Bella Glossary: Patch Test

Definition: The Patch Test

The Patch Test is something that you're likely to see on the back of products if you're someone who reads labels. Simply put, it's a fool-proof way to check and see if your skin will turn red, become itchy, or swell due to an ingredient in a beauty product.

Kiehl's is an advocate of the patch test and it's something I recommend to anyone with dry, highly-allergic, or sensitive skin. Apply a small amount of product (about the size of a dime) to your arm (preferably the underside of your forearm), cover it with a Band-Aid, and keep an eye on the area for 24 hours.

I know it seems basic, but it works. You know the old saying about an ounce of prevention, right? If you don't,

"An ounce of prevention is worth a pound of cure."

I don't usually do the patch test either...but, the other day I was getting ready to do the aspirin mask for the first time...and I wasn't going to do the patch test. But, I ended up doing it anways and it turns out I had a reaction to the aspirin. While the aspirin mask was on my arm, it started to burn and when I took the mask off, my skin was extra pink in the area. I'm soooooo glad I did the patch test before doing anything else!! I think, I'll be taking that extra precaution from now on.

I have sensitive skin, and I've tested products many times before using them all over, but I've never covered the area with a Band-aid. Didn't know I was supposed to, I'll have to remember that.

I've never had a reaction so I've never done a patch test. I know that the student salon where I worked while in Cosmetology school everyone needed a hair color patch test before they could get their hair colored.
