A facial composite is a graphical representation of one or more
eyewitnesses' memories of a face, as recorded by a composite artist. Facial composites are used mainly by police in their investigation of (usually serious) crimes. These images are used to reconstruct the suspect's face in hope of identifying them. Facial reconstruction can also be used in archeological studies to get a visualization of ancient mummies or human remains.
Methods
Hand-drawing
Construction of the composite was originally only performed by a trained artist, through drawing, sketching, or painting, in consultation with a witness or crime victim.

claims that hand-drawing is its preferred method for constructing a facial composite.
Feature-based selection
Feature-based systems essentially rely on the selection of individual features in isolation. Individual facial features (eyes, nose, mouth, eyebrows, etc.) are selected one at a time from a large database and then electronically 'overlaid' to make the composite image. This allows images to be created when suitable artistic talent is not available.
Such systems were originally mechanical, using drawings or photographs printed on transparent
acetate sheets that could be superimposed on one another to produce the composite image. The first such system was the drawing-based "Identikit" which was introduced in the U.S. in 1959.
A photograph-based system, "Photofit", was introduced in the UK in 1970.
Modern systems are software-based; common systems include SketchCop FACETTE Face Design System Software, Identi-Kit 2000, FACES,
E-FIT Electronic Facial Identification Technique (E-FIT, e-fit, efit) is a computer-based method of producing facial composites of wanted criminals, based on eyewitness descriptions.

Welker Facial Reconstruction Technique
This technique was created in order to determine the depth of human face tissue.
Welker, was able to measure the depth of human face tissue by inserting surgical blades throughout different areas of the face.
He was able to map out the areas of the face that had the most tissue depth.
In the 1880's to 1890's a man named Wilheim was able to further advance the Welker Facial Reconstruction Technique.
He used thinner needles to achieve a more targeted and precise measurement of depth, rather than using a bulky surgical blade that can distort the surrounding tissue.

Evolutionary systems
Evolutionary systems may be broadly described as holistic or global in that they primarily attempt to create a likeness to the suspect through an
evolutionary mechanism in which a witness's response to groups of complete faces (not just features) converges towards an increasingly accurate image. Introduced in the 2000s, such systems are finding increasing use by police forces.

While the classic use of the facial composite is the citizen recognizing the face as an acquaintance, there are other ways where a facial composite can prove useful. The facial composite can contribute in law enforcement in a number of ways:
