A hand model is a person who models their hand or hands for the purposes of art, fashion, products or advertising. Hand models are used in advertising where advertisers want close ups of the product being handled. Most hands have blemishes such as scrapes, scars, spots, or discolorations which would stand out in a close up and detract from the product. Hand models tend to have flawless skin and hands. In female hand models agents often seek long, slender hands and fingers and long nail beds. They also value smooth, hairless, unblemished skin with minimal wrinkles and visible pores.
