Beauty marks are small, dark spots on the skin that can be either natural or artificial. The two most common types of beauty marks are TENS, which stands for Transient Epidermal Melanocytic Nevi, and MOLES, which stands for Melanocytic Nevi. TENS are usually flat and light brown in color, while MOLES are raised and darker in color. Both types of beauty marks are considered attractive and fashionable, and have been used as a form of body decoration since ancient times.
