What is a common component of facials that promotes muscle relaxation?

A hot towel treatment is indeed a common component of facials that promotes muscle relaxation. The use of warm towels on the face helps to soothe the muscles and promote circulation. The heat from the towels can relieve tension in the facial muscles, making it an effective method for encouraging relaxation during a facial treatment.

While hot stone therapy can also promote relaxation in massage settings, it tends to focus more on deeper muscle tissue as it involves the use of heated stones rather than directly addressing the facial muscles. Cooling gel application serves to refresh or calm the skin, and face masks primarily focus on skin treatment rather than muscle relaxation. Thus, the warmth and comfort offered by hot towels make them particularly effective for promoting a relaxed state during facial treatments.
