Melanocytes can be damaged while its product protects the skin from the sunlight. This results to a collection of melanin which can spread into the dermis. This damage will to the skin as small, brown spots called freckles.
Melasma results from overproduction of melanin from melanocytes. This causes darkening of the skin and it is larger compared to freckles. This may occur due to prolonged exposure to the sun and also hypersensitivity to sunlight. Estrogen supplements, birth control pills and pregnancy can also trigger occurrence of melasma due to increase in release of hormones in the body.
