METHOD FOR DETERMINING AN INDIVIDUAL'S SUN PROTECTION FACTOR REQUIRED FOR PROTECTING SKIN

摘要

A method for determining individual sun protection factor required for protecting skin is provided to guide a usage and a selection of an ultraviolet protecting product based on a decided ultraviolet protecting factor. A method for determining individual sun protection factor required for protecting skin includes the steps of: deciding an individual's MED(Minimum Erythemal Dose); estimating an intensity of ultraviolet exposed to the individual; and obtaining a value computed by dividing the estimated intensity of ultraviolet by the decided MED.
