If you use a 1mm guard, does it keep the designer stubble on the face?

Using a 1mm guard will likely trim the designer stubble very short, but it may not completely remove it depending on the length of the stubble. It will give a very close trim and maintain a neat appearance, but it may not be long enough to achieve the desired designer stubble look. It is recommended to experiment with different guard lengths to find the one that best suits your desired style.

Yes, a 1mm guard will typically keep the designer stubble on the face. Designer stubble is a short, even beard that is typically 2-3mm long. A 1mm guard will trim the beard to a length that is short enough to look neat and well-groomed, while still leaving enough length to give the appearance of stubble.
