A normal reaction to sugaring might include:

A normal reaction to sugaring might include some itching, as the process of hair removal can irritate the skin. This can happen due to the tugging sensation when the sugar paste adheres to the hair and is pulled away from the skin. Mild itching can be a common occurrence as the skin adjusts following the treatment.

In contrast, excessive redness is typically associated with a more intense reaction and may indicate sensitivity or an adverse response, while severe swelling is usually a sign of an allergic reaction or more severe skin irritation, which are not expected in a normal reaction to sugaring. Nausea is not a typical reaction associated with hair removal processes, including sugaring, and would warrant further investigation into other underlying issues. Therefore, some itching stands out as a normal and expected response after a sugaring treatment.
