Does a designer stubble stay on the face if you use a 1mm guard?

Yes, a designer stubble can be maintained with a 1mm guard on a trimmer. This guard length will help to keep the stubble at a consistent length and prevent it from growing too long. It is important to regularly trim and maintain the stubble to keep it looking neat and well-groomed.

A 1mm guard would create a very short stubble that would be barely noticeable. It would not be considered a designer stubble. If you want a designer stubble, it is recommended to use a guard of at least 3mm.
