If you plan on going in the water (amphibious operations), get grease face paint so that it won’t come off.
If you are going out at night, you can simply paint your face black to blend in.
Make sure not to get any paint in your eyes! Exercise caution when painting around your eye area.
Instead of a medium green shade, use tan in a desert or grey paint in an urban or snowy environment.
Covering these areas with darker paint is important because it helps to flatten your face. When your face appears as a flat image, it is difficult to detect. [7] X Research source
In a temperate deciduous forest, use blotches; in a coniferous forest, use a broad slash; in a jungle, use a broad slash; in a desert, use a slash; in the arctic, use blotches; and in grass or an open area, use a slash. [10] X Research source
If you have a bald head, cover that as well. Use darker colors so that it doesn’t reflect sunlight. [11] X Research source
Although not very common, applying natural foliage directly on your face is a useful form of camouflage. This works best with the use of a ghillie suit so that your entire body is covered in vegetation.
You could also place a few long blades of grass behind your ear. If the foliage is not staying in place, you could pin, glue, or tape it onto your clothing. Just make sure the adhesive isn’t visible. Sticking a little mud on the foliage will also help it to stay in place. You could also buy a mesh mask and place foliage in the holes of the mesh. Just make sure not to cover your eyes, ears, or mouth with foliage.
The best camouflage will come from a mask with a realistic pattern rather than a standard color pattern in camo. The advantage of masks is that you can make your face look exactly like nature rather than just similar in color. If you are going out at night in a dark area, an all black mask will work well.
