A review with 130 references covering photochemical damage caused by UV rays in collagen. The damage is known to be related to collagen type and age, and to the nature of the admixtures present in collagen, but the mechanism of the damage has not yet been fully recognized. Collagen's chemical structure is discussed in detail to present collagen properties of various collagen types before and after collagen has been UV-irradiated.
