Once applied, the wax is left to cool and harden, and then quickly pulled off, taking the hair with it. This method of hair removal is often used on larger areas of the body, such as the legs, arms, back, and chest.

However, it can be painful and may cause skin irritation, redness, or even burns if not done correctly.
