Which is NOT a primary advantage of using hot towels in facials?

The primary advantages of using hot towels in facials are related to enhancing relaxation and promoting overall skin health. Hot towels help to enhance blood circulation, which can lead to improved skin tone and more efficient nutrient delivery to skin cells. They also work to relax facial muscles, contributing to a calming effect during the facial treatment. Additionally, hot towels can soothe inflamed skin, providing relief and making the skin feel more comfortable.

Stimulating excessive sweating, however, is not considered a primary advantage of using hot towels. While the heat from hot towels may induce some sweating due to elevated temperature, this is not a desired or beneficial outcome during a facial. The focus is typically on promoting relaxation, circulation, and soothing effects rather than excessive perspiration, which could lead to dehydration of the skin or other unwanted effects.
