Why is it important to patch test The Ordinary?

It’s really important to patch test The Ordinary products in case of any irritation or allergic reactions. After all, you are using them to hopefully improve your skin, not make it worse. Once you know your skin is ok with these ingredients, you can continue to use them safely in your routine and then start to layer them. As you start to layer The Ordinary, continue to pay attention as to how your skin looks and feels and make sure you are not using any that conflict.

I’ve never had an allergic reaction before, do I really need to patch test?

There´s always a first! If you have never had an allergic reaction before and never patch tested anything, you may think you will be absolutely fine slapping on loads of The Ordinary products all over your face. You might be absolutely fine but then again, you might not be. Allergic reactions can happen to anyone. They can be really painful, take a lot of time to heal and cause damage to your skin. It´s better to be safe than sorry.

Does everyone patch test The Ordinary?

The truth is the majority of people do not patch test products. I ran a poll in Instagram Stories (I will try to find it) and the results were something like 75% of people did not patch test. So why don’t people patch test?

  • Because they´ve never had a reaction before so they think their skin can tolerate anything.
  • People get excited when they receive all their skincare goodies and just want to apply them all.
  • Some people watch their favorite influencers on Instagram, Tic Tok, YouTube and just follow what they say and do rather than read the instructions. Please don´t do this!
  • Because it´s not something people do. Do you patch test every piece of makeup you apply to your face?

The Ordinary Allergic Reactions That Made The Headlines!

Here are some stories about The Ordinary Salicylic Acid that made the headlines. This product is currently being reformulated but I think it’s important to share with you that 74% of the Deciem Addicts absolutely love this product and cannot wait for it to be back in stock.

These stories are terrible and their skin looks awfully painful. I really hope their skin has recovered well. It´s important to bear in mind that we do not know if patch tests were carried out correctly, if the product was used on compromised skin, or anything else that could have caused such a reaction. This product can cause chemical burns which is why it should be patch tested and then spot tested before applying all over the face. Please always read the instructions before using.

Allergic Reactions To Skincare, Sun Cream, Perfumes – anything!

People have allergic reactions all time but rarely do they make the headlines. I’ve personally had reactions and a burns from sun creams by La Roche Posay, Frezyderm and a Kiehls product. I was very unwell with a Jo Malone room diffuser and also the Zadig & Voltaire perfume for women. Deodorants with aluminum are now a complete no go area. I suddenly had a terrible reaction with a hair dye I had used for years but it was actually the powder inside the plastic gloves. Whilst I have a lot of allergy issues, I´m pleased to say I have never had a reaction to The Ordinary.

Videos about skincare products – irritation & allergic reactions

Here’s a really informative video all about skincare irritation and allergic reactions with Dr. Sam. In the unfortunate event that you do suffer a reaction or irritation please remember to patch tests any products that have been recommended to repair your skin. Just because these are “repair” products or specially designed for sensitive skin, doesn´t mean you will not have a reaction with these.

A quick recap – How to use The Ordinary safely

  • Patch test, patch test, patch test!
  • Read the instructions on the official The Ordinary page before using them.
  • Always check which products you can and cannot use together.
  • If you are having any treatments like laser, botox, microblading etc speak to the professional who is doing the procedure and ask if you should avoid using certain ingredients before and after. When I had micro blading I was told to avoid acids and retinol for a week beforehand and a few weeks after.
  • Some of these products can cause skin sensitivity so direct sun should be completely avoided.
  • Use a good SPF every day! This really is the most important step in your skincare routine.
