We recommend to patch test new skin care products if you have sensitive skin or have had reactions to skincare products in the past.
To carry out a patch test, choose a clean and small part of your skin (eg behind the ear), apply a small amount of the treatment/product to the area and then observe the area for 24 hours for any reactions. If you experience any irritation, burning, pain or itchiness wash off the product. If you have no reaction, it should be safe for you to use but please apply slowly and cautiously the first few times of use.
