Freckles often occur in exposed areas and are determined by environmental factors. Sun exposure is an important external condition for the formation of freckles, and the ultraviolet rays in sunlight can make the activity of tyrosinase in some melanocytes more active, so freckles are related to the season, with more and darker colors in summer and less and lighter in winter.
