How to patch test skincare product the right way

Are you the one that run home immediately after buying a brand new spanking toner to slather it on your face? Well, we can understand the excitement of trying it out immediately, however we couldn’t stress enough on patch testing your new product to check if you would have any adversed reaction to any ingredient in the product.

Just because you don’t think you have sensitive skin or reaction (yet), doesn’t mean that you might not be reacting to any active ingredient that are strong. While a lot of products are dermalogica tested with proven results, does not mean that you are safe of any reaction.

Studies shown that there are at least 2% of the world’s population that are prone to some reaction. This could be you.

Remember, some products have strong active ingredients to target certain areas of skin concern and that truly work for you if you do not have any skin reaction. However, if you do, your skin may turn red, inflamed or even flake.



How to patch test.

Allergic reactions.

Apply the product in question behind your ear.


Apply where you have higher chance of reaction. Mostly cheek or chin.

Pore Clogging or Breakouts

Apply on areas where you have most zits, breakouts or clogged pores. Highest possibility are areas around chin and T-Zone.

How long to patch test a product?

We recommend to patch test for at least 3 days.

Usually, you’ll see your skin reacts to a product within 24 hours. However, some with more resilient skin may take up to few days before seeing any negative result.


A lot of natural products used active botanical ingredients to target specific skin concern, example anti-aging, moisturising and so on. In such cases, the active ingredients may be just a tad bit too strong for sensitive skin.

Having an allergy reaction to a specific product does not mean the product is not good enough for skin or the entire brand’s product are bad. Remember, whilst you may have some reaction, that doesn’t mean others have it (you may fall in that 2%). It truly depends on individual’s skin tolerance level.

Any reaction to a product should be noted down, so you’ll know what ingredients to avoid in a product on your next purchase.

Hopefully the above tips helps you in patch testing your products.
