An ultraviolet violet exposure profile for the subject person is generated based upon the data and a health assessment report provided. The data may include timestamped images of the subject person and other related persons. The skin characteristics within images are analyzed to determine an ultraviolet light exposure level for the subject person from each image. The skin characteristics may include skin color, freckling and blemishing. The ultraviolet light exposure profile may be developed over an extended interval based upon the image timestamps. The health report may be used to mitigate risks, such as skin cancer, associated with exposure to ultraviolet light.
