How is skin sensitivity tested before using tanning products?

Testing skin sensitivity before using tanning products is appropriately done by applying a small amount of the product on a patch of skin. This method allows the consultant to directly observe any immediate reaction the skin might have to the ingredients in the product, such as irritation or an allergic response. This practice is especially important as it helps identify any adverse effects that might not be apparent through other means.

Asking the client about their skin type can provide context regarding how their skin might react to tanning products, but it does not replace the need for an actual sensitivity test. Similarly, conducting a full body inspection and analyzing past tanning experiences can be beneficial for understanding the client's overall skin health and history but do not specifically determine sensitivities to the products being used. The patch test is the most definitive way to ensure the product's safety on a client's skin.
