The direction of the lighting can emphasize or minimize the appearance of acne and scars, too. If you have raised bumps or crater-like scars, light that's coming from the side will make uneven highlights and shadows on them, making them much more noticeable. (related: partial-moon photos are often much more interesting than full-moon photos, as the directional lighting will emphasize the hills and craters, whereas the flat lighting on a full moon will not)
If it's worst on your forehead, point your face toward the light, and the appearance of those imperfections will be minimized - however, this may emphasize imperfections on the sides of your face. Of course, don't get bogged down and refuse to ever vary your pose, just be mindful of how the light affects your features.
In any case, it's not too much effort for an experienced photographer to smooth out acne.
For photographic purposes, I prefer that subjects NOT go too crazy in trying to cover up acne and scars with makeup (pro-level makeup skills excepted). It's way easier to retouch one little 1/8"-diameter bump, instead of a 1/2"-diameter blob of off-color makeup where the subject tried (unsuccessfully) to hide the imperfection.
