Have you noticed that the seeds or skin of strawberries are creating tiny black spots on your legs? The dark spots could be hair follicles, or pores that are enlarged. They could come from many different causes that include bacteria, dead skin and oil.

This is particularly common after shaving. Air can get into the internal oils if you've got an open hair follicle, or a blocked pore after shaving. The oxidizing process causes the darkening of the skin.
