A clean and well-groomed beard area can make a significant difference in the overall appearance, adding a dash of confidence and definition to your jawline. However, so many men typically mess with their facial hair in their own bathrooms as a necessity, and then it becomes a rescue mission. To get that perfect symmetrical balance, more than a steady hand and a sharp razor is needed. Once you know what you’re doing wrong, it takes no effort at all to keep your facial hair clean and professionally finished every day.
Shaving Too Far Above the Adam’s Apple

It can be difficult to find the right edge for your neck environment. One of the common mistakes is cutting the neckline too high, which is a very common thing to do and will definitely give the impression of an odd double chin, even if the shape is lean.
Freehanding the Symmetry Without a Plan

If you don’t have a clear visual plan when you start a trim, then you can expect lopsided results. Men will start shaving one side to make it even with the other, then thin it down further and so on, until there’s nothing left.
Using the Wrong Trimmer Blade Guard

The wrong size of guard can ruin weeks of painstaking growth. There are differing lengths of zones that must be used for different faces to be harmonious, and a common setting will often make the face appear to be very flat.
Neglecting Pre-Shave Skin Preparation

Attacking dry skin with a blade will only bring with it redness and lines. Without a warm rinse or good pre-shave oil, the trimmer could pull on the hair follicles, causing uneven edges and possible redness all over the cheeks.
Trimming While the Hair Is Wet

Facial hair undergoes a great deal of relaxation and stretching when moistened. When wet, map out the boundaries, and then when dry, the hairs will spring back, and the outline will become so irregular that you will have a perimeter that is much shorter than you intended.
Forgetting to Define Your Natural Cheek Boundary

If you make the upper cheek line too steep and point downwards, you change your face’s natural shape. Generally, it is better to have your hair follow the curve where it is densest, not such a dramatic curve that appears too fake.
Overlooking the Value of Proper Lighting

The dark light in a bathroom is the biggest culprit for a crisp edge. The symmetry of your jaw is hard to assess without good, even light from every direction, and often the result is that the two sides don’t match, which only becomes apparent when you are outside.
Using Blunt or Rusted Blades

The steel drags in the hair rather than cutting through it. This is because the lack of sharpness results in unnecessary pressure being applied, often leading to the tool slipping and creating a flawed perimeter in an instant.
Letting the Mustache Overlap the Lip

A shaggy mustache will immediately make an impeccable lower face look messy. If the upper lip has some stray hairs that have slipped over the frame, it will not create a crisp, intentional look that the frame is supposed to give.
