Patch Testing

At Medik8, we always recommend performing a patch test before incorporating any new product into your skincare routine.

What is a patch test?

Although relatively rare, reactions from allergies and sensitivities to certain ingredients in any skincare product can occur. Patch testing gives peace of mind that a new product is suitable for your skin. Apply a small amount first to check for any adverse effects, before regular use.

NOTE: We cannot rely on patch tests alone to prevent all potential reactions, as they do not guarantee that similar results will be observed when the product is applied to other areas of the body, such as the face. It’s therefore important you follow the product’s usage directions and precautions carefully.

Patch testing will not account for underlying conditions and should not be used to diagnose hypersensitivity or allergic contact dermatitis, unless under the supervision of a doctor. If you have any concerns, please contact your doctor or dermatologist for advice.

If you do experience any form of excessive irritation during your patch test, please contact our Customer Care team: hello@medik8.com

FAQs

How do I patch test more than one product?

You can patch test up to 2 products at a time. Place the 2 products on either arm, and make a note of which side you have applied each product to. Therefore, if a reaction does occur, you will know which product is responsible for the reaction.

How frequently can I conduct patch tests?

After conducting a patch test, leave at least 3 days before attempting another on the same area of skin. This helps to avoid confusion of results.

How do I patch test a deluxe sample?

You can patch test our Deluxe Samples the same way as you would patch test a full size product.

How do I patch test Ultimate Recovery Bio-Cellulose Mask?

Because Ultimate Recovery Bio-Cellulose Mask comes in a sachet, it cannot be left open for an extended period of time. A shorter patch test is therefore required for this product. Rather than waiting for 24 hours after your patch test to use this product, wait 1 hour and observe your skin’s response. 1 hour is long enough to display the first signs of any potential reactions. If no such signs are present, you can use the product as per its directions. <br><br>

<b>NOTE:</b> A shortened exposure time may not be long enough to display all potential allergic reactions.

Are Medik8 products safe for use on my skin?

All of our products are completely safe for use on the skin, having undergone extensive testing and assessment by an independent safety assessor. However, allergies and sensitivities to certain ingredients within any skincare product can occur. With increases in the amount of products people use within their daily skincare routines, we always recommend patch testing as best practice before trying a new product.
