This is such an important skincare topic that’s too often avoided. Patch testing properly can go a long way in clearing acne, particularly for those suffering from “acne-cosmetica,” that is, comedones, pustules or papules caused by using products that are incompatible with your skin.
Remember to patch-test absolutely everything before incorporating it into your skincare routine or going full-faced.
Also avoid using a products if it contains a component you know you are allergic to.
What is patch testing?
Patch testing is a way of testing a new product to see if it will work for your skin and unfortunately this test is often ignored, and can result in pretty severe acne or allergic reactions.
Believe it or not, a lot of the problems you see above were simply caused by using the wrong things on my skin. If you have adult acne, there’s a very good chance your breakouts are product related. If you suspect this might be the case, stop using everything for at least two weeks and see if things subside.
How to patch test.
There are three different things to test for:
1. Allergic reactions.
Apply the product in question behind your ear.
2. Irritation.
Apply the product in question where you’re most sensitive. This will vary from person to person, for me it’s the corners of my nose and chin.
3. Comedogenicity (how pore-clogging something is).
Apply the product you’re testing to the area you experience the most breakouts and clogged pores. This will also vary from person to person. For me, it’s my chin and the space between my eyebrows.
How long do I need to patch-test a product?
Once again, this varies from person to person. It depends it may occur quite quickly or after few days.
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.
