What is a key benefit of using warm lather in shaving?

Using warm lather in shaving is beneficial because it helps open the pores of the skin. When the pores are open, they allow for better access to the hair follicles, which can make the shaving process smoother and more effective. This results in a closer shave and can help reduce irritation, as open pores can lessen the tugging and pulling on the skin during the shaving process. Moreover, warm lather can soften the hair, making it easier to cut, which contributes to an overall improved shaving experience.

The other options do not accurately describe the primary benefits of using warm lather. It does not cool the skin; in fact, warm lather does the opposite by creating a soothing effect. Additionally, while there may be some numbing sensation from warmth, that is not its primary purpose, nor does it prolong the shaving process, which is typically associated with an efficient and effective shave. Thus, the key benefit of using warm lather is indeed its ability to open the pores, facilitating a better shave.
