Hand dermatitis, also called fu kuei shou, is a skin condition in which the hands develop a rash and become red, dry, cracked, and inflamed. This is a very common occuring in about 10% of women and 4% of men. The condition can eventually cause pain on contact with even simple solutions such as water. Hand dermatitis is particularly common in industries involving cleaning, catering, metalwork, hairdressing, healthcare and mechanical work, and is often difficult to be treated effectively. Some patients develop varying levels of disability due to lack of acceptable effective treatments and may be forced to change occupations in order to achieve relief.
