Hyperpigmentation (Dark colored spots) and Hypopigmentation ( Light colored spots)

Melanin is the substance which gives the skin its color and hyperpigmentation occurs in case of its increase. In situations like pregnancy or Addison's disease melanin increase may happen. Sunlight exposure is one of the main reasons of hyperpigmentation and it may darken hyperpigmentated regions even more. Other reasons of darkening of skin color may be antibiotics, antiaritmics, antimalarian drugs.

Albinism patients have to use sun protection all the time because they have higher rates of exposing to sun damage and having skin cancer
Loss of color due to skin wounds: If a skin infection, wounds or burns occur it may cause hypopigmentation on that region. This situation does not cause permanent loss of color but it may take long for the skin to get colored again.
