During a gel polish procedure, if the client feels heat, what type of reaction does this indicate?

The correct answer highlights an important aspect of chemical reactions during a gel polish procedure. An exothermic reaction occurs when heat is released as a result of a chemical reaction taking place. In the context of gel polish, the curing process involves a chemical reaction when the product is exposed to UV or LED light. This reaction releases heat, which the client may feel as the gel begins to harden.

Understanding that the sensation of heat is linked to the exothermic nature of the reaction is crucial for nail technicians. When performing gel polish applications, it is essential to monitor the client's comfort and explain any sensations they might feel, such as warmth, to enhance their overall experience and ensure they know this is a normal occurrence during the curing process.

The other types of reactions mentioned, such as endothermic, refer to processes where heat is absorbed rather than released, which would not apply in this instance. Additionally, categorizing the reaction as physical incorrectly suggests that no chemical change occurs when the gel cures, which is not accurate since a chemical transformation is essential for the gel to solidify.
