Fingerprints serve to Although scientists agree that fingerprints begin to develop around the 10th week and are complete by the end of the 4th month, no one is certain of the precise process that creates them. One theory holds that a middle skin layer, called the basal layer, is scrunched between the inside layer (the dermis) and the outer skin layer (the epidermis). Fingerprints are the tiny ridges, whorls and valley patterns on the tip of each finger. They form from pressure on a baby's tiny, developing fingers in the womb.

It can effectively remove the fingerprints on the screen, oil stains, etc., and leave After wiping, a protective film will be formed on the surface of the computer to

One theory holds that a middle skin layer, called the basal layer, is scrunched between the inside layer (the dermis) and the outer skin layer (the epidermis).

Though these epidermal ridges are found on fingers, palms and soles, they are popularly called just fingerprints.
