Comb it downward, set the length on the body of the mustache first, and only then cut the lip line with the guards off, using the corner of the blade.
Two different jobs get confused here. The lip line is an outline and is cut with no comb. The bulk of the mustache is a length and is cut with one.
The order is the whole of it, and it is counter-intuitive: length first, outline second. Setting the length after the outline moves the outline — the bulk shortens, the hairs at the lip lift, and the line you cut yesterday is now in the wrong place. Doing it the other way round is what produces a mustache suddenly much shorter than intended.
Combing downward before the outline pass is what shows you where the lip actually is.
A detail trimmer, where a kit includes one, is far easier on this than the main blade — it is narrower and steers rather than sweeps. Two of the four all-in-one kits here publish one: the Philips MG7962 at $125 states a narrow detail trimmer, and the Braun AIO7565 at $165 a precision head. The pop-up trimmer on a shaver is the fallback. And five trimmers on the nose and ear shelf ship a separate brow or detail head for a fraction of either price — the Jeetif at $17 carries three interchangeable heads, which is the most on that shelf.
