Why is it vital to patch test products before applying them to the face?

It is vital to patch test products before applying them to the face primarily to check for allergic reactions. The skin on the face is generally more sensitive than skin elsewhere on the body, which makes it prone to irritation or allergic responses from certain ingredients in skincare products. By performing a patch test, you can identify how the skin reacts to a specific product and determine if it is safe to use on the more delicate facial area.

Conducting a patch test helps to mitigate the risk of adverse reactions that could lead to redness, swelling, or other forms of irritation, allowing for a safer and more effective application of products on the face. This precautionary step not only protects the client's skin health but also enhances the overall client experience by preventing uncomfortable side effects.
