Does the color of the skin determine the amount of sun protection needed?
Yes. The color of the skin as well as an individual’s geographic location determine the amount of sun protection needed. In general, the fairer the skin tone, the higher the SPF number required. In addition, the sun is stronger at lower latitudes and at higher altitudes (i.e. UV levels in Vail, Colorado are 60 percent higher than those in New York City. Consequently, stronger everyday protection is required in Vail than in New York City).
