What is a common issue with loose skin during shaving?

Loose skin during shaving tends to push out in front of the razor, which can result in an uneven shaving surface. This is particularly problematic because it can hinder achieving a close and smooth shave. When the skin is not taut, the razor may catch on the loose skin rather than glide smoothly over it, leading to potential nicks and cuts. Maintaining tension in the skin while shaving is crucial for achieving an effective and safe shave, ensuring that the blade can make proper contact with the hair without interference from the skin's movement.

The other choices do highlight different concerns associated with shaving, such as the possibility of skin irritation and restriction of razor movement, but they do not directly address the specific issue associated with loose skin pushing out in front of the razor. Therefore, focusing on keeping the skin taut is essential for a better shaving experience.
