The Phi Patch Test is a method to determine if a substance that comes into contact with the skin (a product used during treatment) causes any kind of skin reaction. Any cosmetic pr oduct can cause skin reactions in certain people. Possible reactions include redness and itching at the application site. This product allows you to determine in advance whether a cosmetic product may cause irritation, so that you can avoid using such a product. It is not recommended for clients taking cortisone/prednisolone or immunosuppressive medications as the results of the test may be invalid. Show more
