keep reading to learn how to patch test skincare!

 

 

What is a Patch Test?

A patch test is a simple way of checking whether your skin will react to new products such as cosmetics, soaps, moisturizers, or topical medications. Patch testing is a common way to check for a variety of allergies. This test is often ignored and can result in acne or allergic reactions, so please remember to patch test a product because not every product works for every face.

  

 

How to Patch-Test a Product

Patch testing is simple. Just keep in mind that you’ll need to set a day aside if you want to do your patch test properly. Follow the steps below.

 

1. Use a Clear Patch of Skin

Choose an accessible and clear patch of skin to test whatever the product is. It should be somewhere that you can comfortably leave alone for up to 24 hours. The skin around the crook of your elbow, behind your ear, or your wrist are a few examples of the kind of areas you can use.


2. Clean the Application Area First

Wash and clean the patch of skin you’re going to apply the new product on first. If there is a reaction, you will want to be sure that it’s the new product you applied and not something else. So, make sure to clean the area before you begin.


3. Apply a Small Amount to the Skin

Grab the new skin care product you want to test! To keep it contained to a specific area, consider applying it to your skin with a cotton swab and apply a SMALL amount onto the skin.  
Just remember to apply the product on enough surface area that it allows you to notice a problem should one arise, but small enough that it won’t be detrimental if something does go wrong.


4. Wait 24 Hours

Now it’s time to wait. You should ideally allow the new product to remain on your skin for about 24 hours. However, if you experience any pain, burning or itching, you should remove the product and wash the affected area right away!

 

 

Not All Reactions Are the Same. What to Look For

 

There are two main things that you are testing for: Irritation and Allergic Reactions. If you’re allergic to the product it should be pretty easy to tell.

These reactions can manifest as a variety of ways—reddening, dryness, itching, peeling, burning, blistering, and swelling. All bad, right? Basically, it's when your products are making your skin worse, rather than better If the skin is red, raised, itchy, or covered with a rash, then it is likely you have a severe allergy to the product.

The first thing to look for is an irritant contact dermatitis, which happens quickly—within minutes to hours of exposure.

The second is an allergic contact dermatitis, which takes repeated exposure to the product and days to develop—at least 4 days.

Keep in mind that you may not be allergic to a product if you’re simply having a reaction to it. And if you’re experiencing a reaction and yet there is no new product in your regimen, it could be a slow-build response. Similarly, you might experience a reaction because of one-off factors.

If you’re not sure, or if you’ve had severe reactions to skincare products in the past. It is always a good idea to talk to your doctor or an allergy specialist.
