Why Do I Have Freckles?

The video explores the concept of freckles, explaining that they are small, tan spots on the skin caused by melanin. Melanin is responsible for skin, hair, and eye color and helps protect the skin from sun damage. Freckles form when certain skin areas produce more melanin in response to sunlight. Genetic factors, such as having lighter skin or parents with freckles, increase the likelihood of having freckles. Freckles can change over time, fading in winter or disappearing as one ages.
