How To Do A Patch Test?

Nowadays, using makeup and skincare products has become common among men and women. But before using any product, they need to test if the product suits their skin condition. For example, some people might be allergic to specific components present in skincare products. Applying them on the face without conducting a patch test might result in severe allergic reactions. Performing a patch test can resolve several issues and use the product without worrying about the quality. 


What is patch testing?

Patch testing is an approved dermatitis diagnostic tool that is used for determining the allergies of a person. During this procedure, specific patches made up of the allergens are applied to the skin of the person's body to analyse their allergies. But the scientific technique mentioned above can be hectic for normal people, and they can conduct the test by themselves at home. The test can also be performed at home by applying the products you wish to test on your wrist and back of the ear. For example, some skin products can be tested on your wrist, and certain hair care products can be tested on the space behind your ears. These are the least exposed parts of your body and

Detecting if you are allergic to the skincare product.

Things to note before patch testing

Before performing a patch test, there are certain things that you need to consider. Understanding them will allow you to perform a regular test without any interruptions in the middle.


What type of skin condition do you commonly face, like breakouts or clogged pores?

Which part of the face is more likely sensitive and receives such inflammations and breakouts?

Which part of the face can easily show symptoms like redness and sensitivity?

How long does it take for the skin to react to any allergens?



All these details are necessary for performing a patch test. 


How to do a patch test by yourself?


There is not a single way to perform a patch test, and hence we have given one of the most common procedures that are followed regularly in the medical field. Most of the time, this type of test will work out for you, and if not, you can try any other difficulty with the help of a dermatologist. 


Wash the area that you are trying to test with plain water. Choose a site that is not available for plain sight. 

Apply the product to the wrist or behind the ear area and wait for the reaction to appear. This test can be conducted for up to 15 minutes. 

If you are using a washing product, then wash away the surface after 15 minutes; otherwise, wash it away after some time. 


Wait for at least 24-48 hours to test if the product works or not. During this time, observe the symptoms to identify if the skin is purging or breaking out. Purging is considered a good sign since it means that the skin reacts to its contents. But breaking out is not a good sign, and if it occurs, cleanse the skin and consult a doctor. The patch test should be conducted gradually in the least problematic area and slowly moved towards the most challenging area. If there is any type of irritation, it is off immediately, especially in a complete face patch test. 


What to do in case you react?


Sometimes, when you perform the test, you might experience itchiness, redness, inflammation, breakouts, and blisters. If you experience any of these symptoms, stop using the product and immediately wash the place with an attested cleanser and moisturiser. Apply some of the soothing gel products like aloe vera and rest for a bit until the skin turns normal. 


This is a simple test that can improve your skincare experience with a wide range of products. Anyone can try the patch test at home, but you must immediately check any reaction you cannot control with a doctor.
