What is the purpose of using a cold towel during a shave?

Using a cold towel during a shave primarily serves to soothe the skin and reduce inflammation. A cold towel can help alleviate any irritation that may arise during the shaving process by constricting blood vessels, which in turn minimizes swelling and redness. This cooling effect is beneficial after the application of heat from a hot towel or warm lather, as it can help balance the skin and enhance comfort.

Additionally, the application of a cold towel post-shave can provide a refreshing sensation, making the overall shaving experience more pleasant. It's also important to note that while skin preparation and blood circulation are relevant factors in the shaving process, the primary function of a cold towel leans more towards immediate post-shave skin care, focusing on soothing effects rather than preparation or circulation enhancement.
